Here comes summer Ready for a break after a year that’s been flat tack?

THE SUN IS flooding into my workspace and the sky is a clear cloudless blue. All of which signals that it’s summer and time for a holiday after another full-on year for the NZ Plumber team. We hope you’ll be doing the same in your workplaces.

This has been a booming but challenging year for construction industry employers. The new government is promising fees-free training for firstyear apprentices from 1 January, and it would be good to see employers given similar support to take them on to help keep up with workload demands.

Slowly but surely, the word is getting out to young people that university isn’t the only option on leaving school. Construction trades apprenticeships offer a solid career path that pays from day one, with plenty of opportunity to move up the promotional ladder.

This year has seen Plumbing World’s first-ever Young Plumber of the Year competition (see p64), a fantastic initiative to attract more young people to our trades. The Masterlink team has also been out and about at trade shows, school and careers events to spread the message about apprenticeships in our industry (p66).

Thank you to all our advertisers and to those who have been profiled in the magazine during the year. Your stories and projects are what bring the pages to life. Thanks, also, to the many specialist writers and contributors who have provided articles for the magazine—and to the Master Plumbers’ Business Partners for their support of NZ Plumber and their expert input into the new technical themes, launched this year.

Have a wonderful Christmas and a relaxing summer break, wherever it takes you. We’ll be back with the February-March edition at the end of February.

Clay trench installation Love the NZ Plumber magazine. It is jam packed with great information every plumber can use. No wonder the magazine is award winning—well done.

I just wanted to comment on the upcoming changes to the plumbing apprenticeship to a plumbing and drainage apprenticeship, which I believe is a good thing. It would be great if there was a pathway for existing plumbers to become qualified as drainlayers.

Page 18 of the last magazine showed a drainlayer installing pipe into a clay trench. This drain should be on a bedding material placed in the base of the trench before the pipe (AS/NZS 3500.2.2015 5.4.1) and there are other smaller things in this photo that the supervisor could improve on.

Peter Jackson, Peter Jackson Plumbing, Kapiti Coast Ed: Thanks for your letter, Peter—this edition's prize voucher is coming your way. The photo was supplied by The Skills Organisation, so we asked them for their response, which is given below.

"At the time this photo was taken, this section of pipework was being pre-fitted into the trench before being lifted back out and fines placed beneath and around the pipework. With any photo shoot, Skills ensures there is a subject matter expert present to confirm best practice and compliance."

MASTER PLUMBERS NEWS

Engaging with government WITH THE CHANGE of government comes an increased workload for Master Plumbers as we start engaging with the new ministers to ensure our views are represented.

We have had preliminary discussions with Building and Construction Minister Hon Jenny Salesa, Housing and Urban Development Minster Hon Phil Twyford and Education Minister Hon Chris Hipkins.

Master Plumbers believes five key industry issues need addressing with some urgency. We have been expressing our concerns on these matters and hope that, with the change in government, they may be given higher priority.

Members need to be aware that the process can take time, but we will keep you informed.

1. Skills shortages In our opinion, the shortage of qualified plumbers, gasfitters and drainlayers is the most pressing issue. With the current shortfall of approximately 9,000 new homes in New Zealand, there are not enough tradespeople to meet demand. In our sector alone, there is a perceived shortage of approximately 2,200 plumbers—with 600 short in Auckland alone last year.

With just under 19% of nationwide plumbing firms employing apprentices, we consider that the government must provide some kind of financial support to incentivise employers to take on more apprentices.

2. Apprentice training delivery We frequently hear concerns from members about the quality and consistency of apprentice training being delivered by the 11 polytechnics around NZ. We have raised these issues with

8

December 2017/January 2018

Master Plumbers wants to see the new government addressing five top-priority issues for our industry.

The Skills Organisation and are pleased to confirm that an independent review of all polytechnics is underway. Master Plumbers is looking forward to seeing what recommendations come from this report.

3. Plumbing self-certification For some time, we have been advocating for plumbers and drainlayers to be able to selfcertify their work. Gasfitters and electricians can self-certify their work, yet plumbers and drainlayers must have all their work inspected and signed off—and a significant amount is going unchecked due to lack of resource within some of the larger BCAs. We were advised by the previous government that self-certification by plumbers and drainlayers would be treated as part of wider reforms for the Building Act, but we have seen no progress on the promised review of occupational regulation signalled in 2015.

4. PGD Act review The Plumbers, Gasfitters & Drainlayers Act 2006 Act is now 11 years old and it is four years since MBIE was required to start the review. However, our industry continues to wait for a response from MBIE to submissions made in 2015 following initial public consultation.

5. Plumbing product quality For some time, Master Plumbers has been publicly voicing its concerns about the number of inferior plumbing products infiltrating the NZ market. We want to see the government setting and monitoring rigorous standards for the importation and supply of plumbing products.

We understand MBIE has commissioned research into the Australian WaterMark scheme to see how it might operate here, and we hope to see their report in the near future.

In the meantime, as we approach the end of 2017, I would like to take this opportunity to thank all staff at Master

Plumbers, Masterlink and NZ Plumber for their hard work during a very successful year. I’m happy to report that we have met many of our strategic goals and our organisation and businesses are growing, though there is still plenty more work to be done.

We wish all members and Business Partners a Merry Christmas and hope that everyone enjoys a well-earned break. We look forward to a strong and prosperous New Year for the industry.

Legionnaire’s disease concerns In recent media coverage, plumbers have been expressing concerns about the lack of Legionellosis controls for water supplies.

Master Plumbers has been in discussions with the Department of Health and the Building Systems Performance group within MBIE about this issue. A preliminary report from independent research being conducted at Otago University suggests there are more cases of Legionellosis in New Zealand than currently thought.

We feel there should be a requirement for six-montly testing of hot water systems in high-risk environments, such as retirement villages, hospitals and early childhood centres, to ensure safe water temperatures are maintained and there are no dead legs in the plumbing system.

The Ministry of Health has guidelines on the prevention of Legionellosis in NZ, which recommend six-monthly testing in buildings of this kind—and we advise members to notify relevant clients that this frequency of testing is standard good practice.

Communicating with members

We recently sent out a communications survey.

Thanks to those who took the time to provide comments in the communications survey we sent out in November. Although the response was disappointingly low, there were several points of interest: • The three main ways respondents got their news were online, TV and radio.

• The three most popular social media platforms were Facebook, Instagram and Linkedin.

•

•

The most popular trade publications were NZ Plumber, the PGDB InfoBrief e-news and Rheem Off-Site magazine.

The preferred method of receiving Master Plumbers' communications were (in order of preference): Newstube e-news, direct email and NZ Plumber.

For those who like up-to-the-minute updates, like us on Facebook at facebook.com/masterplumbersnz

Code of Conduct update

Two changes have been made to the Master Plumbers Code of Conduct.

Adherence to the Master Plumbers Code of Conduct and Code of Practice is a fundamental requirement of membership. It is updated from time to time, with the latest version always available to view in the members’ area of the website.

To ensure that all members have fair, open and transparent business practices, changes have been made to Clauses 2 and 5 of the Code of Conduct, and 6.1, 11 and 16 of the Code of Practice.

The document now also includes reference to the Quality Assurance processes that are carried out with new and existing members.

Members completing their Annual Quality Assurance Declaration will need to confirm they have read and agree to abide by the current Code of Conduct.

Find the Code of Conduct under Rules & Strategy in the member log-in at www.masterplumbers.org.nz

Modification to Guarantee

What happens if a nonmember certifies work on behalf of a member?

The Master Plumbers Guarantee has been modified in relation to the Rules of the Society (Rule 5.1). Below is a quick and easy explanation of the change: “If a Master Plumber undertakes something such as gas work, which he is not certified to do and chooses to use a non-Master Plumber to certify the work (whether this is done for payment or not), the customer will be covered by the Master Plumbers Guarantee. The Master Plumber, however, will be fully liable for any workmanship issues that arise from the completed work.”

It is the Society’s strong preference that Master Plumbers only use another Master Plumber to certify any work they have done that sits outside the scope of their own certification.

Find the updated Master Plumbers Guarantee rules under Rules & Strategy in the member log-in at www.masterplumbers.org.nz

Ongoing Quality Assurance

New measures have been introduced for the ongoing Quality Assurance assessment of members.

At the Master Plumbers’ Half-Yearly Meeting in October (see p16), Operations Manager Margaret Dawson outlined new steps for the Quality Assurance process for new and existing members.

The face-to-face review of all businesses

prior to joining will continue, as will the annual Quality Assurance Declaration— though members are now required to submit their online Declaration by the end of February each year.

From January 2018, random reviews of no fewer than 15 percent of the membership

will be conducted each year, with support provided to members if needed in reaching the quality benchmark.

If members have any queries about the Quality Assurance process, please email mdawson@masterplumbers.org.nz

Supporting NZ Talent

Master Plumbers backs the ‘NZ Talent’ initiative.

Master Plumbers has joined nearly 200 business and organisations in getting behind NZ Talent—an open letter to the New Zealand public about changing perceptions of what it means to be ‘talented’.

“While traditional tertiary education has its place, it is one of many pathways to

10

December 2017/January 2018

employment,” says the letter. “Internships, apprenticeships, new micro-credentials, on the job training, online courses and badging are all effective ways to learn.”

The organisations listed on the NZ Talent website—including Master Plumbers and Masterlink—confirm that they do not require tertiary qualifications for a range of

specific, skilled-based roles.

One place people will be able to find these jobs is on the Trade Me Jobs site, with a clear indicator that no tertiary qualification is required to apply.

IN FOCUS

Retentions Q&A Some questions about retentions were raised at a recent online seminar for quantity surveyors.

THE NEW RETENTION regime came into effect from 31 March 2017 with the aim of providing protection for retention money.

In April 2017, the Specialist Trade Contractors Federation, Registered Master Builders and NZ Institute of Quantity Surveyors issued Retentions Bulletin to outline the new regime and answer common questions.

This October, they released a second Retentions Bulletin to answer further questions raised at a webinar for NZIQS members, presented by Peter Degerholm of Calderglen Associates.

Retentions Bulletin No.2 also provides an updated summary of the retentions regime, which we reproduce here.

The retention regime—in summary The regime incorporates the following last-minute changes that were introduced via the Regulatory Systems (Commercial Matters) Amendment Bill (RSB): • The regime applies only to retentions on contracts renewed or entered into on or after 31 March 2017 • Payers must, by default, hold retention money on trust in the form of cash or other liquid assets that are readily converted into cash, but may elect instead to obtain a ‘financial instrument’, such as insurance or a payment bond to provide third party protection.

The following is a brief summary of the provisions of the retention regime, with references in subscript to the relevant sections of the Act. A full copy of the Act including all amendments may be downloaded free of charge from www.legislation.govt.nz References in the Act to ‘Party A’ and ‘Party B’ are substituted with ‘payer’ and ‘payee’ respectively.

Retentions (‘retention money’) definition and application • The retention regime aims to provide protection for retention money CCA Subpart 2 Part 2A • Retention money is broadly defined s18A as ‘an amount withheld by a [payer] from an amount payable to a [payee] as security for the performance of [the payee’s] obligations under the contract’. It effectively covers any amount withheld or payment arrangement that acts as a retention.

• As no minimum (‘de minimis’) amount has been specified in regulations s18B(2), the regime applies to retentions on all new, or renewed, contracts from 31 March 2017 s11A(3) • As the regime applies only to ‘commercial construction contracts’ s18B(1) it effectively covers all contracts or subcontracts, other than those directly with ‘residential occupiers’.

Protecting retentions • There are now two ways for payers to protect the retention money that they withhold from their payees: 12

December 2017/January 2018

1. Default arrangement—money must be held on trust •

•

• •

•

•

• •

Retention money must be held ‘on trust’ s18C(1) in the form of ‘cash or other liquid assets that are readily converted into cash s18C(2) The retention money held on trust does not need to be paid into a separate trust account, and may be mixed with other money in the payer’s accounts s18E(2) Proper records must be kept of all transactions s18FC The trust status of the retention money ends only when the retentions are paid out, the payee gives up its claim, or when the money otherwise is no longer payable under the contract or by law s18C(3) Retention money held on trust is not available for payment of the payer’s debts and cannot be taken by a receiver or liquidators 18FA Retention money can only be used by the payer to remedy defects in the payee’s performance of its contractual obligation s18E(1) Retention money may be invested at the payer’s risk in accordance with the Trustee Act 1956 s18F The payer must pay all costs in administering any trust s18I(1)(c)

IN FOCUS

2. Alternative arrangement—retention money may be protected by a ‘complying instrument’ • The payer does not need to hold retention money on trust to the extent that there is a complying financial instrument s18C(1A), s18D such as a bond or guarantee s18FB(5)

•

The instrument must: ° Be issued by a licensed insurer or registered bank s18FB(2 & 8)

° °

°

Be issued in favour of, or endorsed with the interest of, the payee s18FB(3)(a) Require the issuer to pay retention money to the payee if the payer fails to pay when contractually due s18FB(3)(c & d) , provided that the payee complies with reasonable terms and conditions in making such claim s18FB(6) The payer is responsible for ensuring that all premiums are paid and up to date s18FB(4)

Requirements for accounting and records • The payer must keep proper accounting and records of all retention money s18FC(1) that comply with generally accepted accounting practice, are auditable, and show: - All retention money held on trust - All retention money protected by ‘instruments’ - All dealings and transactions in relation to retention money or instruments’ • - The payer must keep proper and readily verifiable records of all instruments s18FC(2) • - The payer must make records of accounting and instruments freely available to payees at all reasonable times s18FC(4) Interest on late payment • The payer will automatically be liable for interest at the contractual interest rate when retentions are released late s18G

Prohibited provisions of contracts • Any term of a construction contract will automatically be void s18I which: - makes payment conditional upon anything other than the payee’s completion of its contractual obligations - makes the retention release date later than the date when the payee has completed its contractual obligations - requires the payee to contribute to the cost of administering any trust.

Frequently asked questions These are just some examples of the questions answered in Retentions Bulletin No.2. To read the Q&A in full, go to www.nziqs.co.nz/Resources/Construction-ContractsAmendment-Act-2015

Q1: Can main contractors offset retentions on what is owed to them by clients against what they owe to subcontractors?

A: No. The Act is clear that all retention money that is withheld by any payer in respect of a commercial contract entered into or renewed from 31 March 2017 must be held ‘on trust’.

Q2: Does, say, a 40-unit residential complex get defined as ‘residential’ or ‘commercial’, hence falling into the trust?

A: As there is no longer a ‘residential construction contract’, the answer lies in the definitions at section 5 of the Act: • A commercial construction contract is ‘a contract for carrying out construction work in which none of the parties is a residential occupier of the premises that are the subject of the contract’.

• A residential occupier is ‘an individual who is occupying, or intends to occupy, the premises that are the subject of a construction contract wholly or mainly as a dwellinghouse’.

Consequently a contractor who has a contract with a developer to construct a residential complex has a construction contract, as neither of the parties to that contract is a residential occupier.

However a contractor doing fitout work for an individual apartment owner who occupies or intends to live in that apartment has a contract with a residential occupier, so the fitout contract would not be a commercial construction contract. Of course, a subcontractor working for the contractor in either case has a commercial contract, as neither of the parties is a residential occupier.

Q3: Most banks issuing bonds insert an ‘on demand’ clause. Would this trump any need to notify under the contract?

A: The Act refers to the retention bond as an ‘instrument’, and states: • The instrument must—… (b) require the issuer to pay the retention money to party B if party A fails to pay that money on the date on which it is payable under the construction contract… 18FB(3) • Nothing in subsection (3)(b) or (c) prevents the instrument from containing reasonable terms and conditions that relate to the manner or time in which party B must submit a claim 18FB(6)

A payer would be unwise to purchase a retention bond that was so open, as it could lead to the inappropriate calling-up of the bond. A payee should be required to demonstrate to the bank that the retention money is overdue, has not been paid, and that there are no reasons for the retention money not having been released. > December 2017/January 2018

IN FOCUS

Q4: Who will withhold the retention money on the trust regime—the contractor or the client/owner?

A: Whoever withholds retention money from a payee must hold that full amount on trust: • Any developer/owner/principal withholding retentions from a contractor • Any contractor withholding retentions from its subcontractors and suppliers • Any subcontractor withholding retentions from its subsubcontractors and suppliers.

Q5: Retentions is only relevant to commercial projects and not residential projects. What about mixed use projects?

A: The definition of a commercial construction contract merely distinguishes contracts with residential occupiers from all other construction contracts. In short, every contract is a commercial construction contract unless the client is a residential occupier (ie, home owner). See also Q2 above.

Q6: Is the provider of bond instruments a third party accounting firm or a bank?

A: As to the provider of the bond instrument, the Act states: • The issuer of the instrument must be— (a) a licensed insurer; (b) a registered bank; (c) any other person, who is not an associate of party A, prescribed or within a class prescribed in regulations 18FB(2) Under (c), any such instrument must be provided by a registered bank or licensed insurer. The bond instrument is an option for payers who do not wish to hold retention money on trust.

Q7: Does GST on retentions need to be held?

A: This is a question for an accountant, but a layman’s view suggests that in practice only the GST exclusive amount shown in payment schedules would be held on trust, and that the matter would only arise in the event of liquidation.

As IRD hold the balance of any GST transactions, the payment by a liquidator of retentions held in trust to a subcontractor will be plus GST, and the company in liquidation would need to cashflow the GST component and claim it back from IRD. This will undoubtedly be a matter for the courts to deal with, particularly where the payer was hopelessly insolvent.

Q8: Why should principals and main contractors hold performance retentions when progress payments are assessed against performance?

A: It is difficult to say definitively why, but some parties may

14

December 2017/January 2018

see it as a safeguard to enforce performance. In any event, the Act only provides security for retention money that is withheld, but does not advocate a view on the merit or otherwise of retentions.

Q9: Where bank funding is involved, does this mean the value of retentions should be drawn down and then held in a trust account?

A: Yes, except to the extent that the payer provides a bond instrument from a bank or insurer. There is no requirement to establish a separate trust account with an accountant or bank: • Retention money held on trust may be held in the form of cash or other liquid assets that are readily converted into cash s18C(2) However, the trust status of the retention money must be clear, auditable and traceable at all times: • [A payer] must keep proper accounting records of all retention money that— (a) correctly record— (i) all retention money held on trust; and (ii) all amounts of retention money protected by instruments issued for the purpose of this subpart; and (iii) all dealings and transactions in relation to retention money or instruments; and (b) comply with generally accepted accounting practice; and (c) are readily and properly auditable. s18FC(1) Q10: Where do I get further information?

A: If you are a payer, you should take specific advice from your accountant, lawyer and bank in order to ensure that you comply with the regime and can meet your cashflow requirements.

At the half-yearly There was a packed agenda at the Master Plumbers half yearly meeting in October, including presentations from the PGDB and Skills.

REPRESENTATIVES FROM MASTER Plumbers nationwide Branches and Associations attended the half-yearly meeting in Wellington this October.

The day began with economic insights on NZ’s construction industry by Gareth Kiernan, Chief Forecaster at Wellingtonbased economic consultancy Infometrics.

Advocacy work

Master Plumbers CEO Greg Wallace followed up with a report on the advocacy work being undertaken by the Society.

Master Plumbers is represented on the PGDB Stakeholder Liaison Group, which meets every quarter to provide feedback on PGDB initiatives and discuss industry issues. The Society has also had significant input into the development of the new apprentice qualifications, working with Skills and the PGDB on proposals for change that will come into being in 2018.

A major project currently underway is the revision of the AS/NZS 3500 Standard series. Master Plumbers is the only organisation to represent NZ installers on the committee for this joint Australian/ New Zealand Standard (see p36).

Greg had also been in discussions with the Australian Master Plumbers Associations around plumbing product quality concerns. BRANZ would be consulting with Master Plumbers and researching the Australian WaterMark certification scheme to inform its upcoming report on the potential risks posed by substandard plumbing product in New Zealand.

Greg has recently been appointed Vice President of the Specialist Trade Contractors Federation 16

December 2017/January 2018

Greg has recently been appointed Vice President of the Specialist Trade Contractors Federation, of which Master Plumbers is a member. The Federation is currently lobbying strongly for better administration and policing of Standards in New Zealand.

Code of Conduct updated

The Master Plumbers Code of Conduct has recently been revised to include reference to the Quality Assurance process and to ensure members behave in a professional, fair and transparent way with other members. “Poaching apprentices from other members is behaviour that falls outside the Code,” said Operations Manager Margaret Dawson. “If cases of this are brought to our attention, we will investigate them.”

The Master Plumbers Guarantee Rules had also been updated to reflect a clarification proposed by the Wellington Master Plumbers at the 2017 AGM. If a Master Plumbers undertakes work he is not certified to do and chooses to use a non Master Plumber to certify the work (whether for payment or not), the customer will still be covered by the Master Plumbers Guarantee. However, the Master Plumber will be fully liable for any workmanship issues that arise from the completed work.

“It is our strong preference that members only use another Master Plumber to certify any work they have done that sits outside the scope of their own certification,” said Greg.

Quality Assurance & training

Margaret Dawson outlined new steps for the Quality Assurance process. The review of businesses prior to joining would continue, as would the annual Quality Assurance Declaration—though members would now be expected to submit these by the end of February each year instead of November.

An ongoing Quality Assurance

assessment of member businesses would launch in January 2018. Random reviews of no fewer than 15 percent of the membership would be conducted each year, with support provided to businesses that weren’t reaching the quality benchmark.

The revitalised Master Plumbers training timetable had been well received in most regions, said Margaret, with technical courses currently better attended than ‘soft skills’, such as customer service and marketing.

Marketing focus

During the year, Joanne Caine had joined Master Plumbers in the new role of Communications & Marketing Advisor.

A comprehensive marketing plan had been developed for both Master Plumbers and Masterlink for the year ahead. This would include a refresh of the Don’t Risk It consumer campaign and the roll-out of the Master Plumbers Recommends product endorsement initiative.

An online marketing strategy was also to be developed. ■

PGDB progress At the half-yearly, Plumbers, Gasfitters and Drainlayers Board (PGDB) Chief Executive Martin Sawyers acknowledged the good working relationship between the PGDB and Master Plumbers.

The issues in focus for the PGDB, he said, were CPD, apprentice training, unauthorised work, registration and licensing fees, and better utilisation of new technology for online registration processes.

closely with Master Plumbers and Skills to develop the new apprentice Level 4 qualifications. Although these were primarily the responsibility of Skills, the PGDB had a key interest in ensuring the competency of tradespeople, he noted.

From June 2018, the PGDB’s Tradesman registration exams would be offered more regularly and in electronic format as an integral part of the Level 4 qualification.

CPD sessions The second year of face-to-face CPD sessions had been successfully completed and the online version was now available for those who hadn’t attended this year’s roadshow.

The PGDB had already picked topics for next year’s roadshow, including:

Unauthorised work There were two categories of unauthorised work, said Martin: work carried out by qualified tradespeople without a current licence, and work carried out by unqualified people. Whilst a warning was usually sufficient for the first category, the PGDB had no sympathy for the second, he said.

With concerning levels of unauthorised work being carried out in some areas, particularly in Auckland, the PGDB had run a consumer education campaign on sorting ‘the pros from the cons’.

In 2018, they would translate the campaign into other languages to reach immigrant consumers, whilst also

supporting immigrant tradespeople to follow the New Zealand pathway to qualification and licensing.

Fees review The PGDB’s three-yearly review of registration and licensing fees was due in 2018, with the new fees coming into effect from 1 April 2019. Industry comment would be sought and it was hoped to keep the fees at the same level as they were currently, he said.

Training our trades Skills Organisation representatives Lance Riesterer and Di Lithgow attended the meeting to outline key activities in apprentice training for our trades.

1. Apprentice volumes As at October 2017, Skills had had approximately 800 new PGD apprentice enrolments during the year—and forecast more than 1,000 by the end of the year.

There had been massive growth over the last two years, said Lance Riesterer, with a 20 percent increase in the number of trainees under Skills management in the past three years. The main growth had been in the ‘golden triangle’ of Auckland, Hamilton and Tauranga, he said.

With increased numbers of apprentices

came increased demand for block courses, and the total numbers held had almost doubled between 2013 and 2017.

2. Apprentice qualifications The goal of the proposed new PGD apprentice qualifications was to improve consistency and credibility, said Di Lithgow. The new programmes had required a great deal of time and effort, with around 30 people in total involved in the programme development.

“Our goal is for the programme to have

nationwide consistency,” said Di. “From the training and assessment resources to the off-job training delivery and qualification outcomes, the programme should be the same wherever you go.”

3. Programme delivery review Also on the agenda at The Skills Organisation was an independent review of PGD programme delivery, with comparisons to be drawn between the NZ and Australian models. ■

REAL LIVES

Second to none!

Julian Parker of Lewis Plumbing in Rotorua has won the coveted title of Young Plumber of the Year in Plumbing World’s inaugural competition.

Shelley Burt talks to Julian and his boss Jon Lewis about the experience.

“IT DOESN’T MATTER what work you undertake, if you can stand back and look at how you could have done it better, that naturally leads to better results,” says Jon Lewis of Master Plumbers member business, The Lewis Plumbing Company in Rotorua.

Jon is referring to his employee, Julian Parker, 25, who recently won Plumbing World’s 2017 Young Plumber of the Year Competition. According to Jon, Julian has never failed to rise to the challenges that come his way. He has the respect of his colleagues and workmates, and shows strength of character and the ability to adapt to new situations, making him a recognised leader within their business.

“Julian’s core values resonate with the company values of honesty and integrity, and so his development into an exceptional plumber has been a natural transition,” says Jon. Julian started on his apprenticeship when he was just 17.

After a stint in post-earthquake Christchurch, he returned to Rotorua and joined Lewis Plumbing three-and-a-half years ago as a Tradesman Plumber. He is now a Certifying Plumber, a Tradesman Gasfitter and working towards becoming a Certifying Gasfitter in 18 months’ time.

“I enjoy the diversity—whether it’s a tricky issue, or new builds, or commercial,” says Julian. “Every day is different, and you meet different people: builders, customers, suppliers. I also enjoy undertaking work I’ve never done before and just learning from it.”

Above: Julian back in Rotorua with his Milwaukee power tool pack—just one of heaps of prizes he received for winning the competition.

“It was awesome”

The first round of the competition and Regional events were held at local Plumbing World branches. Julian won first spot at his local Rotorua branch, with the company’s two apprentices, Dave and Ben, gaining third and fourth. At the Regional event in Tauranga, he again secured first place.

Then came the Final, held at Wintec in Hamilton. “Like the two other events, we did a theory exam followed by multiple practical assessments on new products, most of which we hadn’t seen before,” says Julian. “Everything had to be done faster now.

There wasn’t enough time to answer all the questions in the theory exam, so you did what you could as fast as you could!

The three-hour practical exam was setting up a small unit (like a bathroom) with a hot water cylinder, drainage and fixtures. It was like having 100 customers watching over your shoulder as you work!”

But Julian wasn’t fazed. “It was awesome. The whole experience was amazing. I knew it would be tough, but it was a lot more competitive than I expected. And quite tricky. I took a lot away from it—you get to meet some good people and learn about the industry. Most entrants I’ve spoken to want to do it again.”

Achieving goals

December 2017/January 2018

Julian is grateful to Plumbing World for organising the event and believes the competition furthers knowledge by testing your skills, learning how to use things you haven’t used before, and for comparing how your skills stand alongside others in the industry. “I’d also like to thank the suppliers, sponsors and organisers for making the event possible.”

“Julian’s success has given our other young plumbers future goals they may not have realised they could achieve,” says Jon. “It’s important that the plumbing industry recognises our future young plumbers. I’d like to thank Andrew Lewis from Rotorua Plumbing World branch for his support in getting all of my young plumbers to the competitions.”

Whilst part of the prize package is a luxury trip to Plumbing World’s overseas convention in Fiji for Julian and his partner, Shannon, Julian says, “I would have done this purely for the experience. The whole time I really wanted to compete to meet people in the industry.” ■

On-site sewage treatment Treatment for Auckland Pressure sewer networks

WASTEWATER TREATMENT

On-site sewage treatment Australian on-site sewage treatment company CSS has come up with a new solution for upgrading commercial plants. Managing Director Stephen Pereira explains.

RURAL AUSTRALIA HAS many private sewage treatment plants, especially in regional tourist belts, such as the Yarra Valley, Great Ocean Road and Mt Dandenong.

These small, off-the-shelf plants service restaurants, wineries, hotels, convention centres, mining camps and caravan parks, amongst other commercial premises.

Most plants discharge to the land via irrigation systems, or to a river.

Treatment plants of this kind started appearing from the mid to late 1960s, when regulations demanded better levels of environmental protection.

Numerous variations are available, but all are based on the same simple biological process: 1. Biological treatment of solids (no air/anaerobic) 2. Biological treatment of liquid (with air/aerobic) 3. Separate water from beneficial bacteria 4. Disinfect cleaned water.

• •

Overloaded disinfection system Elevated solids, BOD and bacteria.

Elevated concentrations of any or all of these can be incredibly damaging to the environment, and are targeted by the Environment Protection Authority for obvious reasons.

Options limited

Short of replacing the whole plant—with the accompanying business disruption—the options available to small plant operators have been limited.

They are either prohibitively expensive, due to the chemicals and operator time, or don’t achieve what’s required.

Combined Separation Systems (CSS) has investigated this issue and applied a fresh approach based on recent development work conducted by the company in the industrial space.

The result is a world-first, patent pending membrane/UV package plant that requires minimal operator time and expertise.

For many years, membrane has been the best available technology worldwide for achieving step three of the treatment process.

However, until now it has required a team of full-time engineers and technicians to run the technology.

Treatment for Auckland

Orua Bay Motor Camp has become the first site in the Auckland area to install an AES on-site wastewater treatment system.

THE AES (ADVANCED ENVIRO-SEPTIC) system at Orua Bay Motor Camp was designed by engineer Fraser Walsh of Ground Consulting in conjunction with NZ distributor Environment Technology (ET), and installed by Waiuku drainlayer Jim Douglas.

Property owner Jim Caldwell chose the system as it suited the small site, was visually unobtrusive, low maintenance and has limited effect on land usage. The existing septic tanks have been retained as part of the upgrade.

ET introduced the system in 2013. The AES bed can disperse the effluent, as in this situation, or it can be dispersed through dripper irrigation.

“AES provides treatment quality which easily meets NZ Standards while minimising the risk of groundwater contamination and preventing the receiving soil from becoming clogged over time,” says ET Director Dick Lamb, who also attended the installation.

To date, four other campgrounds in the South Island have installed the system: Lake Okarito, Paringa and Hokitika campgrounds on the West Coast and Greenwood Park Holiday Camp in Nelson, where the system has been installed under the parking area.

“You can put it under a hard surface and utilise every bit of land you have,” says Greenwood Park owner Chris WhiteJohnson. “With the old sand filtration system, you had to isolate a whole area and so lost a lot of available space.”

For Ian James of Okarito Campground, the advantage of the system was the ability for it to be installed above ground to overcome the high water table.

Peter Blight of Hokitika Campgrounds says the system allows large variations in daily loading and intermittent usage, and provides a quick start-up after periods of non-use.

AES can be up-scaled or downsized to suit the application, from single dwellings to schools, marae and commercial installations. Subdivisions can use individual systems or a larger de-centralised AES system that services several dwellings.

AES treats wastewater by providing a habitat for microorganisms to self-colonise within passively aerated pipes, installed in a bed of sand or recycled crushed glass.

The product has just completed initial testing at the National Testing Facility, OSET in Rotorua, where preliminary results are confirming advanced secondary treatment quality, in line with previous overseas testing.

AES has been installed in over 400,000 sites worldwide. In New Zealand, over 300 systems have been installed and ET offers free training for designers and installers nationwide.

He also became the first in the country to use recycled crushed glass for the system ‘sand’, “because it is the cheaper option and because it’s better for the environment, but performs just as good a job as 2A sand from a gravel pit”.

Richard wanted a system that didn’t require any external energy input or regular servicing, and called in Grant Wooster of Dynamic Drainage from Rolleston to Above: Designer and installer help install the system.

Richard Reay.

Fulton Hogan in Canterbury produces and supplies 2A crushed glass sand that meets the AES sand specification. “This is great news to have a suitable use for recycled bottle glass,” says Dick Lamb of Environment Technology (ET), distributors of AES in New Zealand. “It also means installers and other homeowners have another costeffective option when looking for a suitable aggregate.”

AES system components are also made with significant quantities of recycled plastic.

The system treats wastewater using self-colonising natural microorganisms within passively aerated pipes installed in sand or a recycled glass bed. Effluent is treated to advanced secondary quality before passively dispersing into the soil.

The installation is easily adapted to smaller or larger wastewater flows, says Dick, and systems are in place globally from 400 litres per day up to 200,000 l/day in a communitywide application in the US State of New Hampshire.

AES can be retro-fitted to existing septic tanks as an upgrade if the existing disposal field has failed. ■

PROJECT SPOTLIGHT

BY THE END of this year, all Christchurch justice and emergency services are expected to be brought together in the new purpose-built Justice & Emergency Services Precinct. The precinct, which will be used by around 2,000 people each day, is the first major public building to be built in Christchurch by the government since the earthquakes of 2010 and 2011.

John Leen Plumbing worked for main contractor Fletcher Construction on the project, having strategically set up a new JLP division in Christchurch in late 2013. JLP initially tendered and won the in-slab and civil works—which they started in mid 2014—before securing the full plumbing package for the balance of the building. At this point the firm sought products, planning and design expertise for the Marley Akasison Siphonic Drainage system.

Behind the scenes

As Marley’s NZ-based National Technical Sales Engineer, Steve Skidmore and his team assist professionals in carrying out siphonic designs locally and liaising directly with expertise within the wider Aliaxis group (Marley’s parent company), which has 15,700 staff Above: Marley National across 40 countries.

Technical Sales Engineer “The Achilles heel of other Steve Skidmore. siphonic systems is the design team being offshore, often delaying installs when changes are required,” says John. “Marley’s behind-the-scenes support team are always exceptionally helpful with technical answers and support.”

“The precinct buildings are complex, with inputs and requirements to consider for all disciplines,” says Steve. “JLP’s use of Building Information Modelling [BIM] meant coordination between the requirements of architecture, structural, plumbing, mechanical, electrical, data and HVAC could all be modelled in advance to secure a route for siphonic pipework through the ‘busy’ building ceiling spaces and service risers.”

The software allowed JLP to create the full plumbing install in conjunction with the structure and other sub trades, and review the clashes on desktop in 3D. “This is an exceptionally good process to ensure the bulk of the works are coordinated prior to site install,” says John.

BIM enabled JLP to install major pipe runs very early in the construction stage, working around other trades without major conflict issues.“Like all new technologies, there were some fish hooks, so to speak, but they were well outweighed by our ability to get in front of the installation programme.

“The greatest learning is that you need everyone in the waka paddling in the same direction. If a section of work is not modelled, then you don’t know that you might have a clash.”

Size and seismic

A lot of the complexity came down to the sheer size of the project—and Christchurch’s high seismic activity brought with it additional requirements. The allowance for movement in the design of the buildings meant the many soil, stormwater, water Opposite: Siphonic roof drainage is a feature of the new Justice & Emergency Services Precinct in Christchurch.

“This meant there was significant emphasis put into services having dual standby and duty type, including dual water supplied from adjacent streets, water storage supply tanks, sewer storage tanks, dual gas supplies, backup power supply via generators, fire system backup supply, and various security, data, communications and BMS type support.”

With the project’s size also came the complication of getting sufficient staff. At the height of the project, JLP had around 30 staff onsite at one time, including contracts admin, quality assurance, site foreman and a variety of trades. This included around 12 Filipinos, four Frenchmen, various English and Irishmen and a base of Kiwis.

“If it were not for our ability to employ overseas immigrant tradespeople, we could never have completed this type of project,” says John.

Roof and ceilings

Over 9,000m2 of roof area meant heaps of gutters and outlets, somewhere around 2.5kms of pipe, the equivalent Unirail support system, and around 110 outlets, all acoustically wrapped, seismically supported, air tested, then water tested from ground to flood level.

JLP also installed a complete Marley uPVC overflow secondary path system to deal with any water if for some reason all siphonic outlets managed to get blocked.

“The roof areas were all dual layer torch-on products which also determined the minimum falls from high points to outlets in the box gutters,” says John. “This kept all the outlets at approx 8m centres, so the fall in the gutters maintained the torch-on guarantee requirements.

“The Akasison siphonic system allows you to run all the horizontal pipes in the ceiling space level, so with the size of the building that meant very long runs, which, if falls were required, would have meant most of the system would be hanging through ceilings!

“Pipe runs with no falls excites architects and consultants, as this means less space required for services and high ceiling heights.”

The system is concealed and drains water rapidly, siphoning through small pipes close to the roof to maximise space, allowing more flexibility for routing of pipework, and giving more usable space inside the building due to small pipework that can be installed horizontally with zero gradient. ■

REAL LIVES

Repair by robot In a medical first for New Zealand, drainlayer Adam Squire recently underwent robot-assisted knee surgery. He talks to Matthew Lowe about the experience.

ADAM SQUIRE CAN only bear to watch a few minutes of his role in making New Zealand medical history before the sight of his own blood makes him look away.

This year, the drainlayer from Glenfield in Auckland became the first patient in the country to receive a robot-assisted partial knee replacement operation.

The medical team at North Shore Hospital gave him a USB stick with footage of the surgery but Adam, 52, admits he has been unable to watch a rerun of the 90-minute procedure.

“They had to cut out a bit of bone and I was given a full anaesthetic and epidural for the operation,” he says.

“I watched the first couple of minutes of the video once, but the moment the blood and bone started flying I turned it off. It would be different if it was someone else on the screen but when it’s your own blood it’s not great to watch. I’m not really sure why I asked for a copy of it now.”

US technology Adam was operated on using a Mako Unicompartmental Knee Replacement (UKR) system in which a surgeon guides a robotic arm to perform the procedure.

The technology, bought from the US by Waitemata District

Health Board, is designed to be less invasive for patients, to reduce the amount of trauma and should lead to a faster recovery time.

Adam spent only one night in hospital after his August operation and was back at work with Takapuna firm Galbraith Plumbing and Drainage two weeks later. People who have the standard procedure would usually need a month off work.

“The knee is still sore and I’m limping but the surgeon has said it will be 12 months before I am 100 percent,” he says.

“I was back at work in two weeks but I wasn’t on the tools and diving into trenches. I have been in the digger, driving, quoting and getting round our different sites.”

Test candidates Adam, a father-of-three, required the high-tech treatment after an injury in a motorcycle crash and the effects of osteoarthritis had seen his knee deteriorate over the years.

Above: Waitemata DHB’s Matthew Walker with the Mako Unicompartmental Knee Replacement system.

“A lot of the problems with the knee were wear and tear, but a lot also came from a motorcycle accident in 1993. I damaged the knee then and it has got worse and worse over time. The inside of the knee had essentially worn down to bone on bone,” he says.

“The surgeon said the knee needed to be operated on and he brought up the robotic surgery and seemed to think I was the perfect candidate because of my age and the fact that I was still working.

“First up I was a little nervous when they mentioned the robotic arm, but they said they have done millions of these operations around the world—it’s just we’re a bit behind here in New Zealand.”

Adam’s operation was the first of an estimated 60 per year that will be carried out at the North Shore Hospital as part of a study designed to compare results with current practice. Patients involved in the research will receive regular post-operative checks in the 10 years after their surgeries.

Waitemata DHB orthopaedics Clinical Director Matthew Walker, who operated on Adam, says the UKR system “allows consistently accurate placement of implants which ultimately means better outcomes for patients”.

“It reduces the magnitude of the surgery and improves the longevity of the implant, resulting in a shorter stay in hospital, earlier mobilisation, less pain, a greater short to mid-term outcome and increased patient satisfaction.”

Looking to the future In the future, North Shore Hospital will look at using the robot for other knee operations and possibly hip replacements.

After the surgery Adam had six weeks of regular physiotherapy to ensure he was getting mobility back into the joint and since then has “been pumping the exercise cycle and trying to walk as much as possible”.

He says he is looking forward to being able to walk pain-free again and enjoying time with his three grandchildren.

“The knee is feeling better week by week. It feels stronger than it has felt in a very long time and it is nice to know I can go back to the beach with the grandkids and be able to enjoy activities with them as they grow up.” ■

Soak pits When a soak pit is required, a building consent application with calculations for pit sizing must be lodged. So, how do you make the calculations? By Alide Elkink.

SOAK PITS, ALSO known as soakaways or soakage pits, are required for properties with no reticulated stormwater system provided by the council for removing water run-off from roofs and hard sealed surfaces. They can be: • a hole filled with rocks (see Figure 1) • a lined underground chamber with porous sides and base (see Figure 2), into which surface water can drain and be dispersed by percolation or soakage into the surrounding soil • a series of factory-made plastic drop-in modular interlocking infiltration cell blocks wrapped in geotextile fabric.

All options must be lined with a filter cloth with a mass per unit area of 140 grams/m² and a minimum thickness of 0.45mm.

In addition to water dispersal, a soak pit must also provide water storage to ensure water that drains into the soak pit will not overflow before soakage has occurred.

Their efficiency depends on their size, the permeability of the ground (the rate at which soakage occurs) and the rainfall intensity of the region.

Above: Figure 1 Rock soak pit.

Building consent required Where a soak pit is required, a building consent application with calculations for soak pit sizing must be approved by the building consent authority.

Guidelines for soak pit design, including sizing, are provided in Verification Method E1/VM1 to New Zealand Building Code clause E1 Surface water, or can be obtained from your local council.

Steps for designing a soak pit The first step in designing a soak pit is to determine the soakage rate of the natural ground. This is done by conducting a percolation test and, from the results of the test, determining the soakage rate.

Conduct a percolation test E1/VM1 provides a percolation test method in paragraph 9.0.2.

Percolation testing should be done when the groundwater is high and is carried out as follows: 1. Drill a test hole 100–150mm in diameter for the expected depth of the soak pit. If groundwater is struck before the expected depth is reached, the depth of the ground water is taken as the maximum depth of the soak pit.

2. Fill the hole with water and maintain it for at least 4 hours to presoak the ground.

3. Refill the hole with water to 750mm below the ground level (if possible).

4. Measure and record the drop in water level at 30-minute intervals maximum until the water is approximately 250mm from the base of the hole or for 4 hours, whichever occurs first.

5. Plot the results of the fall in the water level against the time it takes on a graph.

Determine the soakage rate Using the results of the water level drop rate from the minimum slope of the curve on the graph over a 10-minute period, determine the soakage rate (mm/hour) using the formula: soakage rate (Sr) = 6 × (water level drop in mm) / 10 minutes.

Where there is a significant decrease in soakage rate as the hole empties, disregard the lower rates and use a value closer to the average.

Calculate volume of storage required Once the soakage rate is determined, the volume of storage required (in m3) can be calculated according to the formula given in E1/VM1 paragraph 9.0.5 as follows:

Above: Figure 2 Chamber soak pit.

32

December 2017/January 2018

Vstor = Rc - Vsoak where

Rc = run-off from catchment to soak pit in 1 hour (m3)

Vsoak = volume disposed of by soakage in 1 hour (m3)

and

Rc = 10 CIA

where

C = run-off coefficient (from E1/VM1 Table 1)

I = rainfall intensity (mm/hr) based on 1 hour duration of an event having a 10% probability of occurring annually

A = area (in hectares) of the catchment

where

Asp = area of the base of the soak pit (m2)

Sr = soakage rate (mm/hr).

discharging to the soak pit and Vsoak = AspSr/1000

Rainfall intensity (I) is based on rainfall with a 1 hour duration and a 10% probability of occurring annually. Information about rainfall intensity can be obtained from local rainfall intensity curves produced by the building consent authority or from rainfall frequency duration information from NIWA.

Ways to reduce soakage capacity The effectiveness of soak pits can be increased by storing or retaining stormwater on site with water storage tanks, areas planted in trees and shrubs that soak up water and irrigated areas.

When these are incorporated, the soakage capacity of a soak pit may be reduced if supporting calculations are provided.

Check for other council requirements Soak pits should be located above the winter water table and not on a stormwater secondary flow path.

Most local authorities have specific requirements for soak pits, such as minimum distances from boundaries and existing buildings. These should be checked before making a soak pit application.

Soak pit maintenance needed annually Soak pits require maintenance to prevent them becoming blocked with silt, vegetation or other matter that may cause flooding problems.

Maintenance and cleaning should be done annually by a company that specialises in the cleaning and maintenance of soak pits.

Calculate soakage rate and storage Use the E1/VM1 formula: Vstor = Rc - Vsoak Step 1: Get the soakage rate from the percolation test Assume that, from a percolation test, the soakage rate (Sr) has

been calculated at 300mm/hour. Then, where the soakage rate is: • more than 500mm/hour, soakage rather than storage is the main factor in the design of the soak pit

•

significantly less than 500mm/hour, storage becomes the main factor in the design around 500mm/hour, the soak pit design must consider both soakage and storage to make sure that water will

•

disperse into the ground before it overflows.

Step 2: Assess the stormwater catchment volume (Rc) Use the formula: Rc = 10 CIA Assume:

Roof area = 200m2

Paved area = 50m2

Total run-off area (A) = 250m2

(0.025 ha)

Use run-off coefficient (C) = 0.9 (from E1/VM1 Table 1 for hard surfaces) Rain intensity (I) = 70mm/hour Rc

= 10 CIA

Rc

= 10 × 0.9 × 70 × 0.025

Rc

= 15.75m3

Step 3: Calculate the volume of water disposed by soakage (Vsoak) Use the formula: Vsoak = AspSr/1000 Assume:

Soak pit size = 5.0m × 3.0m × 2.0m

= 30m3

The soak pit is to be a hole filled with rocks. (When calculating the size of a soak pit, the volume of water storage available for a rock-filled hole is 0.38 times the volume of the hole.)

So:

Vstor = 0.38 × 30m3 = 11.4m3

Calculate:

Asp (area of base of soak pit) = 5.0m × 3.0m = 15m2

Vsoak = 15 × 300/1000

Vsoak = 4.5m3

Step 4: Calculate storage volume required Use the formula: Vstor = Rc - Vsoak

Vstor = 15.75m3 - 4.5m³ = 11.25m3

11.25m3 ≤ 11.4m3 so soak pit sizing is OK.

Updating AS/NZS 3500 REVIEWING A STANDARD is no simple task. It takes a great deal of time, effort and input by many people. For Rotorua plumbing business owner Jon Lewis, it has involved meetings with Standards New Zealand and the Ministry of Business, Innovation and Employment (MBIE) plus several trips to Sydney as part of the joint WS-014 Technical Committee assigned to the project.

Jon is one of only two installers on the committee, which also comprises manufacturers, suppliers, water utilities and government regulators from both sides of the Tasman.

AS/NZS 3500 is a weighty document. Parts 0 to 4 of the series are included in the review, which excludes Part 5. The public comment period for Part 3 closed in May, while Parts 1, 2 and 4 were out for comment through Standards Australia until 7 December. Jon is now due to return to Sydney where the committee will consider all comments received and redraft if necessary.

The revision of Part 2, Sanitary plumbing and drainage, includes changes to align the Standard with the Plumbing Code of Australia, which sits within Australia’s National Construction Code.

The revisions of Parts 1 and 4, Water services and Heated water services, aim to update requirements relating to backflow prevention, plastic pipes in direct sunlight, thermostatically controlled taps, circulatory heated water and non-drinking water, and to clarify jointing methods.

“The whole Standard is relevant to New Zealand, so we’ve got to be there and we’ve got to be involved,” says Jon. He admits

All Standards are reviewed from time to time, and it’s currently the turn of AS/NZS 3500.

Above: Parts 0 to 4 of AS/NZS 3500 are being reviewed.

that communication with Standards New Zealand and MBIE has been challenging, and he would like to see more interest from the government in aligning Building Code G12 Water Supplies with the revised AS/NZS 3500.

“Master Plumbers is the only installer organisation in New Zealand represented on the committee,” says CEO Greg Wallace. “For Jon it means time away from work and family, but we must play our part in the creation and review of Standards for our industry in New Zealand.”

Master Plumbers supports members on other Standards committees, too. Jon, for example, is also part of the WS-023 Technical Committee that is reviewing backflow prevention Standard AS/NZS 2845. ■

Amendments to AS/NZS 3500.2:2015 In its latest InfoBrief newsletter, the PGDB gave the following reminder of amendments to AS/NZS 3500.2:2015, published in June.

“The specific clauses affected are 4.9.1, 4.9.2, 4.9.3, 5.3, 6.5.2.3, 6.5.2.4, 6.5.2.5, 6.5.2.6, figures 4.9.2, 4.10 and 6.5.2.1.

“Many of the changes have affected the general design requirements for sanitary plumbing. Specifically, there has been a move away from the use of sweep junctions (e.g. swept 88° junctions) to connect in combined discharge pipes.

“Two areas that will have a noticeable effect on plumbers are with junctions in graded pipes and junctions installed in a vertical plane.

“With regards to junctions in graded pipes, pre-amendment 6.5.2.3 outlined that ‘Junctions (whether equal or unequal) shall be either 45° or sweep type,’ however, post-amendment 6.5.2.3 states ‘Junctions (whether equal or unequal) shall be 45°.’

“With regards to junctions installed in a vertical plane, pre-

34

December 2017/January 2018

amendment 6.5.2.6 outlined that ‘Sweep and 45° junctions may be installed in the vertical plane for the connection of a single discharge pipe....’

“However, post-amendment 6.5.2.6 states ‘45° junctions shall be installed in the vertical plane for the connection of a single discharge pipe and common discharge pipe.’

“A noticeable change in drainage systems is in figure 4.10 which shows a typical vertical jump-up from the main drain to graded branches. Pre-amendment this figure displays a sweep 88° junction and post-amendment it displays a 45° junction.

“The move to 45° junctions and away from sweep junctions will be an improvement to the system as it improves airflow in the discharge pipes resulting in a lower chance of blockage.

Pipe penetration through roof

NUTS & BOLTS

Small pipe penetrations in roofs are typically flashed using proprietary EPDM boot flashings. By Alide Elkink.

FOR PROFILED METAL roofing, E2/AS1 permits use of boot flashings where: • the maximum roof pitch is 45° • the minimum pitch is 10° if the base of the flange covers one or more complete troughs • the pipe diameter is no more than 85mm • they are installed on the diagonal so water will flow around the flashing.

The boot flashings must be dressed, sealed and fixed to the roof profile (see Figure 1).

soaker flashing dressed to the tile profile, or a lead sleeve taken 100mm up the pipe and soldered to a lead flashing that is dressed to the roof tile profile 150mm all around and carried up to the top edge of the tile – E2/ AS1 Figure 29.

For larger framed penetrations, refer to E2/AS1 Figure 31 or use a proprietary boot flashing designed for flues. These are outside that scope of E2/AS1 and must be submitted for consent with supporting information as an alternative method.

A preferable option is to carry the soaker flashing up the roof to a ridge flashing (see Figure 2) rather than the details shown in E2/AS1: Figures 54 and 55. The NZ Metal Roof and Wall Cladding Code of Practice recommends a maximum length for a soaker flashing of 1.5m to a ridge. ■ •

Figure 1: Pipe flashing.

For larger penetrations, flashing is using: a soaker flashing with an EPDM boot flashing for penetrations up to 500mm – E2/AS1 Figure 54 • a soaker type flashing (for penetrations up to 1200mm) – E2/AS1 Figure 55.

For masonry tiles, a pipe penetration may be flashed using: • an EPDM boot flashing fitted to an integral malleable •

MEPS requirements for HWC Rinnai explains why electric hot water cylinders must comply with MEPS in New Zealand.

THE ELECTRIC HOT water cylinder is one of the appliances with a MEPS requirement in New Zealand. MEPS, or Minimum Energy Performance Standards, is a series of energy-use standards for appliances, which looks to minimise appliance energy consumption.

Any cylinder from 6.5 to 630L needs to meet MEPS requirements—which covers the vast majority of domestic HWC in NZ.

conducting MEPS testing, Rinnai felt the rigorous accreditation process would result in a very robust test process, giving quality results Rinnai and its customers could rely on.

The accreditation process includes an independent assessment by a process expert as well as a full process and documentary check and an assessment of staff knowledge and suitability. The Rinnai laboratory is the only HWC manufacturers’ test facility to have IANZ accreditation in NZ.

HWC manufacturer compliance

New cylinder technology

For manufacturers such as Rinnai, it is important that we are able to test and ensure compliance with MEPS. To enable us to do this, we have built a HWC test laboratory, featuring stateof-the-art temperature measurement and recording systems, as well as highly accurate calibration equipment. The lab is able to perform tests to any of the NZ test methods.

To ensure the lab follows best practice and can give quality results, we have gained IANZ accreditation for the testing we undertake. While IANZ accreditation is not essential for labs

Rinnai has been working in the areas of cylinder insulation and standing heat loss determination to bring to market a range of new hot water cylinders suitable for both indoor and outdoor installation.

The cylinders feature a Colorsteel corrosion resistant outer case and are electrically approved for outdoor fitment. Rinnai has also worked on a design that meets MEPS requirements while allowing ease of installation in domestic hot water cupboards by keeping the outer case diameter under 500mm.

Above: Rinnai has built its own hot water cylinder test laboratory where IANZ-accredited testing is carried out to ensure MEPS compliance.

36

December 2017/January 2018

We have worked with the leading insulation foam suppliers in NZ and Australia to determine a new formulation of insulation foam that allows us to meet the combined challenge of a practical outside diameter on the cylinder for ease of installation by the tradesperson, along with meeting MEPS requirements to ensure the cylinder minimises heat loss.

The foam formulation also has a low Global Warming Potential index. This means its overall contribution to climate change and ozone depletion is minimal.

NZBC H1 Energy Efficiency EECA calculates that up to 30 percent of the average household annual electricity bill can be apportioned to hot water production, which shows how much impact energy-efficient hot water cylinders have on domestic power bills and overall energy use.

MEPS is set in New Zealand legislation by the Energy Efficiency (Energy using Products) Regulations 2002, which set out requirements for appliance suppliers to follow. For specifiers and installers, MEPS for HWC becomes a consideration in the NZ Building Code (NZBC)—specifically section 5.0 of H1/AS1.

NZBC H1 covers energy efficiency, and in many building consents H1/AS1 will be the method cited for compliance. Section 5.0 is quite specific in that it says: “Electric Storage Water heaters that do not comply with NZ MEPS do not comply with this solution.” It is important to note that MEPS requirements for New Zealand are different from those for Australia.

MEPS for Australia and NZ are set out in electric water heater Standard AS/NZS 4692.2:2005. This details the test methods used to determine if an HWC meets the MEPS requirements.

In simple terms, the test looks at how much energy is needed to maintain a cylinder at a fixed temperature over a given length of time with no water flow in or out of the cylinder. The amount of energy needed to maintain this temperature is directly related to the amount of energy being lost to the outside. This energy loss is known as standing heat loss.

Causes of standing heat loss Several factors can influence standing heat loss, which is measured in Kilowatt-hours (kWh) per 24 hours. Examples include: • level of insulation on the tank • type of insulation used • cylinder surface area • number of ports • temperature of the water inside the cylinder.

Using AS/NZS 4692.2, a typical NZ specification mains pressure 180L cylinder has to perform better than 1.76kWh/24h.

A cylinder complying with Australian MEPS of broadly the same specification has to perform better than 2.02 kWh/24h. Over a year that’s a difference of around 95kWh. So you can see why the NZBC mandates hot water cylinders with NZ MEPS must be used. ■

Our latest round up of gasfitting news.

5601 under review

Ongoing reviews are underway for parts 1 and 2 of gas installations Standard AS/NZS 5601:2013, which are cited in the Gas (Safety and Measurement) Regulations.

The JAS-ANZ AG-006 committee reviewing the Standard comprises around 20 members who meet bi-monthly to discuss gas installation and appliance matters for the New Zealand and Australian markets. It includes technical regulators from both countries, with New Zealand contributing through Energy Safety.

Master Plumbers Board Director John DeBernardo is among a total of three NZ members of the group—the others being Keith Rogers of Energy Safety and Peter Gilbert of the LPG Association. John gave a summary of the review at the Master Plumbers half-yearly meeting in October.

Part 1: General installations One key proposal for change is to prohibit the use of composite PEX gas pipe outside above ground. This, says John, is as a result of the destruction of this type of pipe during the recent Australian bush fires.

The pipe sizing tables in Appendix F are also being reviewed,

with the view that some may take an overly conservative approach. “For example, when sizing pipes for a multi-storey building, the load is calculated to allow for every appliance to be running at the same time, which possibly results in oversized pipes,” he said.

There are also plans to increase the requirements for fireresistant construction and facing materials used in commercial kitchens and for combustible surfaces in domestic kitchens.

Part 2: LP gas installations in caravans and boats Key proposals for change are: • •

Revising the clearances around LPG cylinders on caravans and mobile vehicles.

Introducing a standard metallic compliance plate for new marine and mobile applications.

There is no desire to stop manufacturing innovation and quality imports, explained John, but there are safety concerns around the quantity and location of LPG cylinder storage in some mobile installations—particularly caravans and trucks.

Gas appliances in imported caravans and motorhomes Energy Safety is reminding importers of caravans and motorhomes that they can’t be sold without certified or endorsed gas appliances, even if the importer tells the buyer that it needs doing.

Anyone who sells something that isn’t certified when it needs to be may be committing an offence, it says.

“All gas appliances and installations have to be safe.

Certification and endorsement provide means of demonstrating safety. Regulation 44(3) of the Gas (Safety and Measurement) Regulations 2010 states: Every person who supplies or intends to supply an imported gas installation to a retailer or consumer must, before supplying the gas installation, ensure that it complies with the requirements of section 2 of whichever of the following applies: (a) AS/NZS 5601.1; or (b) AS/NZS 5601.2.

“This Regulation applies to anyone who imports a gas installation and supplies it to another person (which includes sale). It doesn’t apply to someone who imports an installation

Gasfitting infringement

Energy Safety recently issued an infringement notice to a gasfitter who issued a gasfitting Certificate of Compliance (CoC) indicating that the work performed complied with AS/ NZS 5601.1 when in fact the work did not comply.

“Gasfitters and electrical workers have to ensure that the gasfitting or prescribed electrical work they do complies with the relevant provisions of the Gas (Safety and Measurement)

38

December 2017/January 2018

for their own use unless or until they subsequently supply it to another person.

“The Regulation is met by obtaining verification that the essential requirements in section 2 of AS/NZS 5601.2 have been met. A certificate of verification using the methodology of NZS 5255:2014 Safety verification of existing gas installations would do that.

“This isn’t the only way. For example, if the caravan or motorhome is imported from Australia it is likely to have been constructed to AS/NZS 5601.2 in the first place and if the importer has the compliance documentation that would also meet Regulation 44 provided the installation is not unsafe.

“Regulation 54 applies to appliances in imported installations. They have to be certified or alternatively be endorsed in accordance with regulation 57 (endorsement may replace certification for certain appliances and fittings) before they are offered for sale.” ■

Regulations or the Electricity (Safety) Regulations 2010,” says Energy Safety.

“Each of these regulations cites an installation standard that contains a means of compliance that installation should comply with. Gasfitters and electrical workers who undertake installation work need to ensure they understand and follow the means of compliance for the work undertaken.”

INDUSTRY TALK

A super weekend Three lucky plumbers and their families got up close to the action at the ITM Auckland SuperSprint, thanks to Rheem.

The winners of the Rheem Super Weekend competition with Rheem and Master Plumbers were treated to a VIP experience at Pukekohe Park Raceway on 4 and 5 November for the New Zealand round of the Virgin Australia Supercars Championship.

The special weekend, which included travel and accommodation, began with a behind-the-scenes tour of the pits and a chance to meet Shell V-Power Team Racing stars Fabian Coulthard and Scott McLaughlin.

A grid walk moments before the race gave the Rheem Super Weekend winners a chance to check out the teams’ last-minute prep, before watching the Supercars from a VIP suite in prime position above the pits.

Steve O’Connor of Whakatane’s Eastern Bay Plumbing took his 90-year-old dad, Ray, a retired mechanic, to enjoy the unforgettable weekend. “It was, for me, extra special that I could take my father. He had a ball,” says Steve.

Kyle and Rhonda Smythe, from Auckland’s Premium Plumbing & Gasfitting, said they were blown away by their “amazing” experience, while Vicki and Peter Rine of Marton’s Cobham Plumbing & Drainlaying took their son Daniel with them for the once-in-a-lifetime chance to get close to V8 racing’s best drivers.

It was an action-packed weekend as Coulthard flipped his Ford Falcon on Saturday, before a near-miraculous car rebuild overnight put him back on the track for Sunday’s racing. He stormed back for fifth while McLaughlin came in second, keeping his hopes of a championship victory alive.

Rheem is a major sponsor of the Shell V-Power Racing Team, and was thrilled to share this year’s ITM Auckland SuperSprint with its loyal customers. The winners were chosen from entrants who had recently purchased a Rheem Gas Continuous Flow Water Heater.

“We’re proud to support these legends of V8 Supercars, and the ITM Auckland SuperSprint is a great opportunity for our clients to enjoy the thrill of their success,” says Brian McFarlane, Marketing Manager at Rheem New Zealand.

Top talents

It’s been another year of high achievers in the Certifying exams, says the PGDB. Each year, the Plumbers, Gasfitters and Drainlayers Board (PGDB) present Merit of Excellence Awards to top performers in the Plumbing, Gasfitting and Drainlaying Certifying Exams.

In 2017, they were awarded to Michael Williams of Taupo, Warren Shervey of Wellington and Sven Hogenesch of Hawkes Bay. “It is top performers such as these who are contributors to the growth of the industry and lead by example in raising the profile and ensuring the highest of professional standards within the trades,” said PGDB Chair Peter Jackson.

Michael Williams started his plumbing, gasfitting and drainlaying apprenticeship in 2005. He completed his Plumbing and Gasfitting National Certificates in 2010, achieving that year’s highest mark for plumbing, and registered as a Tradesman Plumber the following year.

Michael went on to pass the Certifying Plumber exam in June 2016, scoring 86.5 marks, and became registered as a Certifying Plumber three months later.

Warren Shervey started his plumbing and gasfitting apprenticeship in the 1990s, and went on to become a Certifying Plumber and Gasfitter in 2004.

He then became registered as a Tradesman Drainlayer in 2016, after having completed his National Certificate and passed the Tradesman Drainlayer exam.

Warren sat his Certifying Drainlayer exam in November 2016, scoring 94 marks. He will be eligible for registration in 24 months.

Sven Hogenesch started his training in plumbing and gasfitting in 2008, adding drainlaying in 2010. He registered as a Tradesman Plumber and Gasfitter in 2012, having completed his

Sven passed his Tradesman Drainlayer exam in 2015 and became registered the following year. He then sat his Certifying Plumber and Gasfitter exams in 2016, scoring 94.5 marks in gasfitting.

He became registered as a Certifying Plumber in 2017 and is eligible for registration as a Certifying Gasfitter.

Makeover at MBIE

A recent MBIE review showed that ‘Building System Performance’ was the regulatory system most in need of improved performance.

As a result of the review, Building System Performance (BSP) is being ‘transformed’, according to the Ministry of Business, Innovation and Employment (MBIE).

A new BSP structure took effect on 2 October, with new General Manager Anna Butler at the helm. The aim is to help ensure a more joined up approach, with a ‘whole of system’ view of building and construction.

“The work MBIE and BSP does matters,” says Anna. “Building and construction make a significant contribution to our nation’s economy and social wellbeing. These changes will effectively shape the building regulatory system to meet New Zealand’s current and future needs.”

The changes have seen the addition of 22 more positions across MBIE’s building services.

BSP is also streamlining its work programme to focus resources on the big issues. “We’re building our culture and capability so we can deliver a higher-performing building system, directed by strategic goals and a good understanding of the sector,” says Anna.

“We know we can’t do this alone—MBIE will collaborate with our industry partners to provide quality policy advice and guidance. The whole sector has a role to play in lifting performance, embracing innovation and moving forward.”

As part of the change, the Determinations team and a new Building System Assurance team have become part of the Market Services group within MBIE. This group already houses the LBP and Weathertight Services teams.

Sam’s speak

This edition, Sam Tyson reflects on the importance of being professional.

Disaster struck with a job we were working on recently. We were installing a radiator system into a new-build home and were at commissioning stage. The homeowners were set to move in within the next two weeks. We had balanced the radiators and left the system under pressure with the autofill hooked up to work out any air.

The homeowner wanted to be able to turn the system on when winter arrived without issues.

Overnight, a pipe connected to a fitting by the boiler gave way. The boiler was in the ceiling space on the second level. Water poured down through the ceiling, flooding the upper level which happened to be a concrete slab. This caused water to travel mainly to the outer edge and cascade down into the outside wall cavities, soaking and swelling the plasterboard and wood. There was damage to walls, ceilings, carpet, light fittings… you name it.

As you can imagine the homeowners were devastated when they discovered the flooding the next morning. It had taken a year to get to the point where they were so close to moving in.

On finding out, we immediately kicked into action by sending one of our tradesmen out to stop the water flow and isolate the system. We contacted our insurance company and I visited the

homeowners that day to discuss what had happened and to present them with a voucher for dinner, bed and breakfast at one of our local boutique hotels.

This in no way compensated for what had happened, but the gesture was appreciated.

In talking with the homeowner, he told me they had a choice of three plumbing and heating businesses to go with when deciding on their heating system, and chose us because of our professional approach.

We weren’t the cheapest but we presented ourselves as competent, trustworthy, courteous and respectful—and, right now, we were demonstrating accountability.

The homeowner, a retired carpenter, said of all the tradesmen on site, our guys worked diligently and competently without distraction, and he had told our lead tradesman how pleased he was with his work the day before disaster struck.

We don’t know whether it was a workmanship issue or a faulty fitting, but at no point have we blamed, shamed or justified what has happened.

We have simply taken responsibility to put it right, because that’s what a professional business does.

Public loos feel the strain…

Laser Group’s Scott Carr is calling for increased investment in water sanitation to keep up with population and tourism growth.

With New Zealand’s growing population and increasing numbers of tourists visiting our country, the government needs to ensure that our waste management facilities and practices meet demand, says Laser Group New Zealand General Manager Scott Carr.

New Zealand’s tourism market is booming, with more than 3.4 million tourists arriving on our shores in 2016. The influx of tourists is beginning to place a strain on public infrastructure around the country, says Scott—particularly on public toilets.

With ageing infrastructure, the amount of public amenities in several of New Zealand’s tourist hotspots are struggling to keep up with tourist numbers, leading to reports of defecation in public parks and overflowing septic tanks.

“It’s important that the organisations responsible for waste management stay at the forefront of technology and community needs, to keep the environment and water quality of New Zealand pristine,” he says.

“Whilst plumbing isn’t all about waste management, it is important to take the time to appreciate the role our plumbers 42

Workout for water

UNICEF partnered with Les Mills in November for a global fundraiser.

The worldwide Move The World fundraising event was linked to UNICEF’s celebration of children on World Children’s Day (20 November). UNICEF partnered with fitness company Les Mills International in creating this global fundraising campaign and one-day fitness activation to help children and their families in some of the world’s poorest nations to gain access to safe water, healthcare and food.

This year’s event focused on Workout for Water, with Les Mills’ instructors and gyms asked to fundraise $414 USD—the

cost of a well in East Africa that could bring clean drinking water to an entire community. On 18 November, in gyms and fitness clubs around the world, instructors led special group fitness classes with participants asked to make a donation to the cause.

Each workout included a challenge representing an East African child’s journey to collect clean water—for example, walking 3.7 miles (8,000 steps) whilst carrying water cans weighing up to 20kg.

Warning for solar retailer

A solar panel retailer has been issued a warning by the Commerce Commission.

Solar panel retailer New Zealand Home Services Ltd (NZHS) is likely to have breached the Fair Trading Act, according to the Commerce Commission, by making unsubstantiated representations about the financial benefits of solar panel installation on its website and in its sales presentations.

“It is important for traders to properly substantiate claims which cannot easily be verified by the consumer,” said the Commission’s Head of Investigations, Ritchie Hutton. “Solar panel installation requires significant up-front cost and in our view NZHS made claims about the financial benefits of installing solar systems without sufficiently backing up those claims in the

New Zealand market.”

The Commission asked NZHS to provide materials to substantiate its claims. “In our view the materials provided were of varying degrees of reliability, were from overseas sources not relevant to the representations made about the New Zealand market, or were created or compiled after the representations were made,” he said. The substantiation provision of the FTA requires a trade to have reasonable grounds for making a representation at the time it was made.

NZHS has since removed the representations from its website and sales presentations.

Melbourne Cup Day

The Auckland Master Plumbers enjoyed a day at the races in November.

Plumbers and their partners turned out in all their finery for a private marquee Melbourne Cup Day event at the Ellerslie Race Course in November. Also attending were representatives from the 14 Master Plumbers’ Business Partners kindly sponsoring the event.

The day was hosted by the Auckland Master Plumbers, and President Dale Lovell kept his promise of a fine, sunny afternoon for the assembled crowd of 120 people.

Guests mixed and mingled at the 15 tables and some took a flutter on the horses, with Geoff Miles of Caroma particularly pleased with his $1,600 win on a $6 bet.

Best dressed male and female prizes were also given on the day—Milan Kumar of simPRO and Jo Jeffries of Jeffries Plumbing scoring the prize vouchers for their race day outfits.

Above: The best-dressed prize winners.

A costly outbreak

The Havelock North water contamination event cost around $21 million, according to a Ministry of Health report.

The Stage 2 Inquiry hearings into the Havelock North water contamination event were completed in August, with the final report due on 8 December, as this edition of NZ Plumber went to print.

In an article in Water Journal magazine, Water New Zealand Technical Manager Noel Roberts said the Inquiry “heard evidence of the lack of compliance with the NZ Drinking Water Standards, and expressed dismay at the lack of enforcement of the regulations by the Ministry [of Health] over the past 10 years.”

According to the article, hearing panel members showed “considerable frustration” at the Ministry’s lack of leadership, and it was being expected to “get on and make changes” ahead of the December deadline.

In September, the Ministry of Health released an independent report on the economic costs of the Havelock North outbreak.

According to Water New Zealand, the report states the outbreak has cost around $21 million, including an estimated cost of $12.4m for ‘household inconvenience’, such as boiling water and taking time off normal activities.

Water New Zealand CEO John Pfahlert says it cost just $1m to install a water treatment plant for the Havelock North

community following the outbreak, showing that effective water treatment makes economic sense. “Twenty-one million dollars is a significant amount of money, especially compared to the cost of water treatment,” he says. “But we also know that water contamination outbreaks have a big human toll.”

The outbreak could have been even worse if the campylobacter strain had been slightly different, he says. “In that case we could have been looking at a way bigger calamity including a scenario of many more deaths. Whatever way you look at it, water treatment is a no brainer and water suppliers need to be very aware that outbreaks are way more costly than preventative treatment.”

The Office of the Auditor-General announced in October that it is to explore New Zealand water management system in its 2017/18 work programme, partly as a result of the Havelock North drinking-water contamination and Edgecumbe flooding issues. “What we bring to the topic is the independence that enables us to look at the water management system as a whole— across central and local government and beyond political cycles.”

When the work is completed, the Office will highlight any improvements needed.

Measuring construction costs NZIQS has signed up to the new international construction measurement standards.

The New Zealand Institute of Quantity Surveyors has signed up to the new International Construction Measurement Standards (ICMS), which provides consistency in classifying, defining, measuring, analysing and presenting construction industry costs.

By providing a global framework for measuring, costing and reporting, ICMS enables governments and investors to compare construction costs like with like.

Previously there was no universal standard and, internationally, the construction industry used different methods of measurements. Nor was there any commonality in terms of costs and construction reporting.

The ICMS coalition was formed to address these issues, and the New Zealand Institute of Quantity Surveyors joined as a trustee member 18 months ago.

NZIQS President Barry Calvert says New Zealand is pleased that ICMS is very similar to the standard already in place here.

“NZIQS now has training in place for their members to become familiar with the ICMS format and we will be encouraging quantity surveyors to use it for both public and private sector projects going forward.

“With ICMS in place, construction agencies and their clients will be able to compare the cost of a building in New Zealand to

any other country in the world and know that the costs and the standards of the building will be equal.”

Another New Zealand member of the coalition, registered valuer John Darroch, says the ICMS means the public will have more confidence in costs that are quoted to them.

“ICMS will standardise how construction costs are reported.

This will assist in evaluating properties and the public will know they are receiving accurate information.”

SAFETY FIRST

Hazardous substance changes are here

WorkSafe explains the new focus on hazardous substance safety.

HAZARDOUS SUBSTANCES ARE widely used across New Zealand workplaces, so it’s important to know the risks and how to protect people from harm.

On 1 December, the Health and Safety at Work (Hazardous Substances) Regulations 2017 came into force. They apply to all workplaces that manufacture, use, handle and store hazardous substances.

One in three businesses work with hazardous substances in New Zealand and that includes tradespeople. Common hazardous substances are fuels and LPG, acids, cleaning solutions, paints, glues and chlorine.

“Used safely, hazardous substances can contribute to the nation’s economic growth and prosperity,” says WorkSafe General Manager Operations and Specialist Services, Brett Murray. “But they also pose real risks to the people working with or around them, including explosion, fire, and serious health issues.”

46

December 2017/January 2018

Work-related health risks It is estimated that New Zealand workers are 10 times more likely to die from work-related health risks, such as hazardous substances, than workplace safety incidents, he says. However, despite this harm, there can be more complacency about the dangers of hazardous substances than other workplace risks.

“The harm from inhaling toxic vapours or contact with some substances is often unseen. Workers may be unaware they are being exposed, and the effects of exposure may not be discovered for many years.

“The regulations are aimed at reducing the harm from hazardous substances in the workplace and will increase the focus on their safe management. They bring an expectation on everyone working with them to know what those substances are, the risks they pose and how to manage those risks.”

SAFETY FIRST

What’s different?

This is not about wholesale change. The rules for work-related activities involving hazardous substances are moving from the Hazardous Substances and New Organisms (HSNO) Act to the Health and Safety at Work Act (HSWA).

Many of the existing requirements continue under the new regulations, so if your business is complying now, there may not be much more you have to do. However, there are key changes that will help ensure you, as the person in charge, are doing your duty to protect people from harm.

The starting point is to identify the risks in your workplace.

Make a list of the hazardous substances on site, the quantities and where they are stored. Then read the safety data sheets (SDS) to understand the risks they pose, how to use and store them safely and what to do if there is a spill or you are exposed to them. A SDS will be required for each substance.

“You will also need to keep an inventory of your hazardous substances, and the simplest way to do this is to use the Hazardous Substances Calculator,” says Brett Murray (see box below).

The calculator will help you work out the safety measures (or controls) you need to put in place to keep people safe. This includes general requirements, such as labelling, packaging and ensuring workers have sufficient instruction and supervision, as well as any additional measures triggered by certain substances or quantities.

“Some highly hazardous substances will require a certified handler, while certain quantities of some substances may mean you need to engage a compliance certifier to issue a location compliance certificate. So, as well as reducing risk, keeping your substances to a minimum can help reduce the costs to your operation.

“That’s why you should first look at whether you can remove any products, reduce the amount, or replace them with a safer alternative.”

It is important to note that the required controls may not be enough to protect people from harm, and you must remove or reduce any remaining risks. This can include installing safety measures, such as extractor fans or using automated enclosed areas to conduct hazardous work.

“Personal protective equipment may also be necessary, but should be the final step after implementing other measures. And remember, even the most safety-conscious business can have an accident. Make sure you have an emergency plan in place, including who to contact and who is responsible for what.” ■

You must have a Safety Data Sheet for all hazardous substances in your workplace, regardless of the quantity you hold (some exceptions apply).

3 Information, instruction, training and supervision The Health and Safety at Work (Hazardous Substances) Regulations have specific requirements around providing information, instruction, supervision and training to make sure workers know how to safely use, handle and store the hazardous substances in their workplace.

4 Emergency preparation You should be managing your risks to avoid an emergency, but it’s equally important to plan for one. The Regulations set out specific requirements for this. This includes understanding procedures to deal with emergencies.

5 Labelling containers of hazardous substances (including hazardous waste) There are new requirements for making sure that hazardous substance containers in the workplace are labelled, including process vessels—as well as maintaining the labels on hazardous substances supplied to you.

6 Signs These continue to be an important part of hazardous substances management, as they warn other people in the workplace and emergency services that hazardous substances are on site.

7 Focus on risk assessment, and elimination or minimisation It is important to manage the risks associated with hazardous substances and to review what you have in place to keep people healthy and safe. Eliminate risks if reasonably practicable and minimise risk where elimination is not possible.

The new Regulations come into force on 1 December but there are some later commencement dates and transitional arrangements that are summarised on the WorkSafe website (see box on the left).

SAFETY FIRST

H&S: are you onto it?

The ‘new’ workplace health and safety legislation has been in place for nearly two years. Doing enough? Cecilia Milne of Duncan Cotterill provides a point-by-point refresher.

1. Plumbers, gasfitters and drainlayers work in a high risk sector. Ensuring the health and safety of everyone on and around your worksite, including workers, clients and members of the public, is essential.

2. The Health and Safety at Work Act 2015 (HSWA) is New Zealand’s main workplace health and safety law. The HWSA was introduced as part of an overhaul of New Zealand’s health and safety regime, after an independent taskforce concluded that Kiwi attitudes to health and safety are too laid-back. If there’s one take-away message from this article, it’s that a ‘she’ll be right’ approach just won’t cut it any more.

3. All of us, at every level of an organisation, should be adopting a proactive, rather than a passive or reactive, approach to workplace health and safety. Organisations must create a culture where staff and management ‘walk the talk’. Failure to do so can result in injury or death, and risk prosecution, hefty fines and imprisonment.

What are my obligations as a plumbing business or organisation?

4. The primary duty under the HSWA is on the ‘Person Conducting a Business or Undertaking’ (PCBU). The definition of PCBU covers all types of modern working arrangements, including a plumbing organisation (be it a company, partnership or other entity) or an individual plumber operating as a sole trader or a self-employed person. PCBUs that work together—such as multiple subcontractors working together on a construction site— will have overlapping duties.

5. A PCBU must ensure health and safety, so far as is ‘reasonably practicable’, of its own workers, as well as other workers whose activities are influenced or directed by the PCBU. It must also protect others who might be put at risk from the conduct of the business or undertaking, such as visitors or the public.

What does this mean in practice?

6. Each PCBU must work together with its officers and workers (see points 8 & 9) to identify potential hazards or risks and take reasonable steps to eliminate or minimise risk and ensure health and safety. Such steps will vary according to the

a ‘she’ll be right’ approach just won’t cut it any more 48

industry, organisation and worksite, but will include at least a duty, so far as is reasonably practicable, to: Eliminate or minimise risks Provide a safe work environment Provide safe equipment Ensure suitable procedures Provide appropriate training, induction and supervision Monitor conditions at the workplace.

7. The following table identifies some areas that may be relevant to plumbers, gasfitters and drainlayers and suggests non-exhaustive examples to assist readers in thinking about the sort of practical steps you might take in your business.

What are my obligations as an officer or worker?

8. ‘Workers’ and ‘others’ must take reasonable care for their own and others’ health and safety, and comply with the PCBU’s policies, procedures and instructions. A ‘worker’ will include employees, contractors, subcontractors, temporary or labour

SAFETY FIRST Area

Examples of practical steps

Training and worker participation

• Are staff properly supervised and given clear instructions?

• Are workers trained, competent and fit to do the job safely and without putting their own or others’ health and safety at risk?

• Are workers involved in ongoing discussions about health and safety issues and given opportunities to participate in improving health and safety?

Site and services

• Is access safe, tidy, and well lit with edges/holes marked?

• Have all necessary services been provided and steps taken to prevent harm from them (eg, gas or electricity mains)?

• Are tools, leads and cables appropriate and in good condition?

• Is the worksite fenced off from the public, with clear signage and secured overnight?

Working at height

• Where persons are working at height—for example, on scaffolds, ladders or roof work—are they and those around them protected from harm/falls/dropped equipment?

Moving material

• Have steps been taken to avoid harm to persons involved in manual handling of heavy materials or the loading and unloading of goods?

• Are any excavations being carried out in a safe manner?

Working with vehicles and machinery

• Are vehicles and plant in good condition, and used or driven safely and properly with appropriate training?

• Are the right tools and machinery being used for the job, with the right training and maintenance, and with all dangerous parts guarded?

Critical health risks

• Are all potentially hazardous substances identified and controlled, and used only with appropriate training?

• Are workers protected from noise?

• Is suitable personal protective equipment provided and used?

Worker wellbeing

• Are workloads suitable and are there steps in place to address the risk of fatigue?

• Is there policy and procedure in place to manage alcohol and drug related hazards?

Emergency situations • Are there procedures and training to deal with emergencies and fire?

Working off-site

• Is health and safety ensured when staff are working off-site?

hire workers, apprentices or trainees and volunteer workers (for example, someone on work experience).

9. ‘Officers’—individuals in the position of a director in a company, a partner in a partnership, or a comparable position with significant influence over the management of the business—must take reasonable steps to plan, deliver, monitor and review the PBCU’s management of health and safety risks.

10. The duty on officers is a personal one—it can’t be delegated to a health and safety manager or consultant.

The implications of non-compliance

11. By way of example, successful prosecutions under the previous legislation have included the following situations: • Company specialising in plumbing, gasfitting and drainlaying services: The employee was working on a roof and was attempting to untangle a hose when he stepped forward onto a skylight and fell six metres into the workshop below, suffering a broken clavicle.

• Company involved in installing effluent management systems and tanks: The victim was working in a deep excavated trench that had not been protected from collapse, when the trench face collapsed and buried him.

The victim died at the scene.

• Company carrying out general electrical and refrigeration work: An employee came into contact with live terminals while carrying out electrical work on a refrigeration unit in the roof space of a chiller room and was fatally electrocuted.

12. Penalties under the HSWA depend on the offence and what type of duty holder the offender is, as well as the seriousness of the conduct.

13. The maximum penalties for the most serious health and safety duty offences are: • For an individual who is not a PCBU or an officer (ie, a worker or other person): five years in prison or a $300,000 fine, or both • For an officer or an individual who is a PCBU (eg, a sole operator or self-employed individual PCBU): five years in prison or $600,000 fine, or both; and • For anyone else (ie, an organisation that is a PCBU): $3 million fine.

14. Fines will depend on culpability, but will be much higher than previously. There are other less serious offences under the HSWA that nevertheless attract hefty fines. Penalties frequently also involve reparation payments to victims.

15. When things do go wrong, a PCBU must notify WorkSafe as soon as possible after a notifiable event. Serious events, such as a serious illness, injury, incident or death, will need to be notified. Specific examples are detailed on the WorkSafe website. ■

SMART BUSINESS

Awkward conversations AS YOUR BUSINESS grows, you hire tradesmen and office staff. It’s an exciting time, full of possibilities. However, after a few months, the niggles set in.

Someone turns up late. Or it’s a bad attitude. Perhaps a few mistakes, and your team stop following the systems and the processes you’ve put in place.

Now, what do you do? Most people do nothing! It’s just a minor blip and you sweep it under the carpet.

But then it happens again and frustration levels reach boiling point.

Perhaps you say nothing, because you’re scared people might leave or may not like you. The rest of the team notices, they get frustrated and you find the whole culture of your operation suffers.

Eventually you get to the point where you’re ready to explode and you’re not able to be constructive. What you want is a process for having those hard conversations so you can have the confidence to take control of your business and team.

Step one is a clearly written code of conduct, which outlines the expected behaviours.

If and when the code is broken there’s a 10-step process for having those difficult performance conversations.

1. Call it This seems straightforward, but it’s usually the most challenging. If you can call the behaviour early and consistently, this will usually be enough.

2. Pick the right time It’s best to call the behaviour when it’s fresh in people’s minds. However, best not in front of clients or the team.

Humiliating someone isn’t going to get you anywhere, plus it’s unprofessional.

3. Acknowledge your feelings If you’re uncomfortable, acknowledge it! Say something like, “I don’t feel comfortable talking about this, but I’ve

50

December 2017/January 2018

been disappointed that you’ve shown up to work late the past few days.”

4. Ask permission Choose a time to call it that best suits both parties, preferably the next available time.

5. Correct the behaviour, not the person Don’t pick something personal and make them feel bad about themselves. Saying something like, “It looks like filling out your timesheets is becoming a problem.

We all agreed to this with the rules of the game, and it seems like you’re having a tough time?” What you’re doing is letting the code of conduct legislate the behaviour, as an impartial policeman.

6. State specifically what didn’t work It would be easy to turn it into a grump session about every issue, but that’s not going to help. Stick to the specific issue and deal with that. If you deal with issues early, you won’t have more than one to deal with.

How to address those niggles with team members?

Tony Fraser-Jones has some advice.

7. Clarify the benefits Clarify the benefits for correcting the behaviour, not just for the team but for the person involved.

8. Listen Let them answer without any rebuttal, and get some feedback from their perspective.

9. Acknowledge the desired behaviour When the team member exhibits the behaviour you want, acknowledge it and give them positive reinforcement.

10. Call yourself!

Leading from the front will have the biggest influence on encouraging the behaviours you want. If you break the code of conduct, put your hand up and say, “Hey guys I didn’t come up to standard; I’ll do better next time.” ■ If you want more information around having difficult conversations with staff, go to profitabletradie.com/code-of-conductenforcer for a free report titled ‘10 points to enforce your code of conduct’.

Insolvency: enemy #1

Don’t rely on a director’s personal guarantee to ensure you get paid, advises George Owen.

Q: What is insolvency?

A: In simple terms, it’s a company with more liabilities than assets.

There are many reasons why insolvency happens, but the one we will talk about here is because someone did not pay their account to the company.

The accounts receivable, or sundry debtors, are a company asset. When they disappear—or some disappear—it can have a big effect on the company’s ability to trade.

There is every chance you rely on accounts receivable to pay your bills. When you don’t get paid, because your client didn’t get paid, you can find yourself in trouble too—or with a cashflow problem at the very least. It can happen very quickly.

Q: What happens if a creditor wants to be paid and because of my cashflow crisis I’m not in a position to pay?

A: The creditor can legally serve a Statutory Demand under

section 289 of the Companies Act, asking for payment in full within 15 days. If you are unable to pay, or cannot come to some arrangement with the creditor, he has the legal right to apply to the High Court. If he can prove you are insolvent, winding up procedure might follow.

Q: How can he or she do that?

A: The Companies Act states that companies must be solvent to trade.

Q: If they prove I am insolvent what does that mean for me?

A: It most likely means the end of the road for the company and a huge loss for you. Business owners use different ways to try and protect themselves from this. The one we look at here is a personal guarantee from the company’s director.

Q: Does holding a personal guarantee ensure I will be paid?

A: Not necessarily. A director’s personal guarantee is a piece

of paper he has given you to say that, if his company is unable to pay its debts, he will pay them personally. There are many reasons why this may not happen—and it may not be quick or cheap if it does. The first is the validity of the guarantee. Not all hold up in Court if challenged.

So, it depends how much money the director has and how many guarantees he has signed.

Often, if a business person is passionate about keeping his business afloat, he will sell everything he owns to inject money into the company, so he will have no personal assets to satisfy the guarantee if the company fails. You will be out of luck.

Sometimes a business person does not feel morally or socially responsible for the debts of his company, so he will ensure he has no assets in his name when the company fails. You will be out of luck again.

Don’t assume a personal guarantee will ensure you get paid, and definitely don’t sign any personal guarantees on behalf of your company. Put a line through this clause on any form you may be asked to sign. ■ Next up, we look at what happens if the business owner has lots of money but not quite enough to pay all his guarantees—plus your potential liability if you have signed personal guarantees.

About the author: George Owen is Managing Director of Debtorinfo NZ Ltd, a Master Plumbers Business Partner.

If you have a question, call George on 0800 734 335.

Q: Do I get paid if my personal guarantee ticks all the boxes?

The guarantor cannot get out of the obligation to pay you. Either he pays, comes to an arrangement with you or goes bankrupt.

Host with the most Employers have certain responsibilities when hosting client or staff socials.

WITH THE SILLY season upon us, it’s a good time to think about those works parties that are being organised for your employees, contractors and clients, and the responsibilities of being a good host.

Social events can be a great way for employees to celebrate a job well done or to get to know their colleagues a little better away from the daily grind. However, they can easily go wrong—particularly when alcohol is involved. If people over indulge, safety and behaviours tend to go out the window, so it’s important that, as a responsible host, you reduce the risk to your employees to ensure everyone enjoys themselves and stays safe.

Set the scene—when organising the work event, let your people know what’s expected of them and the behaviours that will not be tolerated. Highlight that drunken behaviour is not acceptable. You want everyone to have a great time and enjoy the moment, and not have it remembered by drunken acts.

At such events, employees are there as representatives of your business. You want the public to see them in a good light, not intoxicated.

LOOKING FOR GREAT STAFF? Why not train your own?

By getting an apprentice into your business, you’ll have the extra pair of hands you need and staff who are ready to learn.

Take on an apprentice.

Contact us today on 0508 SKILLS (754 557) www.skills.org.nz

As a responsible host, ensure that you serve plenty of food and non-alcoholic drinks and that arrangements have been made for people getting home at the end of the night. Take care of your younger people, too. Keep an eye on them and remember they need to be 18 years or have the written consent of the parent or guardian to be allowed to drink.

Think about having your drinks served to your team rather than it being self-service, and limit the tab or have a maximum number of drinks per person by giving them a set number of tickets to swap for a drink.

Summer is here, so let’s enjoy it and stay safe. ■ About the author: Lisa Duston is HR Manager at Master Plumbers. Lisa offers HR advice to Master Plumbers’ members at competitive rates (first 30 minutes free).

Payroll changes Get your business in order for payroll changes coming in April, says Craig Hudson.

BY 1 APRIL 2018, small to medium businesses (SMEs) will experience some changes to the way they pay staff. Inland Revenue is undergoing an overhaul, bringing all of its systems and processes into the digital age. This will mean easier tax reporting and compliance for your business, and there will be changes in payroll administrators’ processes.

You may have been frustrated with PAYE in the past, trying to account for the complex variables involved in payroll.

Not only does a business’s payroll have to be accurate and flexible, but it also has to account for seasonal work and annual leave, variable rates, contractors and more.

Businesses are increasingly using cloudbased software and accounting programmes to enable information to flow smoothly between the business, the accounting software, the banks and the employee.

Inland Revenue is introducing an online system that will integrate with cloud-based payroll systems, which will make online reporting and filing part of the seamless process, allowing small businesses to reconcile in real-time.

54

December 2017/January 2018

Now is a good time to plan for how these changes will impact your business.

Firstly make sure you finish all your pay runs for the financial year. Ensure things are organised, so that when the 2018 changes roll around you won’t be left mucking around with old accounts that need reconciling.

Payroll subsidy being removed

The most critical change likely to impact your business is IRD’s removal of the payroll subsidy. Currently, the business cost of a PAYE intermediary is partly or fully subsidised for small businesses.

The subsidy is a relic of the first years of online tax filing, where PAYE information was confirmed using a listed payroll intermediary.

The reason for removing the subsidy is to establish that there is no longer a case to subsidise one type of payroll service over others. If your business has been receiving this subsidy, it would pay to do your research and plan for your next financial year so you’re not caught short.

There are many online tools you can leverage to get the most out of your accounting software. The most effective apps and online services integrate with your existing software—for example, cloud-based options like Xero.

This integration allows for a seamless flow of information between programmes

and processes. When online accounting programmes ‘talk’ to each other, SMEs get the most out of information collation.

Whether or not you choose to adopt a cloud-based software programme, make sure you get your ducks in a row for the coming financial year to ensure there are no PAYE road bumps. ■ To find out more about payroll in Xero, go to www.xero.com/nz/payroll About the author: Craig Hudson is Xero’s Country Manager for New Zealand.

Craig has been with Xero for several years, having returned to NZ from the UK, where he led Xero’s entrance into Europe, the Middle East and South Africa markets. In his current role, Craig is a key member of the global sales leadership team, responsible for driving relationships with government, financial institutions, enterprise, and promoting the small business economy.

Business security As we approach the holiday period, things get busier… and so do criminals. BNZ offers some tips on keeping it safe.

AT THIS TIME of year, increases in physical and online sales present an opportunity for criminals to entice us to provide personal and financial information.

1. Verify any changes in supplier details Invoice fraud has proved to be a significant threat to businesses throughout 2017 and is expected to rise during the holiday period. Criminals compromise email accounts, look for invoices and change account numbers to steal payments. Verify any account number changes with your suppliers, using a known phone number or process.

Avoid using phone numbers listed in emails that are sent requesting change, as they may be false.

2. Only open links and attachments on emails from senders you know or are expecting Phishing attempts and malware attacks tend to increase as the holidays approach. Watch out for emails infected with malicious software such as ransomware, which is designed to lock the files on your computers and only allow you to regain access after you have paid a ransom. Phishing emails are designed to make you click on a link and enter personal or financial information, such as credit card data. Report them to the organisation they are imitating and then delete these emails.

3. Consider what you share on social media Keep business and personal posts separate where possible. Check the privacy settings on your pages so that you’re only sharing information you allow, with people you know and trust. While you might want to share the exciting news that you’re off on holiday, you’re also publishing that your house may be empty while you are away.

4. Be aware when using public wi-fi ​ s tempting as it may be to use free wi-fi, A it potentially opens the door for others to see what you’re doing online. Avoid using banking services, password stores and online shopping when you’re on unsecure networks.

5. Increased storefront traffic and business hours If you have a physical front to your business, ensure that any festive decorations aren’t blocking the cameras, and make sure that your security system is in working order. If you’re taking a break over the holidays, don’t leave deliveries in unsecured locations. Have someone available to collect the items and sign for them, or ensure you cancel these while you are closed.

6. Preventing equipment theft Your vehicle and equipment can be an easy target for thieves, so take extra care over the holiday period to keep them safe and secure. We recommend using ABUS Close Shackle Padlocks to lock away your tools. Make sure equipment is not left unattended in your

watch out for emails infected with malicious software vehicle. If possible, park your vehicle off the road in a secure premises if you are not using it during the holidays. It is also a good idea to check that your alarms are functioning correctly and activate them when you are away. Finally, make sure you’ve got business specific insurance for your business vehicle and equipment so, if something does happen, you are covered.

7. Trust your instincts If you sense that something online or in an email doesn’t look or feel quite right, just pick up the phone and check.

Verifying information may take an extra couple of minutes, but it can potentially end up saving you a whole lot more. ■ Check out more security information at www.bnz.co.nz/support/security and take a look at cert.govt.nz for information on common security threats.

Got your NZBN?

SMART BUSINESS

The NZBN is transforming the way Kiwis do business. Are you ready?

THE NEW ZEALAND Business Number (NZBN) has been designed to save you time and effort when doing business. Over time, the NZBN will create a transactional environment with greater certainty of identity, more reliable information and less duplication.

How does it work?

The NZBN is a unique number used to identify a business. All businesses in New Zealand can have an NZBN, whether you’re a big corporate, a self-employed gasfitter or a small local plumbing firm.

Your NZBN is linked to the key business information you most often share with other businesses and government agencies—like your trading name, phone number and email address. Working in the plumbing industry means dealing with a large variety of customers and suppliers. By holding your business information securely in one place, you’ll save time and money because you won’t have to repeat the same basic details over and over again.

Because you own the information that’s held on the NZBN Register about your business, it’s quick and easy to keep this up to date.

Through the NZBN Register, your customers, suppliers and government agencies can instantly see that your business is real and tangible—giving them peace of mind in dealing with you. In turn, you can see the key information of businesses you work with, making it faster and easier to connect and transact with them.

What’s the benefit?

By streamlining business processes and making it faster to share information, the NZBN will offer you a range of benefits over time. Some initial benefits include: • •

Financial transactions will be smoother, as new ways to invoice customers, pay bills and apply for credit will be enabled Procurement will be more efficient and transactions such as onboarding new suppliers and customers will be faster and simpler

•

•

The NZBN Register will offer you more certainty about the businesses you work with—reducing risk and resulting in better decision making Businesses will be able to see supply chains, build trusted networks, improve customer service, and a whole lot more.

The future of business

More and more organisations are building the NZBN into their systems and processes right now, in areas like finance, procurement, customer relationship management, tenders, reporting and more.

These businesses may be your customers or suppliers now or in the future, and they’ll begin asking for your NZBN as part of doing business with you.

No matter what your business size, you can get and use an NZBN. Visit nzbn.govt.nz now to get yours. ■ Want to learn more? Visit nzbn.govt.nz or call 0508 696 926.

Be tax ready

When you take holidays, your tax obligations don’t. Chris Cunniffe outlines steps to ensure you’re ready for January’s payments.

HAVING TWO IMPORTANT Inland Revenue payments—provisional tax and GST—due on 15 January is never going to win most people’s favour.

After all, this is a time when business activity slows down and cashflow can become an issue as many of us take time off work to enjoy the delights of a Kiwi summer. Even the tax specialists (accountants) are quick to trade the office for the beach, BBQ and good weather.

However, having to pay the IR in January is a reality that many plumbers face. And it’s important to face it because the taxman charges usurious interest (currently 8.22%) and late payment penalties to taxpayers who do not pay on time.

So, as the sun sets on the working year, what can you do in the lead-up to Christmas to make sure you are taxready in January?

check who owes you money and see if they can pay early

58

December 2017/January 2018

A few business basics spring to mind.

Many of you are probably already doing these (apologies if it seems I’m teaching you how to suck eggs), but the small things can make a big difference.

Start by doing a financial review. Make sure you have accurate information to hand and that your books are up to date.

This will give you an indication of how your cashflow is placed.

Next, work out what you are going to need to cover expenses during the period you are off work until you start earning again. The beauty of doing a quick budget is it allows you to identify any problems you may encounter.

In terms of optimising your cashflow, make it a priority to complete jobs that can be finished quickly so you can bill clients and have money in your bank account before you clock off for the year.

Be sure to check who owes you money and see if they can pay early. Incentivise early payment by offering a discount. For outstanding invoices, be persistent and chase, chase, chase.

Conversely, if you owe creditors money, see if you can come to an arrangement to settle what you owe later.

Last, but not least, you can use an IRapproved tax pooling intermediary either

having to pay the IR in January is a reality that many plumbers face to defer payment of your 15 January provisional tax to a date in the future or to pay what you owe in instalments.

When you pay through an intermediary, you incur an interest cost that is lower than what IR charges for unpaid tax, but you get to keep cash in your business at a time when you need it most or for things that are important.

As always, do not forget to speak with your accountant. They can recommend options that help with your 15 January tax obligations. ■

From the IR: Beware cashies IN A HARD-hitting campaign from Inland Revenue, tradespeople are being reminded that every undeclared cash job leaves a trail.

The message started appearing around Auckland, Wellington and Christchurch in mid-October as part of a long-running programme to address tax crime in the building and construction sector.

Investigation work into the hidden economy uncovered $159 million worth of unpaid tax in the past year.

Inland Revenue Marketing and Communications Group Manager Andrew Stott says research shows that, although most are doing the right thing, a large proportion of undeclared cash jobs are being paid for services like building, plumbing, painting and electrical work.

“There’s a misconception out there that this work flies under Inland Revenue’s radar but undeclared income leaves a trail, which can be easily uncovered when looking for irregularities in a tradie’s books.

“You place yourself in a difficult position when you accept these jobs, so the best advice is to record everything, declare every dollar and make sure you’re charging GST if required.

“If you have been doing undeclared cash jobs, we can help you get back on track.”

A recent Inland Revenue survey found a quarter of respondents were still prepared to pay their tradesperson with cash compared to 35 percent when the question was first asked six years ago.

“It’s great that fewer people are paying cash jobs,” says Andrew Stott. “More people are aware that not declaring them is against the law. They’re grossly unfair on the tradies who play by the rules, and they take away funding earmarked for improved public services.

“We’re trying to make people in the construction industry aware that there’s a risk associated with not declaring a cash job. Hopefully this makes them think hard about whether that risk is worth it.” ■ Inland Revenue can help tradespeople do the right thing at www.ird.govt.nz/getitright. The web page includes a video of some Kiwi builders talking about why declaring all their income is important for their business and reputation.

Planning for retirement?

THREE OUT OF four small to medium businesses in New Zealand plan to fund their retirement by selling their business, yet 30 percent say the business wouldn’t survive without them— and 47 percent have no exit plan in place.

These findings are from research released in November by Xero. “The lack of planning and forward thinking by SME owners about the succession of their business is concerning, as many Kiwis will be impacted when these business owners decide to sell up or exit the company,” says the company’s NZ Country Manager Craig Hudson.

“The fact a third of owners haven’t even spoken to anyone regarding what happens to their business once they exit means they haven’t thought about who their potential buyers are, how much the business is worth and whether the business would survive without them.

“Any business owner who has put in the time, money, blood, sweat and tears to build their company would want to keep it thriving, and any owner looking to retire needs to find someone competent to take over,” he says. “The best way to make sure of that is to develop a succession plan.”

Xero’s five tips are to get an advisor on board, get your books

Every undeclared cash job leaves a trail—is it worth it?

A recent survey shows many SMEs are ill prepared for retirement.

in order, decide whether you’re going to remain involved in the business in some capacity or exit completely, and give yourself time to come to terms with the changes ahead.

Thanks go to…

Worldskills NZ would like to thank 2015 International competitor Adam De Pass, who took annual leave over a long weekend to travel up to Hamilton three weeks prior to the Abu Dhabi event. His expertise in helping Hunter with his final preparation was invaluable.

I couldn’t have managed the weekend without the help of the Worldskills NZ Deputy Manager Paul Dempster (Open Polytech Tutor), who also took annual leave to be there.

A very big thank you goes out to our sponsors The Skills Organisation, Mico Te Rapa, Plumbing World, Placemakers, SPK, Felton, Marley, Dux, Kembla, Caroma, Rheem, Masterlink, ATT, Edward Gibbon, Plastic Systems, Hydroflow and RMC. A special thanks goes to Wintec for making their facilities available, storage of materials and weekend training.

Without all your support Hunter could not have achieved the result that he did. This says a lot for our industry in New Zealand—with everyone’s input we are right up there, with the best in the world.

The search begins again for a young plumber to represent New Zealand at the next Worldskills competition, being held in Kazan in Russia. If you will be under the age of 23 in November 2019, you are eligible to attend.

NEXT GENERATION

10 of the best

Plumbing World reports back on its first-ever Young Plumber of Year event.

THE INAUGURAL YOUNG Plumber of the Year final in Hamilton was a massive success. Nearly 200 people came along to support the 10 finalists, who all did an exceptional job in representing themselves and our industry. All 10 spent the day before the competition in Auckland and were taken to a number of factory visits from sponsoring suppliers, which the guys found extremely educational and fun.

On game day, the finalists were put to the test with a demanding 30-minute questionnaire/exam, followed by an even more demanding three-hour practical test. Contestants were faced with a freestanding frame, product, tools and a basic plan to follow.

This was a basic bathroom install with behind-the-wall (piping a Rheem cylinder, Nefa valve train, simple Dux hot/cold water system with Marley pipe for a vented sanitary line and waste) and front-of-wall product (involving fixing a Felton Shower mixer/ slide shower, Toto basin, Methven mixer, Caroma pan and inwall cistern). All this within the allotted three-hour timeframe!

They were cheered on by everyone, including All Black Captain Kieran Read, and Young Plumbers Club ambassadors Logan Dodds and Jesse James.

The winner on the night this year, taking out the top prize, was Julian Parker from Rotorua, who works for The Lewis Plumbing Company. Rob Kidd, Plumbing World GM notes: “The camaraderie being developed through the Young Plumbers Club and Young Plumber of the Year is absolutely fantastic, with many friendships solidified and, as a result, lots of industry contacts made for our contestants.”

“It was also great for the event to raise the overall industry's profile and receive lots of media coverage across 7 Sharp on TV One, The New Zealand Herald, Stuff and the Rotorua Daily Post online,” says Rob. “Many thanks to all our sponsors, including Master Plumbers and Masterlink—your support is greatly appreciated.”

Plumbing World’s Young Plumbers Club is all about helping to attract and retain people in our industry, and amongst the prize pool, Julian won a trip for two to next year’s ‘Plumbing World Fun times in Fiji’ convention. 2018 is shaping up to be an even bigger competition, so keep a look out in the New Year. ■

NEXT GENERATION

Masterlink round-up

It’s been a year of intense activity for Masterlink, with several positive initiatives introduced— including a new look.

Poaching qualified staff from other firms is not going to protect our industry into the future, said Master Plumbers and Masterlink CEO Greg Wallace at this year’s half yearly meeting.

Training apprentices, however, will.

Only 19 percent of nationwide plumbing firms currently train apprentices (for Master Plumbers member businesses that figure is a healthier 36 percent).

In a bid to increase these stats, Masterlink and Master Plumbers have been lobbying for financial assistance for employers who do take on apprentices. In its 100 Day Plan, the government is promising support for employers to train 4,000 apprentices and we wait with interest to see how this will be provided.

In other advocacy work, Master Plumbers and Masterlink have raised concerns with the Tertiary Education Commission and The Skills Organisation about the consistency of PGD training delivery across New Zealand’s training providers. As a result, Skills is to conduct an independent review.

With new apprentice qualifications launching in 2018, we have provided feedback and support to Master Plumbers regarding the Level 3 and Level 4 qualifications. Master Plumbers has worked closely with Skills and the Plumbers, Gasfitters and Drainlayers Board to help ensure the qualifications meet industry needs in the 21st century.

New appointments This August, Tania Forsyth joined the Regional Manager team of four to support Masterlink hosts and mentor their apprentices in the Northland and Auckland region. Watch this space for news of a second Auckland Regional Manager to handle the workload in what is the busiest building and construction market in New Zealand.

In November, Lower North Island Regional Manager Bob McCoy was appointed to the role of Masterlink National Business Manager, working closely with all Regional Managers to develop and grow the scheme. Bob will continue in his existing role, so it’s business as usual for hosts and apprentices in the region.

Due to the volume of candidates applying to Masterlink for apprenticeships, Masterlink HR Advisor Lisa Duston now has part-time support to help handle our robust recruitment process. This includes phone, face-to-face, medical, drug and attribute testing to ensure only the highest quality applicants make the grade.

Apprentice stars It’s hard to know where to start with our apprentice highlights during the year. In April, we celebrated Masterlink apprentices 66

James Douglas Medallion overall winner Kris Rangitaawa also did his apprenticeship through Masterlink. Kris is now a registered plumber and gasfitter at Plumbing & Gas Works in Hamilton, who say he is an asset to the firm for his professionalism and high-quality work. The two finalists were also Masterlink apprentices: Colby Baker in Drainlaying and Andrew Ranger in Gasfitting.

Masterlink was a Gold Sponsor of Plumbing World’s inaugural nationwide Young Plumber of the Year, and several of our apprentices took part in the competition, including Ben Stanley in Hastings, Jarrod MacLean and Brendan Baker in Tauranga, Dave Hodgson in Rotorua, Daniel Warren in Oamaru and Lauren Phillips in Invercargill.

Lauren and Daniel made it to their regionals, with Daniel, who works with host Peter Ryder at Hi Flo Plumbing, going on to the national finals (see p64.) What an achievement!

It has been great to see Masterlink apprentices Gavin Wilding, Esmey Parata and Lauren Phillips featuring in regional, trades and careers media during the year. You may also have seen Esmey on the cover of the last edition of NZ Plumber.

Promoting our trades With plumbing business owners in many parts of NZ in desperate need of extra hands, Masterlink has been hard at work promoting and placing apprentices.

The team were out and about promoting careers in plumbing, gasfitting and drainlaying to school leavers. In May and June, we attended the NZ Careers Expo—the country’s leading careers event—held in Christchurch, Auckland, Hamilton and Wellington, with prizes for students who could assemble a double trap in double quick time.

NEXT GENERATION

In November, we had a stand at the CATE Conference in Invercargill to help get us in front of careers advisors and youth educators. The theme of the event was changing perceptions about trades careers—something we are passionate about.

Masterlink and Master Plumbers also shared a Above: Regional Managers Dave McGall and Tania Forsyth at one of the Got a stand at this year’s CPD Trade Speedmeets. trade shows. And this November, we attended four Speedmeet events, hosted by Got a Trade in conjunction with Skills. It was a great opportunity to meet students from local colleges in Upper Hutt, Christchurch and Auckland, who are interested in a plumbing career.

Health and safety The Masterlink apprentice app makes it easy for our apprentices to report any accidents, incidents and near misses. During the year, a Hazard Report Form was added to the app, enabling apprentices to report and photograph potential workplace hazards. Safety Data Sheets on the app will also our apprentices Above: Masterlink H&S rep Josh Kenyon. comply with the new Hazardous Substances Regulations.

In the spirit of the new Health and Safety Act, we are encouraging apprentice engagement with health and safety in the workplace. We have appointed an apprentice member to Masterlink’s Health & Safety Rep team. Welcome and thank you to willing volunteer Josh Kenyon. Masterlink apprentices can use a new Social Wall feature on the app to raise any health and safety issues with Josh.

Masterlink once again received tertiary level ACC accreditation for our Workplace Safety Management Practices during the year. “It’s great recognition of the focus we place on ensuring a safe and healthy workplace,” says Operations Manager Kate Jenkins.

All systems go Paper timesheets are now a thing of the past at Masterlink. A user-friendly online apprentice timesheet process was rolled out during the year, with full training provided for all host business.

The new online payroll system has had positive feedback from hosts, with many wanting to use it within their own businesses.

We have also introduced the BWARE system to collate reporting of any accidents, incidents, near misses and hazards by our apprentices.

Sign-ups and certificates We’d like to congratulate all our National Certificate recipients in 2017: Kelly Adam, Mason Anstis, Michael Armitage, Brendan Baker, Jarrod Bryan, Liam Driver, Gregory Ede, Jared Frew, Harry Gedye High, Harrison GreyBird, Ian Hill, Michael Judd, Above: Matt Park receiving Alex Mitchell, Matt Park, Glen his National Certifcate from Robertson, Gus Wilmot and Isaac Regional Manager Tania Forsyth.

NEXT GENERATION

There is currently some cautiousness in the market. Some companies are holding off signing up apprentices until the New Year, as they wait to see if there will be government funding for employers. By mid-November, Masterlink had 59 sign ups

nationwide—slightly under the 2016 figure of 61, but an increase on all previous years. Sign ups in Auckland are lower than last year due to staffing changes in the region. However, all other regions are ahead of last year’s sign-up numbers.

Clamp that

See into walls

Cofix Black—the clamp with the staunch grip.

Map pipes, wires and studs with this non-destructive service locator.

Get your clamp on with the newly-introduced Cofix Black range of Munzen rings, designed to eliminate the most commonly encountered installation problems with metal clamps—dropped screws and time consuming installation.

The Cofix Black range steps up with full seismic test data to comply with NZ stringent earthquake code. The result? Just like it says on the tin: effortless install and staunch grip.

The clamps are specifically sized to fit each pipe type and size perfectly, ready to handle any job where piping is installed. The rubber insert not only delivers a grip that doesn’t let go, it also eliminates rattling.

The Cofix Black range is available now from leading merchants.

It can be hard to locate services hidden behind the wall without hitting live services, missing studs, or damaging floors and walls.

Walabot is a unique device that can x-ray a wall up to 100mm in concrete, and detect pipes, studs and wires from the start to finish point—without the need for numerous scans.

Designed to complement android phones (iPhone Walabot device under development), Walabot is compliant for use in Australia and New Zealand, and offers tradespeople a very cost effective option for a non-destructive location device. It is powered by a highly advanced 3D sensor, based on cutting-edge medical technology.

Walabot is distributed in New Zealand by X-Ray Imaging Ltd. The company also distributes pipe and drain inspection cameras.

Asbestos locator New software for asbestos management.

New regulations that require all NZ workplaces to identify asbestos and to have an asbestos management plan by next April has seen the creation of a unique software management programme: the Building Materials Information System (BMIS).

BMIS helps identify and manage asbestos in a building likely to be disturbed by routine maintenance.

Through scanning of QR codes or website access, workplaces that use BMIS can provide workers access to plans and up-todate information about the locations of asbestos in a building.

BMIS provides online training for contractors to provide information on how to read management plans, and what to do if asbestos is discovered, as well as a basic understanding of asbestos.

Offcuts

This edition’s media snippets of the plumbing kind.

That’s my swamp

Florida’s Cape Coral is a disaster waiting to happen, according to an article in The New Zealand Herald in October. Built in the 1960s from ‘a soggy floodplain’ of drained mangrove swamps just 1.5m above sea level, it is now one of America’s fastest growing developments. The town was designed without water or sewer pipes, says the article. Developers dug 643km of canals (more than Venice) to act as both selling point and stormwater plumbing. Water from a salty pool 250m underground must be treated to make it fit for consumption. Cape Coral also narrowly escaped Hurricane Irma in September. Residents were ordered to evacuate, but the Red Cross declared the town too vulnerable to bother opening shelters, as it is so low to the sea, according to the article.

Behind the eight ball?

Construction firms across NZ are struggling with the uptake of even basic digital technology, reported Stuff in October. A Spark survey of 270 construction firms showed only 23% felt they had the digital skills to perform their jobs correctly and understood what could be done online. According to the survey, small to medium sized construction firms (fewer than 100 employees) were also less likely to have an online presence than any other sector.

Apparently, time to learn skills was a major factor.

Digital skills could make a big difference to efficiency, said the article—and having a company website was ‘the tip of the iceberg’. Modelling, prefabrication and robotics were all things that would eventually make a major difference to the construction sector’s low productivity rate, it noted.

Game of drones

A Spanish firm is pioneering a drone project to speed up and improve the inspection of Barcelona’s 1,500km sewerage system, reports WaterWorld magazine. The aerial robot (somewhat unfortunately known as ARSI) is equipped with multiple sensors to monitor water and air quality, including a 3D camera to calculate its position and a 2D laser to detect walls and calculate flight paths, says the magazine.

If it’s good enough for the Queen…

Some of the 108 shops around the world where the Queen gets her groceries were revealed in a recent article in UK newspaper The Telegraph. To get a spot on the Royal Warrant register and the right to bear a coat of arms on its packaging, all must have supplied the Royal Household for more than five years, according to the article. But it’s not just food and drink that gets on the list of the best of the best. “The register stretches to more than 800 names, with other firms providing anything from tailoring and plumbing to cleaning and cars.” Take a bow, A Hester Ltd, says the article, for being the Royals’ preferred septic tank services company.

Not a bar of it

This anonymous entry is of a dodgy job done at a Hamilton bar.

Long-distance runner

“Another dodgy homemade plumbing and gasfitting installation,” says Chris Downey of Tuffnell Plumbing in Nelson. “Of course this has now been put right.”

Old potboiler

“Photos of a discovery in an old South Dunedin house,” says Alan Sorrell of Barry Dell Plumbing.

“Valve on top of pipework to allow you to fill up pots with hot water; a rubber radiator hose for seismic and thermal movement; and the radiator cap on the bottom to allow for easy draining and as a temperature/pressure relief.

“This way when it boils it will spray boiling water down and at a lower level, thus making it somewhat safer—because if it was at the top it could spray up and all over the place, thus causing a serious injury (LOL). You may also notice the conveniently installed isolation valves to make further maintenance a breeze (LOL).”

A bob each way

“Found this on a low pressure cylinder. I guess they weren’t sure if it was a mains pressure cylinder or a low pressure so they’d fitted both valves. That’s diy farmers for ya,” says Tim Charlton at Tauranga Plumbing.
