By the time you read this, plumbers, gasfitters and drainlayers from around New Zealand will be gathering in Brisbane for the 2025 New Zealand Plumbing Conference. Everyone will be looking forward to connecting with industry networks and browsing the trade exhibition to see what new technologies have arrived in the market.
At a previous conference, entrepreneur Sir Ian Taylor noted just how much innovation was on show in our industry – and he’s right. Ours is a community of creative thinkers and practical doers. Max Semmons-Russell, who features on our cover, is a prime example. With his first-hand experience of the challenges in running a plumbing business, Max has come up with a software solution that he hopes will make tradespeople’s lives easier. Turn to page 24 to find out more.
We also take a look around New Zealand’s first 3D-printed showhome (page 46) to discover what this technology means for plumbers when installing pipework, and visit the brand-new Nero Tapware showroom in Auckland (page 40)
to learn about their focus on supporting the plumbing industry.
Nero’s tapware products are made with the lowest possible lead content. It’s a move all New Zealand’s tapware manufacturers and suppliers are making ahead of the new lead-free requirements coming into effect on 1 May 2026. Learn what this means for the plumbing industry in our feature article on page 14. Finally, our technical theme this edition takes a look at the increasing popularity of innovative heat pump water heating technologies in New Zealand.

ON THE COVER
Max Semmons-Russell is an ideas man – his brain moving a mile a minute with innovations that he hopes will make life easier for tradies. When not running his Auckland-based KPA Plumbing business, Max is flat out on his tech solution, Green Light Escrow, designed to ensure tradespeople get paid for the work they do. NZ Plumber chatted with Max about why he’s on a mission to help fellow small businesses and how he manages to combine this with family life and enjoying time with their two young children. Read Max’s story on page 24.

CEO’S REPORT
I’m really looking foward to the Master Plumbers conference in Brisbane. We have more than 300 attendees and it’s our first offshore conference in six years. Holding an offshore conference is always a challenge and our team works incredibly hard to provide a good experience and content.
As we move closer to 1 May 2026, when the lead-free plumbing product regime is implemented, there seem to be questions around its necessity among some suppliers and merchants. The reality is, the 2018 Macquarie University Report by Professor Mark Taylor was very clear that no level of lead is safe in drinking water.
It is the responsibility of plumbers in New Zealand to provide safe drinking water for New Zealand consumers and I don’t agree with arguments that we should be influenced by cost, or other arguments that are not evidence based.
I do agree that the downturn in the construction market has caused some stock movement concerns, but this leadfree change was signalled more than three years ago. For anyone to say it comes as a surprise is hard to believe.
My concern is how the Government will police the regime. It is completely unfair and unreasonable that some product suppliers have invested heavily in the technology to comply when there is no guarantee those who haven’t will be stopped from entering the market.
Master Plumbers will continue to advocate for compulsory labelling on products or
packaging, as we think this is the only way that both consumers and installers can easily identify lead-free products.
We must also remember that Australia has a much stronger compliance mechanism with the mandatory WaterMark system, which now includes
“From
1 May 2026, you will only be able to install products that you know comply with the new lead-free regime – and that will mean identifying products as lead free.”
lead-free compliance. The WaterMark regime includes independent testing and auditing. Compare this with New Zealand, where there seems to be a misconception that Building Product Information Requirements will ensure compliance.
This is short sighted and misguided by MBIE, which has no authority over offshoredomiciled suppliers. Without compulsory labelling, lead-free requirements are toothless for the likes of online resellers, such as Temu and AliExpress, which are ever expanding in number.
We all need to focus on the fact that this is a public health issue rather than
a building product issue. I would like to advise members that from 1 May 2026, you will only be able to install products that you know comply with the new lead-free regime – and that will mean identifying products as lead free.
On another matter, we are expecting consultation to open shortly on the proposed self-certification scheme for plumbers and drainlayers. At Master Plumbers, we will be making sure the proposal is practical, requires good data and record keeping, and also meets the needs of industry by improving productivity.
We will also be suggesting that any new regime aligns with a review of the gasfitting self-certification process. We feel that, at times, MBIE tend to overcomplicate things rather than look for solutions. Our consultation feedback will seek to ensure the process is robust but also practical.
Finally, with the new Level 4 PGD Industry Trained Apprenticeship programmes now underway, I want to remind members that training assessment and verification can now happen on the job and the process shouldn’t be onerous. I would encourage you to talk to your training provider about this new approach. If you need any assistance or advice, please reach out to the team at Master Plumbers.

FIRST LARGE-SCALE UPVC REPROCESSING FACILITY FOR NZ
The ability to reprocess plumbing and drainage pipe took a major step forward with the launch of the PRNZ North Island recycling plant in March.
Aliaxis NZ and WM New Zealand have brought together their expertise in waste collection and plastics manufacturing by establishing Plastics Recycling New Zealand (PRNZ). The mission for PRNZ is to close the loop on plastic waste, reducing the need for virgin materials and supporting a circular economy. None of this would have been possible without the generous support of the Ministry for the Environment’s Plastics Innovation Fund.
In March 2025, together they launched the PRNZ North Island recycling plant – operating the only large-scale uPVC reprocessing facility in New Zealand, investing in plastics recycling with a nationwide collection and processing network. This plant is in addition to the 2023 acquisition of Comspec, a specialist plastics recycling plant in Christchurch.
Aliaxis NZ manufactures many of its products from uPVC and HDPE, robust materials with a lifespan of up to 100 years in infrastructure and construction. By recycling these plastics into highquality products, they greatly reduce the demand for new plastic production and ensure valuable resources remain in circulation.
Recycling plastic waste into high-quality products supports a circular economy.

Misuse of market power: have you been affected?
New information is available from the Commerce Commission to help small and medium-sized businesses understand how they might be affected by the misuse of market power. Laws are in place to prevent powerful businesses behaving in a way that could harm healthy competition.
Examples of potentially illegal behaviour include:
Refusal to supply: Refusal to sell a ‘must have’ product or service to a rival business.
Price/margin squeeze: Pricing rivals out of the market on ‘must have’ products and services that aren’t readily available elsewhere.
Tying and bundling: Making the sale of one product or service conditional on the purchase of another.
CPD ROADSHOW BOOKINGS NOW OPEN
Bookings are now open for the Plumbers, Gasfitters & Drainlayers Board 2025 CPD Roadshows, sponsored by Reece and hosted by CONZTRUCT. The sessions will take place in 24 locations, starting in Greymouth on 13 May. This year, 16 sessions will take place at CONZTRUCT Tradeshows. The 2025 CPD programme will include upskilling on carbon counting,
Predatory pricing: Reducing prices below operating costs for a long time, or at strategic times, to force rivals to leave the market.
Exclusive dealing: Entering into contracts that contain ‘exclusivity’ clauses with customers or suppliers to prevent them doing business with competitors.
Loyalty rebates: Structuring loyalty rebates or discounts in a way that makes it harder for customers to switch to a rival business.
Find examples of each behaviour and information on how to report concerns at www.comcom.govt.nz (information for small and medium businesses)

GUIDANCE ON CHANGES TO DUTIES OF AN INDEPENDENTLY QUALIFIED PERSON (IQP)
The Ministry of Business, Innovation and Employment (MBIE) have issued new guidance about changes to the Building Act 2004 regarding ‘Duties of an independently qualified person’, under Section 108A.
This new section closes a regulatory gap by clarifying that IQPs must only issue a certificate for a specified system if the inspection, maintenance, and reporting procedures stated in the compliance schedule have been fully complied with during the previous 12 months.
It also makes it an offence to issue a certificate when a specified system has not met these requirements. A person who acts in breach of this requirement commits an offence punishable on conviction, in the case of an individual, by a fine not exceeding $50,000, or, in the case of a body corporate, by a fine not exceeding $150,000.
This change accompanied recent earthquake-prone building legislation changes. For more information, see www.building.govt.nz/about-building-performance/ all-news-and-updates/earthquake-prone-building-legislation-changes
NEW LEGISLATION PAVES WAY FOR WIDER RANGE OF BUILDING PRODUCTS
Up to 250,000 more building products are expected to be available in the New Zealand market this year under Building Act changes, announced in April.
The changes follow the Commerce Commission’s 2022 market study of residential building supplies, which highlighted a lack of competition. This has contributed to high product prices and a 40% rise in construction costs over the past six years.
More options for products like plasterboard, cladding and insulation should ensure alternatives are always available if there are product shortages, meaning projects can continue without delays like those experienced during the Covid pandemic.
A new building product specifications pathway will be introduced in July to streamline the process of citing international product standards that can be used with acceptable solutions or verification methods to establish compliance with the Building Code.
Regulations will be developed later in the year, so the Building and Construction Minister can issue a notice recognising groups of overseas product standards and certification schemes.
Councils will be required to accept building products and methods that have been certified by an overseas product certification scheme and recognised by MBIE, as long as products are used as intended.

Dr Daniel Timms invented the BiVacor total artificial heart in the early 2000s after his father Gary, a plumber, had a heart attack, reports Stuff The pair apparently built the first prototypes on their kitchen bench in Brisbane, using bits of pipe bought from Bunnings. In what’s being heralded a game changer, an Australian man in his 40s has now become the first in the world to leave hospital with the artificial heart in place, while awaiting a traditional heart transplant.
Auckland Plumbers Group love their community and have confirmed their support by agreeing to a three-year naming rights arrangement for the Auckland Plumbers Group Pavilion at Royal Oak Bowls. The fully undercover bowling pavilion is a fantastic facility, says this 2024 NZ Master Plumber of the Year member business, and has been very well received by serious and social bowlers alike.
Mike Ellis and Marley Bob from Master Plumbers member business Ellis Plumbing & Gasfitting in Lower Hutt got dressed up in blue to wish everyone a happy World Plumbing Day on 11 March. Four-year-old Marley Bob is employee of the month, says Mike. “He’s picking up the plumbing gig really quick, very good with the hemp.”
Karl Boniface was the plumbing project manager behind the Southern Charity Hospital, which officially opened its doors in March. Karl, who runs Master Plumbers member business Karl Boniface Plumbing in Invercargill, was among several other tradespeople working on the entirely voluntary project. The hospital was the dream of Blair Vining, who was given just weeks to live after a bowel cancer diagnosis at the age of 38 and wanted to ensure fairer access to cancer care for everyone. After his death in 2019, Blair’s wife Melissa continued their shared vision to fundraise and get the hospital built.
Project lead Melissa Vining hugs plumbing project manager Karl Boniface at the opening event.
Goldsworthy, aka Plumber Dan, took part in the 2025 Pork Pie Charity Run from 4-9 April – his third time taking part in the epic adventure, which sees hundreds of Minis heading on a 2,300km, 6-day journey from top to bottom of New Zealand, with a goal of raising a total of $500,000 for Kiwi kids’ charity KidsCan. Dan also auctioned off his 1980 v6 Morris Mini, another of his crazy cars to have taken part in the run, with all proceeds going to KidsCan. “The previous owner of the Mini is dead keen to get it back and he’s currently leading the bidding… we hope the auction gets to at least $20k,” said Wendy Johns, Plumber Dan finance and administration lead, in March.
The Hirepool Big Clean in Onehunga in March saw over 300 volunteers removing 880kg of rubbish to look after the local environment. The half-day event was a collaboration with Sustainable Coastlines, designed to raise awareness of the impact of plastic pollution on humans and marine animals, including the critically endangered Māui dolphin. “Seeing so many people come together to protect our coastline is truly inspiring,” said Hirepool CEO Brian Stephen. “The effort and enthusiasm of everyone involved highlights the real impact we can make when we work as a community.”

John Evans, a 70-year-old semi-retired plumber, is raising funds for children with ADHD and neurodiversity, having cycled his way from Cape Rēinga to Bluff. John thought he would do something useful while waiting for hip surgery and set off in late February on his ‘One Hip and a Prayer’ journey with son Matt – and wife Debbie following along behind in the campervan. He completed the journey on 23 March, despite a fractured shoulder from an incident with a pothole in Timaru!
John’s goal is to promote awareness of the need to get the right support for neurodivergence early on in life. It’s a cause close to his heart, with a daughter and grandchild both having this diagnosis. Funds raised will go to the Acorn Charitable Trust, which provides teachers and students with training and resources.
To donate to John’s cause, the Acorn Charitable Trust, visit www.acornneurodiversity.co.nz
Plumbuilt Plumbing were the lucky recipients of a $1,000 fuel voucher in the recent Hirepool Fuel Frenzy Giveaway. A total of $60,000 fuel vouchers were up for grabs for anyone making a hire through Hirepool during February and March. And being a member of Master Plumbers, Plumbuilt is also eligible for trade rates less 20% on Hirepool hire equipment. A win win!
Team Master Plumbers is raising funds for MATES in Construction by taking part in the MATES Long Lap throughout April. They are joining teams across New Zealand to run, ride, swim, walk or wheel towards a combined goal of 15,000km – equivalent to traversing New Zealand five times. The aim is to raise awareness for mental health and suicide prevention across the construction industry, while acknowledging the industry losing a worker to suicide every five days.
Visit mateslonglapnz.net.nz if you would like to donate to the cause by 14 May.
If you’re a plumber with product stored in your truck, van or workplace, be sure to make use of your current inventory ahead of the new lead free rules being implemented on 1 May 2026. Get the full lowdown here.

DEZINCIFICATION RESISTANCE IN PLUMBING PRODUCTS
As part of the 2022 Building Code update, Acceptable Solution G12/AS1 Water Supplies was also amended to:
clarify that copper alloy water supply system components must be dezincification resistant to reduce the risk of corrosion.
Q: What’s changing and when?
The dezincification resistant copper alloy provision in G12/AS1 will be effective from 1 May 2026. Following this date, any copper alloy water supply system components in contact with water and subject to hydrostatic pressure must be dezincification resistant.
Dezincification resistant copper alloy components are also required by some product standards applicable to compliance with Acceptable Solution G12/AS1. Until 1 May 2026, the dezincification resistance requirements of those standards must still be met.
Q: What is dezincification?
Dezincification can occur when a copper alloy (such as brass) containing more than 15% zinc comes into contact with natural or treated waters. Dezincification is a corrosion process where a copper alloy undergoes selective leaching of the zinc into the water supply, leaving only a porous copper residue. Particular types of copper alloy can be used for manufacturing plumbing products which give resistance to dezincification corrosion.
Installing dezincification resistant brass water supply system components protects both consumers and plumbers by ensuring these products are sufficiently durable, particularly where these products are installed behind the wall or in concealed locations.
Q: Will all copper alloy water supply system components have to comply?
The dezincification resistant copper alloy provision does not apply to water supply system components that are not subject to hydrostatic pressure, such as shower heads and bath spouts that are open at one end.
Q: What’s the advice on brazing brass fittings?
Brazing can affect the dezincification resistance of brass fittings. Plumbers should avoid localised ‘hot spots’ and perform brazing operations at as low a temperature as is practicable when brazing brass fittings.
Q: How can I identify compliant dezincification resistant products?
Building product information requirements – These regulations place obligations on New Zealand-based building product manufacturers, importers, retailers and distributors to state how their product complies with the relevant Building Code clause. Building product information should clearly state how an in-scope plumbing product is expected to contribute to compliance with the Building Code, including clause B2 Durability.
‘DR’ identification marking – Brass water supply system components marked with the letters ‘DR’ indicates compliance with the dezincification resistance provision.
AS 2345:2006 test report – A test report provided by a test facility with IANZ or equivalent accreditation in accordance with AS 2345, which verifies compliance with this standard.
Q: What’s changing and when?
As part of the 2022 Building Code update, G12/AS1 Water Supplies was amended to: limit the maximum allowable lead content in copper alloy plumbing products intended for use in contact with potable water for human consumption. The lead in plumbing product provision in G12/AS1 will be effective from 1 May 2026. Following this date, plumbers who install such products are responsible for ensuring they are lead free.
‘Lead free’ is defined in the updated Acceptable Solution G12/AS1 as a plumbing product or material in contact with potable water that has a weighted average lead content of no more than 0.25%.
Q: How does this affect building consent applications?
Consent granted on or before 1 May 2026 (including consented projects under construction)
Consent application made on or before 1 May 2026
Work can proceed using Acceptable Solution provisions approved by the building consent.
Application may continue to comply with the Acceptable Solution provisions in place on the date consent application was made.
Consent application made on or after 2 May 2026
Application must follow the updated provisions when using Acceptable Solutions as a means of compliance.
For plumbing work exempt from requiring a building consent under Schedule 1 of the Building Act 2004, the plumber who carries out the work is responsible for ensuring the products and methods used in carrying out the work comply with the requirements in effect at the time of installation
The letters DR on a brass component indicate that it is dezincification resistant.
valves (eg, valves for isolation, backflow prevention, alteration of pressure and temperature)
taps and mixers
water meters
pumps (for use with cold and hot water supply systems)
water heaters
residential water filtration equipment
water dispensers (eg, boiling and cooling units, drinking fountains and bottle fillers)
fire sprinkler systems connected to cold water supply systems and not isolated from fixtures and fittings intended to supply water for human consumption.
Q: What kind of products won’t have to comply?
showers and baths for bathing, including shower and bath mixers
emergency showers, eye wash and/or face wash equipment
pumps used for irrigation, fire-fighting or other non-potable water purposes
fire-fighting water services and equipment
appliances, including clothes washing machines and dishwashers
commercial boilers associated with heating, ventilation and air-conditioning systems
sanitary fixtures (eg, toilets, cistern inlet valves, bidets, urinals) non-potable water systems (such as recycled water systems)
products used exclusively for non-potable uses such as manufacturing, industrial processing, irrigation or any other uses where the water is not anticipated to be used for human consumption.
Q:
How can I identify compliant lead free products?
1. Building product information requirements – These regulations place obligations on New Zealand-based building product manufacturers, importers, retailers and distributors to state how their product complies with the relevant Building Code clause. Building product information should clearly state how an in-scope plumbing product is expected to contribute to compliance with Building Code clause G12 Water Supplies, including G12.3.2 (c).
2. International product certification scheme markings – These can indicate compliance with equivalent requirements in other countries.
Australian Lead Free WaterMark Mark of Conformity
American National Standards Institute (ANSI) accredited third-party certification body. Lead Free certification marks (nepis.epa.gov).
3. NSF/ANSI/CAN 372:2020 test report
– A test report provided by a test facility with International Accreditation New Zealand (IANZ) or equivalent accreditation in accordance with NSF/ANSI/CAN 372, which verifies that a product has the required weighted average lead content of ≤ 0.25%. This American National Standard establishes a standardised methodology for the determination and verification of product compliance to minimise lead contaminants. This standard serves as the basis to establish conformance with the G12/AS1 lead in plumbing product provision.
Additional information on the transition to lead free plumbing products is available at building.govt.nz
“As the installer, you are responsible for ensuring any product you install meets the lead free requirements.”

Clarus company, Firstgas is blending and testing a small amount of hydrogen with natural gas in a handful of Kiwi homes in Te Horo. This milestone project is a New Zealand-first and marks a turning point in clean energy innovation, helping our country take another step towards decarbonisation and a net zero carbon energy future.
James Irvine, General Manager Future Fuels at Clarus explains, “The beauty of blending hydrogen with natural gas is its seamless integration—appliances work as they always have, delivering the same comfort and performance New Zealanders rely on. The technology is proven overseas, and we’re now demonstrating its potential here.”
Hydrogen is an exciting low carbon prospect because it can be made cleanly using just water and renewable electricity. It’s also storable and transportable at large scale.
So what is happening, and where?
Hydrogen blending equipment has been installed and connected to the Firstgas distribution pipeline in Te Horo. Selected local households are taking part in the initiative, using blended gas in their home appliances. Hydrogen is incrementally mixed with natural gas, starting at 2% and increasing to a maximum of 15%, all while meeting strict safety standards. Key regulatory exemptions have been granted by WorkSafe NZ.
“Te Horo is the perfect starting point due to its pipeline compatibility and community support. Beyond this pilot, the future of hydrogen in pipelines could provide a low carbon option for homes, businesses and industry,” adds Irvine. “It’s about using our existing infrastructure to create a cleaner, sustainable energy future.”
Hydrogen blending is a proven success overseas. In Australia, it has been powering over 2000 homes since 2022. For New Zealand, this pilot is just the beginning of exploring renewable gas as a low-carbon energy source. And it shows that natural gas still has an important role while we transition to renewable energy.
New Zealand has always been a country of pioneers and Clarus continues to lead the charge in renewable energy innovation; from a vision five years ago to today’s reality. Irvine says, “This is a landmark moment for Firstgas and our partners Vector, Powerco, GasNet and Nova Energy, setting the stage for safely blending hydrogen with natural gas in the existing Firstgas pipeline network.”

Plumbing business owner Max Semmons-Russell has developed Green Light Escrow technology to help fellow tradies keep their money safe.
IDEAS IN ACTION
Having found himself owed $50,000 when a builder went belly up, Auckland plumbing business owner Max Semmons-Russell put his mind to a software solution that would ensure tradies get paid for the work they do. NZ Plumber talks to Max about his drive to innovate for the benefit of the trades.
AUTHOR: BEVERLY SELLERS

Plumber Max Semmons-Russell has a big goal – to forever change the way tradies get paid. The idea was sparked when he was left $50,000 out of pocket on a home reno after the builder his business was working for went bust.
With a mortgage to pay and a young family to feed, Max was left with no option but to work his way out of debt. He got there, but it made him wonder why tradies have to act as the bank – bringing all the labour and materials upfront to a job, but having to wait till completion to get paid.
“Imagine going to a McDonald’s drivethrough, ordering your food, and then paying for it a month later,” says Max. “Not a lot of businesses use that model. Equally, you can’t hand out your Eftpos machine to the customer every time you swing a hammer.”
Holding the money in the middle with an independent third party seemed to him to be the ideal solution. This way, the tradie knows the client can’t withhold the cash,
and the homeowner knows the tradie can’t ride off into the sunset with their deposit. As Max says: “If someone is lucky enough to buy a house, it’s probably the biggest purchase they will make, so they want to know their money is safe.”
He looked around for a service of this kind, but with no luck. So he decided to create his own... and the Green Light Escrow desktop app was born.
‘Escrow’ is an ancient word still commonly used in the US. Essentially, it’s money held in trust by an independent third party, and released on the fulfillment of conditions agreed between the two parties.
Max uses it in his own business, KPA Plumbing, and says he feels reassured knowing he will get paid for the work he does. His clients also prefer it to paying a deposit before work begins. It’s simple, he adds – once the tradie and their customer have each given the green light, the money gets released, either in one go or in milestone payments for larger projects.
One plumber who has used the Green Light Escrow app on a $7,000 job says his next will be a $30,000 project for a contractor, with milestone payments to be made in five stages – drainage, pre-slab, pipe out, fit off and installation of stormwater tanks.
“Imagine going to a McDonald’s drive-through, ordering your food, and then paying for it a month later,” says Max. “Not a lot of businesses use that model. Equally, you can’t hand out your Eftpos machine to the customer every time you swing a hammer.”
Ideas into action
Anyone who’s met Max will know he’s a mile a minute. Diagnosed with ADHD in later life, having been asked to leave school at 15, he has turned neurodiversity to his advantage. “It got me into trouble before, but it’s now taking me places,” he says.
Somehow, Max manages to combine running his team of four on the tools at KPA Plumbing with growing the Green Light Escrow software, while also making time to take his children, Ava, who’s 13 and August, seven, to their after-school sports.
He puts it down to being flexible, despite clocking up 80 to 100 hours’ work a week. He also credits the support of his partner Kayla, who raises the children, helps with the business admin and listens to all his ideas.
Turning ideas into reality takes effort, of course, and for many it’s a risk they’re not willing to take. Not so for Max, who
has always loved high adrenaline sports –skateboarding from the age of five, surfing and doing Braziliae jiu-jitsu.
Prepared to take the leap, he also gathers good people around him with the skills to bring his ideas to life. His co-founders at Green Light Escrow are legal specialist Adam Jennings and senior software developer Shai Fernandez, with a junior developer joining the team in recent months.
Adam is the one to ensure Green Light Escrow complies with anti money laundering (AML) and other laws and regulations. Shai, meanwhile, is behind the software functionality, also developing an AI chatbot service to answer any questions the tradie or homeowner may have.
Max is particularly proud of the fact that Green Light Escrow has secured a ‘liquidation clause’ to protect both the homeowner and tradie. “Whichever party
liquidates gets locked out of the deal, ensuring the opposite party gets paid,” explains Max.
With the new rules around retentions, head contractors are also looking to Green Light Escrow as a way of holding monies in trust for large-scale construction projects.
Where life leads
Max, who’s now 37, would never have imagined himself in the world of tech software. Following his early exit from school, he spent time as a labourer, getting up at 5.30am each morning ready to be driven in the van to one of the many construction sites popping up around Auckland at the time.
Joining Master Plumbers has provided him with a trusted community of professionals he can call for advice at any time.
His father, a solid plasterer, suggested a plumbing apprenticeship for his son and Max took his advice. “Unlike my dad’s work, plumbing is indoors and outdoors, so there’s always work, and you’re at different jobs most days, not stuck on one site. I was very happy to be working and earning.”
Qualified at 21, he honed his plumbing, gasfitting, drainlaying and roofing skills at various companies around Auckland, before deciding to go out on his own at 30.
“Looking back, there was a lot to learn,” he says. “I’m good at my trade but you don’t learn business skills at plumbing school. Suddenly I was fending for myself in the wild, wild west, which can be cut throat and full of opportunists.”
Joining Master Plumbers has provided him with a trusted community of professionals he can call for advice at any time, and he’s enjoyed meeting up with fellow members at Auckland branch events, such as fishing trips and the FIA Rally Championship.
A plumbing career has been good to Max, but he has learned the hard way that even the best business can stumble when a client fails to pay. He hopes his Green Light Escrow business will save others from this experience by receiving proactive support at the start of a project rather than ending up in court trying to claw back unpaid money on completion. “I just want to make life easier for tradies,” he says.

OUT & ABOUT
Fishing, golf and driving range fun have been among the recent activities around the Master Plumbers regions. Plus, celebrations for some new Association Life Members.
Out on the water
Fishing was the name of the game for 55 keen anglers from the Auckland, Bay of Plenty/Coromandel and Waikato Master Plumbers branches in February. A stunning sunrise heralded the start to the day, which saw competitors vie for the top prizes, including the branch trophy, snagged this year by the Waikato branch. Chelsea McLaren of Marley (pictured) took out the prize for the biggest catch, reeling in a 65cm snapper. The event included a fabulous fish feast and prize-giving at the local bowling club, with everyone getting to take home a fresh fish for tea. “Huge thanks to Hirepool, Marley, Aqualine and Iplex for their sponsorship of the event,” says Waikato President Mike Wilson.
At the driving range
Drinks, nibbles and some driving range fun were had by the Manawatū Master Plumbers in mid-February. The group met up at the amazing Orlando Country venue outside Palmerston North and it was great to see a few new faces on the night.
On the golf green
Taranaki members, suppliers and sponsors gathered at the Westown Golf Club in March for some competitive action on the green. The day included a BBQ lunch and drinks on the course to keep players energised, plus some post-round burgers ahead of the prize ceremony. “Thanks to our incredible sponsors, there were some exciting prizes up for grabs, including a hot water cylinder, kindly sponsored by Rinnai,” says Taranaki Master Plumbers President Daniel Brooks. “Vepo Plumbing and Verve Plumbing also won vouchers from Plumbing World and Mico, our main sponsors of the event.”
Congratulations to Blair McNab
Blair McNab has been acknowledged as an Otago Master Plumbers Branch Life Member for his more than 20 years of commitment and outstanding contribution to the branch. During this time, Blair has held several roles, including Branch Secretary and President. He has helped steer the branch through its transition from an association and remains an active member of the executive committee.
“Blair has invested much of his time and energy over many years, helping organise many events, and is generous with his industry knowledge, providing great support and mentorship to fellow members,” says current Branch President Baz Rogan. “He has attended many conferences and training forums held by the Society, where he has made long-lasting friendships and represented
the Otago Branch exceptionally well.”
Blair McNab Plumbing in Dunedin is locally renowned and respected for quality tradesmanship, and Blair has trained a number of apprentices throughout his career, some of whom have gone on to become business owners and Master Plumbers members in their own right.
“Blair’s passion for recognising and celebrating the success of others in the industry is also demonstrated by his role as a trustee for the Mac McKenzie Trust,” says Baz. “The trust gives us the opportunity to come together each year to acknowledge high-performing apprentices from across Otago, Southland and Queenstown Lakes – making this the perfect event to bestow Otago Master Plumbers Branch Life Membership upon Blair.”
Some planningsurprisemeant Blair and Debbie McNab were able to celebrate Blair’s Otago Master Plumbers Branch Life Membership award with all three of their children – Bradley, Olivia and Dan. Bradley (left) travelled from Christchurch and Olivia (second from left) from Melbourne. Dan attended with partner Nikole Robson.
Canterbury Life Membership awards
This March, Canterbury Master Plumbers held its final AGM as an association before transitioning to a branch. There was an awesome turnout, with national President Grayson Allen making the special trip to attend. He was delighted to award two Association Life Memberships at the event to Martin de Gouw of Clyne & Bennie and Barry Willcox of Willcox Plumbing.
Both Martin and Barry have held key executive positions, including Chair and/or President, making a lasting impact on the association and the wider plumbing community. This prestigious recognition celebrates their dedication and service to the industry, having worked on behalf of members for over 25 years.

ENDURO TEAM BUILDING FOR MASTERLINK APPRENTICES
Masterlink apprentices Nathan Giddens and Mason Tombleson were among the team of four from CF Reese Plumbing to take up the challenge of the 2025 Taupiri 24hr Farmbike Enduro this February.
The massive 695km endurance race is physically brutal and mentally demanding, says Jarrod Rink, CF Reese project manager and fellow team participant.
The event, now in its second year, saw 37 teams taking turns to ride 150cc farm bikes over a full 24-hour period, with no engine stops other than for refuelling. It ran from 5pm Friday to 5pm Saturday, with riders rotating 15-minute stints in daylight and one-hour stints overnight. The CF Reese team placed a very respectable 17th. “It was a fantastic team building experience for us,” says Jarrod. “You need to look after your team and your bike equally just to finish. Very proud to raise money for the Waikato Hauraki Coromandel Rural Support Trust.”

WELCOME TO NEW REGIONAL MANAGER CALLUM DIMOND
Masterlink is thrilled to introduce new Auckland Regional Manager Callum Dimond. Callum replaces Colin Kilpatrick, who retired in February after seven years of dedicated commitment to Masterlink.
“I'd like to make special mention to my old friend Colin, who was actually my apprentice manager back in 2015,” says Callum, a qualified plumber with nine years’ experience working at Quix Commercial in Auckland.
“He has shown me the Masterlink ropes, and I’ve met some great people through him. I thank Colin for building such a strong customer base for me to work with and wish him a very happy retirement.”
Callum was drawn to the role with Masterlink, as he is passionate about the trade and developing top-notch apprentices. “Masterlink has a very good name in the industry, and I look forward to collaborating with the team to provide high quality candidates to the PG&D trades, with a goal of completing them on time with the necessary skills and knowledge to become great tradesmen and women,” he says.
Brought up in Howick, East Auckland, Callum has lived in Cockle Bay for the past four years in the house he purchased with his wife Brittany.
Mad about sports, Callum is usually to be found at rugby training and games in the winter, or touch rugby in the summer. “You’ll also see me out at Whitford golf course some weekends (if my wife lets me!),” he says.

KEEPING HYDRATED
Hydration is important, even in winter. The safety team at NZ Safety Blackwoods has some top tips.
During winter, the cold and dry air can cause the body to lose more fluids than usual, leading to dehydration. We tend to drink less water during the winter months because we don’t feel as thirsty as we would during summer.
Replace essential electrolytes: It’s important to drink plenty of fluids throughout the day, and to replace essential electrolytes.
Dress appropriately: Dress in layers to keep warm and dry when working outside.
Take breaks: Take frequent breaks to rest and rehydrate. Monitor urine colour: Urine colour is a good indicator of your hydration level. If your urine is dark yellow or amber, you may be dehydrated and need to drink more fluids.
NZ Safety Blackwoods has over 100,000 products across engineering, tools, safety, workwear and more. Visit nzsafetyblackwoods.co.nz to find out more and view their catalogue.

With the launch of Nero Tapware in New Zealand, trade professionals now have access to a brand known for quality materials, cutting-edge design, and durability. Nero National Sales Manager Tony Shirley shares their approach to product development and commitment to the plumbing industry.
AUTHOR: JE T’AIME HAYR PHOTOGRAPHY: ROBIN HODGKINSON
he Nero showroom opened in Newmarket, Auckland, in October 2024 and spans 565sq m of minimalist style. Company owner Kevin Cheng was heavily involved in the open-plan design, which offers an immersive bathroom experience where visitors can experience the functionality of the tapware.
T“In addition to the boardroom, offices and the product displays, we have a shared space where designers, architects, builders and plumbers can do client consultations and colour matches,” says Nero National Sales Manager Tony Shirley. “The public are welcome to come in as well.”
The showroom’s striking design has even earned it a spot as a finalist in the New Zealand Commercial Project Awards 2024.
As part of its global expansion, Nero made a strategic decision to ensure that the complete Australian range is available to Kiwi customers. The company’s diverse product lineup is categorised into two main segments: premium brands and builders’ ranges.
The eight premium ranges focus on high-end residential and commercial applications, while the four builder’s ranges are perfectly suited to volume-build projects, providing well-priced options without compromising quality.
Tony and Tracy Shirley are excited to bring Nero Tapware to the New Zealand market.
Partnering with plumbers
With a showroom designed to showcase tapware aesthetics and function, Nero is equally focused on the professionals who install and recommend its products.
The company is committed to supporting the plumbing industry, both through product development as well as ongoing training initiatives.
“We’re actively involved with Master Plumbers, and have signed up as a platinum sponsor,” says Tony. “Master Plumbers’ reputation as the moral compass of the industry aligns with our values, and they play a key role in ensuring quality standards remain high.”
In addition to training, Nero provides extensive technical support, installation guides, and direct assistance for plumbers on-site. The company welcomes feedback from tradespeople, using their insights to refine product designs and improve installation processes.
“When you manufacture your own products, you can make adjustments quickly,” explains Tony. “If plumbers tell us there’s a way to make installation easier, we listen.”
High-performance tapware
Plumbers have traditionally recommended brands they trust, but in the age of social media, there’s been a shift towards customer preferences being increasingly driven by aesthetics and price. As a result, Tony believes that New Zealand’s tapware industry has seen an influx of low-quality imports, often with limited warranties and little to no after-sales support.
“Anyone can import tapware from China or India, but that doesn’t mean it meets local standards,” he warns. “There’s no policing of these products, and many don’t have adequate warranties. Our goal is to set the standard for quality and reliability.”
Nero’s aim is to offer stylish, high-performance tapware that tradespeople can confidently stand behind. “A cheap tap may save money upfront, but if it fails in a year and you have to pay a plumber to reinstall a replacement, you haven’t saved any money at all,” Tony says.
Beyond product longevity, consumer health is also a priority. With lead free certification now becoming the benchmark, Nero is
at the forefront in ensuring all drinking-water tapware meets the highest safety standards.
“We’ve already moved away from traditional DR brass to a formulation with the lowest lead content possible,” says Tony. “Since there’s no risk of leaching, it ensures safer drinking water for consumers.”
Unlike some generic imported products that lack proper certification, all Nero tapware is AS3718 and WELS certified and every mixer that needs to be lead free will bear a stamp in the future, confirming compliance with New Zealand standards.
Rigorous quality control
Designed in-house in Australia and manufactured in the company’s own 35,000sq m, 322-staff factory in China, Nero controls the production process from design to delivery. As such, quality assurance is something Nero takes seriously. Every product undergoes multiple layers of testing before it reaches the customer.
“Our tapware is tested for lead content, structural integrity, and leak prevention,” Tony explains. “With outdoor products, we conduct 200H salt spray tests to ensure colour stability over decades. When a product leaves the factory, you can be sure it has been meticulously tested and inspected.”
The brand also employs the latest Physical Vapor Deposition (PVD) technology for its finishes, ensuring long-term durability and resistance to wear. PVD is more resistant to corrosion and maintaining the colour for longer and is more environmentally friendly than traditional coating processes.
It’s thanks to this meticulous quality control that the company confidently offers an industry-leading warranty structure. “Our builder’s ranges come with a 15-year warranty on cartridges and 10 years on all parts and colours, while our premium ranges are 25 years on all parts and colours,” says Tony. “Few brands extend that kind of coverage, but we stand behind our products. It’s peace of mind for plumbers too. Knowing that a product meets stringent standards and carries a solid warranty makes it easier for professionals to specify Nero in their projects.”
The new Nero Tapware showroom in Auckland incorporates a shared space where plumbers and other construction professionals can carry out client consultations and colour matches.
New product lines
Two exciting new Nero product lines launched at Design Week in March: Zen and Serenity. The Zen range is designed for both indoor and outdoor use, crafted from 316L marine-grade stainless steel, and comes in brushed nickel, gold, and bronze as well as graphite hues – all backed by a 25-year warranty. Zen includes outdoor taps, mixers, and showers, making it ideal for coastal homes and poolside installations.
“Our outdoor products are designed to withstand harsh conditions,” says Tony. “New Zealand is a coastal nation, so having tapware that stands up to the elements is crucial.”
The Serenity range, meanwhile, leans into the growing demand for natural aesthetics and sustainability. Featuring marble handles paired with lead free tapware, the collection allows customers to mix and match finishes like brushed bronze, brushed gold and gunmetal.
Supporting aged care sector
One of Nero’s most innovative product lines is Mecca Care, a range designed for aged care facilities and for homeowners looking to future-proof their living spaces. Offering colour-coordinated grab rails, support rails, and toilet aids, Mecca Care provides a stylish alternative to traditional accessibility solutions and complies with NZS4121:2001 Design for access and mobility
“This is one of the fastest-growing sectors globally,” explains Tony. “People want stylish and functional safety solutions in their homes and retirement villages. Our range offers up to 150kg weight capacity and comes with a 25-year warranty.”
Given that bathrooms are the most common location for household accidents, Mecca Care aims to combine safety with design-led aesthetics. The range is already seeing strong uptake, particularly in high-end developments.
Sustainability commitment
Beyond its commitment to product longevity, Nero is also making strides in sustainable packaging. The company is removing gloss and print from its boxes to ensure they are fully recyclable.
“We’re moving towards 100% recyclable internal packaging as well,” Tony notes. “No plastics, no unnecessary waste. Even our trade show displays are designed to be recyclable.”
With its focus on quality, sustainability, and industry support, Nero is set to become a leading force in New Zealand’s tapware market – backed by an unwavering commitment to plumbers and tradespeople.

UNDER PRESSURE
The New Zealand industry must do more to align with Australia in ensuring the safe use of jetters for pressure washing, as Ian Pauley explains.
AUTHOR: IAN PAULEY, DRAINQUIP NZ
Every year in New Zealand, 720 people on average are injured using pressure washers or jetters, according to ACC. Most injuries are just flesh wounds –someone, say, taking a bit of skin off his toes as he sweeps past with the lance while water blasting his ute deck in jandals.
However, the higher pressure units we use in our industry are potentially lethal, and those who’ve been in the job a while have all had close shaves and stories to tell. Like when the jetter found its way out of a broken drain and came up through the lawn like a space shuttle to Mars. This looks (and in most cases is) funny at the time, unless young Johnny happens to be riding his trike on the front lawn at the same time.
I once bought a used jetter (450LPM @ 3,000psi) from a major New Zealand company. They were selling it as a kneejerk reaction to the fact that its sister unit, based
in Rarotonga, had tragically killed one of their workers, who had started it up on the ground to check something out. The flusher head, weighing around 10kg, reared up like a snake, swung around and, with full force, struck him in the head, killing him instantly.
Class B unit training
Although we share joint standard AS/NZS 4233.1:2013 High pressure water jetting systems - Part 1: Safe operation and maintenance, we don’t apply it here like the Aussies. Is it because Kiwis are tougher and brighter than the Aussies?
The standard breaks pressure washing down into two categories:
Class A – under 5,600 bar lpm (multiply pressure in bar by flow)
Class B – over 5,600 bar lpm.
Basically, Class A is less pressure and volume, such as a typical domestic pressure washer. A Class A product does not require any qualification or training, and anyone can use them. You might just lose a bit of skin off your toes.
Class B is the higher pressure and volume units that are generally more commercial or industrial, of the type we plumbers and drainlayers use. To use a Class B machine, you need to sit a course and become qualified. It’s mandatory in Australia, yet for some reason we don’t enforce this standard here.
Here’s a fact: depending on the nozzle being used, water leaving the nozzle can travel at incredibly high speeds. For example, for every 1,000 PSI, the water leaving the nozzle may be moving at 110mph. When you consider that a standard jetter is 3,000-4,000 PSI, that’s a water speed of between 330-440 miles per hour.

When the team at building firm Iconic Construction was seeking a plumber to work on their first 3D-printed house build, Plumbing & Gas Works’ approach was so impressive, they sought no other quotes. NZ Plumber talks to Iconic founder Nick Lane about the making of this Hamilton showhome.
AUTHOR: VICTORIA CLARK
Installing plumbing in a 3D-printed house is certainly different from a traditional timber-framed, gib-walled construction, says Iconic Construction founder Nick Lane – but the job is no more difficult. “It’s about creating the finished look, such as using powder-coated aluminium boxing to conceal piping on the internal walls. They can easily become stylish design features.”
As Iconic Construction was preparing to turn The Architecture People’s 3D house plans into a reality in Hamilton’s Brymer Heights, a solution-focused pitch from Waikato firm Plumbing and Gas Works was accepted without hesitation.
Kitchen, bathroom, toilets and laundry plumbing are standard in a house with walls that have been churned out from a 3D printer robot. The waste system, too, is the traditional pipes-through-the-floor method. The big difference is in how and where the pipes are installed to bring water into the building.
“In a 3D build, the pipes are fed down the walls inside a bathroom, kitchen or
laundry from the top, before the ceiling is put in place,” explains Nick. “There’s no timber framing in the walls, so plumbers won’t need to lag pipework – there’s no drilling holes through nogs and dwangs. That means the workflow is faster; there’s a greater turn-around of jobs.”
“There’s no timber framing in the walls, so plumbers won’t need to lag pipework – there’s no drilling holes through nogs and dwangs."
“The
superior option”
The goal for Nick and his business partner, Iconic Construction’s general manager Johnny Gordon, is to build as many 3D-printed homes as it takes to make them the norm. “Having worked with timber all my working life, I’m convinced 3D-printed housing is the superior option,” says Nick, who discovered the remarkable system three
years ago when he saw outdoor furniture that had been made on a 3D printer.
Intrigued, he quizzed the owner, then announced to his building team: “We’re changing all the pre-cast concrete walls on our latest project to 3D-printed walls.” That project, the Creative Childcare Centre, became the Southern Hemisphere’s first commercial building to be created from a 3D printer.
In collaboration with QOROX – the entrepreneurial business that brought 3D printing technology to New Zealand in 2020, the Iconic team created the Brymer Heights house in 99 days: its 36 interior and exterior walls literally rapid-churned out of a 3D printer over 24 hours.
Unique form of concrete
Nick and Johnny jokingly call the unique form of concrete ‘the printer’s ink’.
“QOROX creates the mix, using 80 per cent locally sourced ingredients, and 30 per cent of the dry product is only available from overseas,” Nick explains. “It is superfast drying, setting in three minutes.”
Hamilton’s Brymer Heights showhome, built in 99 days with 3D printing, is open between 10am and 2pm
This 3D-printed showhome at Hamilton's Brymer Heights subdivision was completed in 99 days – its walls
In a 3D build, the pipes are fed down the walls inside a bathroom, kitchen or laundry from the top, before the ceiling is put in place.
The printer’s arm moves in a circular motion, evenly ‘printing out’ textured layers of the special concrete. The bonus of creating entire walls in layers is the capability it has to create curved walls. The Hamilton showhome has one arty feature wall, resembling a water drop’s ripple on a pond.
The strength of these walls is phenomenal, too. Nick says 3D printed walls are more than four times stronger than a home built with timber and GIBboard, meaning a 3D home has a lifetime of hundreds of years.
“We’ve recently brought in another 3D printer from the Netherlands, basing it in Christchurch, but we’re aiming to eventually have a printer in every main city throughout New Zealand. To plumbers, I’d say, ‘At some point a 3D printer will appear in your region, so if you want to get involved, keep an open mind’.”
The Brymer Heights showhome is open between 10am and 2pm weekdays, and by appointment on weekends. Check out: www.iconicconstruction.nz/iconic3d
The waste system is the traditional pipes-through-the-floor method.
3D printed walls are over four times stronger than a home built with timber and GIB-board, according to Iconic Construction’s Nick Lane.

EECA PARTNERSHIP SUPPORTS
HOME ENERGY EFFICIENCY
Master Plumbers is teaming up with EECA (Energy Efficiency and Conservation Authority) to help New Zealanders learn about the advantage of energy-efficient technologies like hot water heat pumps.
Over a third of water heating systems in New Zealand homes are more than 10 years old, according to consumer research by EECA last year. For an appliance with a 15-year life expectancy, this presents a significant opportunity in the coming years for households to save on their energy bills –if they choose the right replacement.
Plumbers are typically the first port of call when an old hot water system bites the dust, acting as trusted advisors when it comes to replacement purchasing decisions.
In late 2024, Master Plumbers and EECA teamed up to survey trades professionals to gauge how the industry is placed to support consumers with new, more energy-efficient technologies like hot water heat pumps.
Information and training
Findings showed that New Zealand’s electricians and plumbers perceive the rate of change in the industry to be increasing steadily, driven in part by customer demand for emerging technologies that improve energy efficiency.
Most are finding it difficult to upskill at the rate required, though it is seen as an important part of the job, however long they’ve been doing it. There was real motivation for more information and support to help industry professionals keep up with changing, and increasingly complex, technology.
EECA and Master Plumbers saw this as a great reason to partner up and work together to support the industry.
“More than 90 per cent of plumbers say their customers view them as trusted
EECA Chief Executive Marcos Pelenur and Master Plumbers Chief Executive Greg Wallace have signed an MOU to support energy efficiency across New Zealand’s homes and businesses.
EECA’s Switch on Efficiency campaign explores the advantages of energy-efficient technology like rooftop solar, induction cooktops, hot water heat pumps and EVs.
advisors, so supporting them with the most up-to-date evidence and training will ensure they are best equipped to help their customers maximise the benefits of innovative technologies,” says EECA Chief Executive Marcos Pelenur.
The aim for the partnership is to be really pragmatic and helpful, so expect to see more EECA information here in NZ Plumber, and through other Master Plumbers channels in the coming year.
Homeowner support
Alongside working with the industry, EECA is supporting customers with home energy decisions through the Switch on Efficiency information campaign, under its Gen Less platform.
Fronted by architect and Grand Designs NZ host Tom Webster, the campaign explores the advantages of technology like rooftop solar, induction cooktops, hot water heat pumps and EVs. A hand-crafted, 1:18 scale model of a house provides the setting for these energy-efficient upgrades.
One tool that you may find helpful when talking to customers is the home energy savings calculator on the Gen Less website. Simply put in a few details about your household, and the calculator will show you how much you could save on energy bills if you were to invest in more efficient technology. Looking past the higher up-front
cost of more efficient technology can be a challenge, so EECA hopes this tool can help people to see the long-term benefits and cost savings that come from energy efficiency

Hot water heat pumps could save the average household $284 in energy costs each year, according to EECA modelling.
EFFICIENT WATER HEATING WITH HPWH
Providing household cost savings and environmental benefits, hot water heat pumps are growing in popularity in New Zealand homes. NZ Plumber talked to suppliers about their available technologies.
Hot water heating makes up about a third of an average household’s energy bill, on average. Costs vary depending on what technology is used to heat water, as well as household demand.
Hot water heat pumps are highly energyefficient compared to traditional electric hot water cylinders or gas. This means they are cheaper to run and can be particularly costeffective for households that use a lot of hot water. The technology also produces fewer emissions than water heated with fossil fuels.
Hot water heat pumps work by pulling heat from the air using a heat pump mechanism and transferring that heat into water stored in a cylinder.
Stiebel Eltron
Stiebel Eltron has been at the forefront of heat pump technology since 1976, delivering energy-efficient solutions for hot water heating. With over 15 years of experience supplying heat pumps in New Zealand, the company understands the needs of plumbers seeking reliable, easy-to-install systems.
The WWK Hot Water Heat Pump is designed for seamless integration, offering an all-in-one unit that can be plumbed like a standard cylinder. Its plug-and-play setup simplifies installation for plumbers, making it an efficient and hassle-free choice for both new builds and retrofits.
Designed for low maintenance and quiet operation, the WWK unit provides a long-lasting, energy-efficient alternative to traditional water heating. It is also solar PV ready, allowing homeowners to maximise renewable energy use.
For plumbers wanting to expand their expertise, Stiebel Eltron offers training sessions and a hands-on showroom in Auckland, showcasing the latest innovations in energyefficient hot water solutions.

Rheem
Heat pump water heating has changed the water heating industry, leading to tangible savings and a reduction in the household’s overall carbon footprint. Rheem heat pump water heaters draw outside air into the cylinder through inlet louvres. An evaporator absorbs heat from this air and transfers it to the water through a heat exchanger. This process continues until the required water temperature is reached, providing readily available hot water for the household.
Even on cloudy or cold days, Rheem’s systems extract heat from the surrounding air. While Rheem heat pump hot water heaters operate efficiently in temperatures from -5°C to 43°C (-6°C for the AmbiPower range), they will stay functional in all conditions thanks to the backup element. They also feature wrap-around microchannel heating technology for uniform, faster water heating, making them suitable for all New Zealand climates.
Dedicated to creating eco-friendly solutions, Rheem is proud to provide two ranges of heat pump water heaters for the NZ market: the AmbiHeat and the AmbiPower. Both provide exceptional savings and durability, with Rheem’s latest heat pump water heater – the Rheem AmbiPower 280e – even saving you over 70% of your water heating energy costs compared to traditional electric water heaters.
MM Brands
The new Dux Ecosmart Pro-Series heat pumps are ideal for large hot water users looking to save on energy bills. They feature a powerful compressor capable of heating a full 270L tank in only 3.5 hours*. Even during the colder months, when the ambient temperature during the day is around 10°C, it can still heat a full tank in five hours.
Despite being powerful, they’re still very quiet and efficient, with a high COP of 4.7^ – well over four times more efficient than standard electric water heaters.
Heat pumps make even more sense when heating during the day, or operated at times to correspond with periods where PV power is being generated (if such a system is fitted). If heating using excess power from your own system, or during concessional tariff periods, you’ll really supercharge your energy savings. You can access two timer settings per day through the touch screen controller, or simply set and forget for efficient heating all year round.
There are different operating modes: heating mode, boost mode and vacation mode. In heating mode, the default setting, the heat pump will heat water to 60°C to complete the heating cycle. In boost mode, the heat pump and heating element operate simultaneously for even faster heating. This is great for when people are staying over, or during very cold winter conditions when more hot water is used. Vacation mode is perfect for times away from home when you don’t need to heat the water.
The Dux Pro-Series heat pump features an external wraparound copper condenser, making it suitable for use in a broad range of water qualities. And with environmentally friendly R290 refrigerant, it has a low global warming potential of less than three.
The heat pump includes a backup element for single shot boost applications, or for heating during extreme ambient temperatures. The element turns on automatically if the temperature drops to below -5°C when heating is still required. It can otherwise be manually activated through the boost mode. For very cold conditions, the heat pump also includes an active defrost function, and an additional function to prevent water in the tank from freezing.
Dux Ecosmart Pro-Series heat pump’s high heating capacity means shorter heating cycles, fewer heating hours and ultimately longer service life. The polymer materials used in the heat pump are UV stabilised to ensure they won’t turn brittle in the sun over time. And with the inclusion of fire retardant, they’re much safer too.
Pro-Series heat pumps come with a five-year warranty on both the tank and refrigeration system.

KEEPING IT UPRIGHT: Seismic
Cylinder Restraints
Seismic cylinder restraints are a vital consideration for New Zealand’s plumbers, as Aqualine explains here.
New Zealand’s location on the Pacific Ring of Fire means earthquakes are a constant reality. As plumbers, you play a critical role in ensuring the safety and resilience of buildings – and a crucial, often overlooked, aspect of earthquake preparedness is securing hot water cylinders.
A toppled cylinder can cause significant damage, from scalding water spills and structural issues to the disruption of essential water supplies. This is where seismic cylinder restraint kits become indispensable, and where your expertise is essential. These kits are designed to prevent hot water cylinders from falling over during seismic activity. They achieve this by firmly anchoring the cylinder to the building’s structure – typically a wall or the floor. Think of it as a seatbelt for the cylinder, keeping it safely in place when the ground starts shaking.
Why so important?
The dangers of an unrestrained hot water cylinder during an earthquake are numerous:
Safety hazard: A ruptured cylinder can release scalding hot water, posing a severe burn risk.
Property damage: The sheer weight of a falling cylinder can cause significant damage to the surrounding structure.
Water supply disruption: A toppled cylinder can disrupt access to potable water just when it’s needed most. Following a major earthquake, municipal water supplies may be compromised, making the water stored in the cylinder a vital resource.
Excerpt from G12/AS1 Fig 14: Seismic restraint of storage water heaters 90-360 litres
Extra centre strap for water heaters exceeding 200 litres.
Safe tray to comply with Paragraph 5.2.3.
Choosing the right kit
See G12/AS1 Fig 14: Seismic restraint of storage water heaters 90360 litres (below).
Kit selection hinges on several factors:
Cylinder capacity: Generally, two straps suffice for cylinders under 200L, while three are mandatory for larger cylinders. Always consult the manufacturer’s instructions, as some smaller cylinders may also require three straps.
Height: Cylinders over 12m above ground level require an additional centre strap (G12/AS1 Fig 14, Note 1).
Strap placement: Ideally, straps should be within 100mm of the cylinder’s top and bottom. Alternative placement guidelines (within the top/bottom 25% with additional central straps as specified in G12/AS1 Fig 14, Note 4) may apply if this isn’t feasible. Maximum: No more than four straps are ever required (G12/AS1 Fig 14, Note 5).
Aqualine, a leading NZ supplier, offers galvanised and stainlesssteel seismic cylinder restraint kits to suit various needs. While galvanised steel is robust, stainless steel offers superior corrosion resistance, ideal for coastal areas.
Meeting the standards
The effectiveness of a seismic restraint system depends heavily on the quality of its components. The thickness and material are key factors in ensuring the system’s strength and ability to withstand earthquake forces, meeting the stringent requirements of G12/AS1, NZS 1170.5 and AS/NZS 4603.
Notes:
Storage water heaters to be restrained with 25mm x 1mm galvanised steel straps tensioned when fixed in place.
1. An additional centre strap is required where a storage water heater is located more than 12 m above finished ground level.
2. Additional timber framing may be required in retrofit situations to ensure adequate strap fixing is available.
3. Straps shall not be installed where they clash with water heater inlets, outlets or controls.
4. Where the 100 mm maximum strap distance from the top or bottom of the storage water heater cannot be achieved, straps may be placed within the top and bottom 25% with one additional strap placed centrally for water heaters < 200 litres, and two additional evenly spaced straps for water heaters 200 - 360 litres.
5. A maximum total of four straps are required when complying with both Note 1 and Note 4.
Generally, two straps suffice for cylinders under 200L, while three are mandatory for larger cylinders – but always consult the manufacturer’s instructions.
Aqualine understands this, which is why their kits feature 1mm thick strapping. This commitment to quality gives you, the installer, and your clients confidence in the system’s performance.
Installation is key
As experienced plumbers, you know that while having the right kit is essential, proper installation is paramount. Seismic cylinder restraints should always be installed by a qualified and licensed plumber.
Your expertise is crucial in assessing the site, determining the correct kit configuration (including the appropriate number of straps, considering height and placement requirements), and ensuring the system is installed according to the relevant building codes and standards.
You will also be able to determine if additional timber framing is needed for adequate strap fixing (as per Figure 14, Note 2). Straps should not clash with water heater inlets, outlets, or controls (Figure 14, Note 3). A poorly installed restraint system is as good as no restraint system at all.
Peace of mind
Investing in a quality seismic cylinder restraint kit from a reputable supplier and having it professionally installed is an investment in safety and peace of mind for your clients. It’s a proactive measure that can protect families, property, and access to essential water supplies in the aftermath of a seismic event. Don’t wait until disaster strikes – discuss these options with your clients and ensure their homes are prepared. Your proactive approach will reinforce your reputation as a trusted and safetyconscious professional.

What are the ‘worst wastes’ in construction and how to avoid them? The Environmental Innovation Centre provides guidance.
AUTHOR: ENVIRONMENTAL INNOVATION CENTRE (EIC)
Finding huge volumes of wasted soft plastics in the skip is never good – but at least it provides an opportunity to investigate the ‘Avoid, Reuse or Recycle’ options (see Figure 1).
Least
As this simple waste management pyramid shows, the best approach is to avoid producing waste in the first place. It’s great if you can find time to talk with your suppliers about reducing the amount of unnecessary waste reaching your site – some packaging, for example.
However, if plastics are unavoidable, it is preferable they are the kind that can easily be reused or recycled.
‘Worst wastes’: Top 3
Sadly, some items can’t be recycled due to their physical structure, material type or lack of local recycling capability. Hopefully you can use this guide to avoid these waste streams coming to your site and the landfill disposal costs they could incur.
1. Woven plastics
Any plastics with a weave cannot be recycled, as they are too difficult to shred and granulate into smaller pieces (see Figure 2). Strapping is usually tangled, may have metal buckles on it, and is often woven, as shown by the PP strapping in Sample 4. Sample 5 shows polyethylene terephthalate (PET) strapping, which can’t usually be recycled. Most PET recyclers in New Zealand only accept PET from food and drink containers (eg, meat trays, drink bottles).
Figure 1: Waste management pyramid.
Figure 2: (1) Woven PP timber covers; (2) Woven LDPE sheets; (3) Woven LDPE clear sheets; (4) PP strapping, woven, tangled and with metal buckles; (5) PET strapping.
Landfill
2. Composites
Composites are plastic materials made of various types of plastic or other materials, which makes them much harder to recycle. As they are not single-stream wastes (see below), they must either be disassembled for recycling or go to a multi-stream recycler. The extra time required for disassembly means these items are less likely to be recycled.
Examples in the construction industry are any products that incorporate paper, or cable reels made of multiple plastic types or materials (see Figure 3).
RECYCLING – SINGLE STREAM VS MULTIPLE STREAM
Not all areas of New Zealand are equally blessed with reuse and/ or recycling capabilities. You may not have much choice in your region – but if you do, consider what is going to happen to your waste once it leaves you.
It’s ideal to choose a recycler that recycles one type of plastic (single waste stream) into similar high-quality products, instead of mixing many different types of plastic (multiple waste streams) and downcycling them into less valuable products. Recycling a single type of plastic keeps it purer, maintains its value and makes it easier to recycle again at the end of its life.
3. Backing film
The backing film of some adhesive products, such as building paper, often has silicon in it, which limits its recyclability. This produces a large amount of waste, as the backing tape has an equal surface area to the product itself (see Figure 4).
It is important not to mistake these products for low-density PE (or LDPE) and/or shrink wrap, which can both be recycled.
Some backing tapes are paper-based with a plastic coating. These products tear easily and cannot be recycled by either paper or plastic recyclers.
How can we tackle the worst wastes?
EIC estimates these non-recyclable plastics account for about 30% of all plastic waste coming from a typical Auckland construction site. This percentage will vary according to the location of the site and whether recyclers are available in the region.
For products that cannot be recycled, the best approach is to avoid using them or switch to recyclable alternatives that create less waste (for example, avoiding woven timber covers). This is not always possible, as a better alternative may not yet be available.
In some cases, contacting suppliers to request minimal or no packaging is a good solution. Many suppliers are working to replace non-recyclable products with recyclable ones – something EIC has actively been trying to encourage.
The good news is that, as New Zealand’s recycling industry continues to expand, opportunities for recycling various products are likely to increase. For instance, the future introduction of adequate shredders for non-food PET could enable PET strapping to be recycled.
EIC is also investigating ways to improve the movement of waste from site to recycler and improve the recyclability of construction waste in the future.
By taking these steps, we can reduce the amount of plastic waste that New Zealand construction sites send to landfill

AI FOR BUSINESS
Scot Pearce uses AI at his Water to Waste business and reports on his experience here (with a little help from ChatGPT).
AUTHOR:
RSCOT PEARCE
unning a plumbing and drainage business is about more than just pipes and fittings; it’s about problem-solving, efficiency, and staying ahead of the game. In today’s fast-paced business environment, technology plays a bigger role than ever, and one of the most useful tools I’ve adopted in my daily workflow is ChatGPT.
At first, I was sceptical. Could AI really add value to a trade-based business like mine? But after integrating it into my daily work life, I quickly realised it’s like having an extra team member; one that never takes a break and always has an answer.
Here’s how I use ChatGPT to boost efficiency, save time, and improve my business operations:
1. Quick answers & research
When I need technical information, industry trends and ideas, or clarification on regulations, ChatGPT helps me find answers fast. Instead of trawling through multiple codes and websites, I can get a concise, well-explained response in seconds; whether it’s about new building code updates, plumbing innovations, or business management strategies.
2. Content creation & communication
Writing isn’t every tradeperson’s strong suit, but running a business means constant communication; from customer emails and social media posts to staff memos and marketing content. ChatGPT helps me craft professional, clear, and engaging messages. It also fine-tunes my BNI presentations and
business proposals – and even helped me write this very article you are reading in NZ Plumber magazine.
3. Business strategy & planning
From drafting business plans to brainstorming growth strategies, ChatGPT helps me organise my thoughts and structure ideas. I’ve even used it to refine my pricing models, customer service policies, and hiring strategies. It’s like having a business coach on demand.
4. Customer service & FAQs
When customers ask similar questions (eg, “How much does a hot water cylinder replacement cost?” or “Do you offer finance options?”), ChatGPT helps me create standardised content for my website, emails, and phone scripts; ensuring consistent, professional service every time.
5.Time-saving admin support
From summarising meeting notes to drafting contracts and policies, ChatGPT helps me tackle admin work efficiently. It’s also useful for generating job descriptions, interview questions, and staff wellbeing and training materials, which has been a game-changer for our business.
Is it replacing people? No, it’s helping them.
The question I always get is: “Is AI taking jobs?”
The reality is, ChatGPT doesn’t replace people; it empowers them. My team still does the hands-on work, but AI helps us communicate better, make smarter decisions, and focus on what really matters; serving our customers and growing our business.
If you’re not yet using ChatGPT (or similar AI tools) in your business, give it a go! Whether it’s for writing emails, generating quotes, or brainstorming ideas, you might be surprised at how much time and effort it saves you.
Technology isn’t replacing good tradespeople; it’s helping us work smarter. And in this industry, that’s always a win.
Business smarts
Once he got over his initial scepticism, Scot Pearce started using ChatGPT to add value to his business.
BUSINESS RISK Plan Creation: Part 3
In the final of this three-part series on business risk analysis, Trevor Slater sets out ways to minimise or mitigate the identified risks to your business.
AUTHOR: TREVOR SLATER, SIMPLY RESOLUTION
The first two parts of this series guided you through Steps 1 and 2 of the business risk analysis process:
1. Identifying the risks to your business
2. Rating their likelihood and impact.
This brings us on to the third and final step: mitigating and controlling these risks.
Step 3: Risk mitigation and control
Risk mitigation is all about reducing the likelihood and impact of risks to your business to a level that is acceptable. You cannot remove all business risks. If that were possible, every business would be a resounding success. Being ready if a risk occurs is the key to not losing your business.
There are a number of ways to reduce or mitigate your business risks. These include:
Control – Take actions to reduce or minimise the likelihood and/or impact of the risk
Avoid – Don’t undertake the activity in any form
Accept – Out of your control/cost to control too high
Transfer – Have someone else undertake the task, such as outsourcing or insurance.
Control is the most used risk reduction method.
Risk control example
Let’s look at control in terms of the human risk we identified and rated in the previous two articles in the series: the only registered gasfitter in your business is injured and unable to work for some time.
Taking actions to control the risk is the best way to ensure the gasfitting division of your business continues with minimal disruption.
Employ a second gasfitter
Train someone else in your business to become a qualified gasfitter
Double check your health and safety plan
Have income protection insurance for your gasfitter
Be aware of alternative gasfitters you could contract to do work for you.
Alternatively, you could avoid the risk by not offering gasfitting services at all. Or you could transfer the risk by contracting a gasfitting group to do the work for you.
Disaster recovery plan
In this beautiful country of ours, any risk plan creation must include natural disasters – earthquakes, flooding and storm damage, to name just a few.
You need a response plan, so you can continue to operate or quickly resume business.
A disaster recovery plan (DRP) takes a documented, structured approach, with instructions for responding to unplanned incidents.
It will guide you step-by-step through the precautions you need to take to minimise the effects of a disaster on your business.
There are many online guides to help you create your own DRP.
Top tips to creating your risk management plan
Break down the process into smaller chunks, such as just identifying the risks as step one. Trying to do all the business risk steps in one go is very hard.
Put some regular time aside each week to do part of the risk analysis and mitigations.
Start your risk mitigation by addressing the highest rated risks first. These are the ones most likely to happen and to cause the most damage.
Document your risk plan and make sure you share it with all your team.
Ensure you have a disaster recovery plan (see right), and all your team know their roles if a disaster happens. Start the process now. You never know when a risk will happen and, if you are not prepared, it could cost you a lot.
One final point. Risk analysis and risk plan creation can be challenging. If you’re finding it too hard, get help. There are numerous organisations that can provide great risk analysis and mitigation plans. Yes, plans do cost money but, like insurance, they provide peace of mind if disaster strikes.

MMEDICINAL CANNABIS workplace safety
A
new guide for employers and employees answers commonly asked questions on the use of medicinal cannabis in the workplace. Here, the New Zealand Drug Foundation highlights a few key areas it covers.
AUTHOR: SARAH HELM, EXECUTIVE DIRECTOR, NEW ZEALAND DRUG FOUNDATION
y uncle and grandfather were plumbers, and I am a medicinal cannabis patient – I take non-impairing CBDisolate for arthritis. So, I am pleased to have the opportunity to share with you the work we have been doing to help employers and workers navigate medicinal cannabis in the workplace.
Since New Zealand’s medicinal cannabis scheme took effect in 2020, we’ve fielded a lot of calls from employers trying to navigate safety, fairness, and legal obligations. We’ve also heard from many workers hesitant to disclose their medicinal cannabis use because their workplace’s policies are unclear on what the consequences would be.
And so, with the help of Construction Health & Safety NZ (CHASNZ), Dentons, Rothbury, and Māori & Pacifika Trades Training, we’ve developed a new guide, Medicinal cannabis: A guide for employers and employees.
We have tried to make it practical for both employers and employees. The guide provides an overview of medicinal cannabis and why it’s prescribed, sets out employers’ and employees’ rights and responsibilities, and suggests practical changes to workplace policies and procedures to manage disclosure of medicinal cannabis use and workplace impairment.
Q: Medicinal cannabis vs illicit cannabis – what’s the difference?
A: In our guide, medicinal cannabis refers to pharmaceutical products prescribed by a doctor.
Some products (like CBD isolate) do not contain any THC and have no intoxicating effects at all. Other products contain a specific amount of THC, which is the potentially intoxicating component of cannabis, and the amount varies by product – some contain just a trace.
Illicit cannabis, by contrast, can contain widely variable amounts of THC and potential contaminants.
Both illicit cannabis and medicinal cannabis products containing THC will be detected in a urine drug test, even if taken as prescribed. Detection of either substance in a drug test does not prove impairment, as THC can stay in someone’s system for many days after use. A patient who uses medicinal cannabis may not be impaired at all, or not impaired during work hours.
Q: Why is medicinal cannabis prescribed?
A: People are prescribed medicinal cannabis for a range of conditions, including chronic pain, insomnia, anxiety, or nausea from cancer treatments.
People with a prescription for medicinal cannabis may sometimes find it preferable to traditional pharmaceuticals, especially if they have experienced unwanted side-effects and poorer quality of life from standard medical treatments.
A patient who uses medicinal cannabis may not be impaired at all, or not impaired during work hours.
Q: What impact can medicinal cannabis have on workplace safety?
A: Because THC can impair coordination and judgment, employers rightly worry about potential hazards.
While drug tests might be helpful for some employers, on their own they do not measure impairment. A positive test means THC was present in the system at some point, but it does not guarantee a worker is impaired at the time of testing.
Impairment can occur for a range of reasons: stress, fatigue, injuries, other medicines, other substances, alcohol and the like.
That’s why our guide encourages a holistic approach to safety. Practical steps include:
Clear policies around prescription medication disclosure
Open communication to ensure staff can confidently report impairment and relevant medication use
Where feasible, using impairment detection (eg, cognitive or motor skill apps) rather than relying solely on drug tests.
Q: What are the key rights and responsibilities for both parties
A: The guide goes into lots of detail about the many rights and responsibilities employers and employees have across various legislation.
Importantly, under the Health and Safety at Work Act 2015, employers must take reasonably practicable steps to eliminate

or minimise risks, including any impairment. At the same time, employees (and subcontractors) have a responsibility to work safely, take medications as directed, and to inform their employer if they are feeling impaired while at work.
Q: What practical steps can businesses take to ensure fairness and clarity?
Update policies and employment agreements: Consult with employees to update or develop processes for disclosing impairment and prescribed medications, and how any testing will be handled. The guide has a useful policy template and process flowchart.
Focus on impairment: Consider taking a broad view of potential impairment risks, regardless of the cause.
Create an open environment: Build trust so that employees disclose relevant medications.
Seek expert advice: If you’re unsure about legal obligations, talk to an employment law specialist.
While medicinal cannabis in workplaces can be a tricky topic, it needn’t be a stumbling block – especially for trades reliant on maintaining robust health and safety. In fact, many workplaces may find this is a useful opportunity to look at their whole approach to impairment.

Prequal advantage
Prequalification is worth considering if your business is looking to secure specific contracts.
Prequalification is becoming increasingly popular with companies wanting to expand their work opportunities. It involves completing an assessment that demonstrates your company meets industry standards by providing evidence in key areas such as policies, incident and injury reporting, and worker training and engagement. Many principal contractors and organisations, including government agencies, infrastructure and utility providers, require businesses to complete prequalification prior to engagement. Having a prequalification certificate can set you apart from competitors and increase your chances of securing the work. Beyond winning contracts, prequalification can serve as a valuable internal tool. It can be used as a proactive way to identify and address any gaps in your company policies and procedures,
ensuring your business meets best practice in health, safety, training and other responsibilities.
Before beginning, it is important to do your research, as there are different prequalification schemes. Choose one that suits your business. What type of work do you want to secure, and what are the requirements of potential clients? Some prequalification schemes allow principals and clients to access a database of approved contractors, which can increase your visibility and bring new opportunities directly to you.
Completing any prequalification does require time and effort. Instead of scrambling to meet requirements at tender time, being prepared can bring opportunity, improve operational standards and give you a competitive edge.

Significant changes have been introduced to the Accredited Employer Work Visa, Job Check, and accreditation requirements, as law firm Duncan Cotterill outlines here.
AUTHOR: NICKY ROBERTSON, SPECIAL COUNSEL, DUNCAN COTTERILL
ACCREDITED EMPLOYER WORK VISA (AEWV)
CHANGE #1:
Median wage no longer a requirement
As of 10 March 2025, the median wage is no longer a requirement under the AEWV immigration instructions. Employment agreements only need to stipulate an hourly rate that is at or above the minimum wage. However, the employee must not be paid less than the market rate for the offered role.
EXAMPLE
An employer offers the hourly rate of $27 per hour to an experienced plumber with 10 years’ experience. The Government careers website indicates that the rate of pay for plumbers, gasfitters and drainlayers is a range from $23 to $53 per hour. Immigration New Zealand (INZ) may raise concerns that $27, whilst above the current median wage, is not a market rate for a plumber with significant experience.
CHANGE #2:
Salary/wages in the employment agreement submitted with an AEWV application
The salary/wages in the employment agreement submitted with the AEWV application can be less than that in the Job Check, as long as the Job Check was approved on or before 9 March 2025, and the new wage/salary is at or above the minimum wage and is a market rate.
EXAMPLE
An employer applies for a Job Check setting out the minimum hourly rate will be $29.66 per hour. The application was approved on or before 9 March 2025. The employer can offer an overseas employee the role with the rate of pay at $27 per hour. INZ can approve the AEWV application, even though the rate of pay offered is below the minimum amount in the Job Check application, if it is satisfied the offered rate is a market rate.
CHANGE #3:
Maximum continuous stay
All AEWV holders will now be able to stay for either three or five years before having to spend 12 months outside of New Zealand.
EXAMPLE
If a migrant is applying for an Australian New Zealand Standard Classification of Occupations (ANZSCO) skill level 4 or 5 role, and their application was in progress on 10 March 2025, their visa will have a longer duration of three years if the application is approved.
All AEWV holders will now be able to stay for either three or five years before having to spend 12 months outside New Zealand.
CHANGE #4:
Minimum skills threshold
Applicants for an AEWV now only need to demonstrate two years of work experience or a Level 4 qualification. All AEWV applicants must show they have either:
A degree, or
At least two years of relevant experience, or
At least a relevant qualification that is at Level 4 on the New Zealand Qualifications and Credentials Framework (NZQCF). If an applicant holds an overseas qualification at this level, they will likely need an International Qualifications Assessment (IQA).
So, if an employer is looking to employ a migrant, they will only be able to hire migrants with at least two years’ experience, or a Level 4 qualification, or a degree.
Accreditation
obligations
Employers no longer need to complete the online employment law modules. Further, migrant employees no longer need to be given time to complete the employee version of the same modules. Employers must still provide migrant employees with settlement support information within one month of them starting work. This includes migrant employees moving from one type of temporary visa to an AEWV.
AEWV holders with dependent children
There has also been an increase in the income threshold for AEWV holders to support dependent children. Applicants for an AEWV must be earning a minimum level of income to be eligible to support their children for any dependent visas.
As of 10 March 2025, the income threshold increased to $55,844. This threshold will continue to be updated annually in line with changes to the median wage.
Interim visa work rights
Further changes come into effect in April 2025 regarding work rights for people on interim visas, while they are waiting on the outcome of an AEWV application. This includes:
Allowing AEWV applicants to have interim work rights if they apply while holding any type of work visa or from a student visa that permits work during term time; and
Enabling consideration of time spent on an interim visa that allows work when calculating a migrant’s total continuous stay under the AEWV, as well as for gaining work experience needed for work-to-residence pathways.
Will there be more changes?
We may see more tweaks to the AEWV scheme throughout the year, including when INZ moves away from the Australian New Zealand Standard Classification of Occupations (ANZSCO) to the National Occupations List.

I LOVE WHAT I DO
Awarded Most Valued Plumber (MVP) at the 2024 Plumbing World Young Plumber of the Year national final, qualified plumber and drainlayer Harmony Pearce wants to pave the way for other women considering entering the trades.
AUTHOR: JE T’AIME HAYR
Career starters
Switching from chef to plumber, Harmony Pearce is loving her new career at Dunedin-based Master Plumbers member company Adams Plumbing, Drainage, Electrical and Gasfitting.
Dissatisfied with her previous job as a chef, Harmony Pearce sought an industry that would keep her intellectually stimulated. As her brother is an electrician, she decided to add plumbing skills to the family. “I was 19 when I started looking for an apprenticeship,” says Harmony, who’s now 25. “I wanted a career I could grow in, and plumbing seemed perfect.” Trades, she discovered, offered a chance to keep learning and build a versatile future.
She is now a fully qualified plumber and drainlayer at Adams Plumbing, Drainage, Electrical, and Gasfitting – a company renowned for tackling major projects, such as the new McDonald’s franchise in Green Island. Harmony has become a valued part of their 61-strong team, which spans Dunedin, Cromwell and Queenstown.
Mark Preston, managing director and electrical manager at Adams, speaks highly
“I wanted a career I could grow in, and plumbing seemed perfect.”
of her impact since joining a year ago.
“Harmony knocked on our door looking for a job after completing her apprenticeship,” he says. “She’s a breath of fresh air – confident, personable, incredibly focused to get the job done, and her initiative is inspiring.”
Exceptional skillset
Harmony entered the 2024 Young Plumber of the Year competition as an apprentice, finishing second at her local branch level. She was picked as a wild card to advance to the Southern regional final and went on to secure a spot at the national final in Hamilton. Competing against nine other top contestants, Harmony found the experience both demanding and rewarding.
“We had to pipe and fit out a bathroom and install a hot water cylinder in just four hours – tasks I’d usually need more time for. But it was a fantastic challenge, and I now feel ready to tackle it again.”
Despite finding the time pressure tough going, Harmony stood out to the judges. “Harmony demonstrated positive attitude, integrity, and exceptional
skillset,” says Michelle Bingham, the event’s co-organiser. “We’ve witnessed her tremendous growth from the regional awards to the national final.”
Fantastic role model
Harmony hopes to pave the way for more young women considering entering the industry. “The trades open many doors,” she explains. “You can travel the world with a New Zealand plumbing qualification, and it’s something you can always fall back on. I love what I do, and I want others to see the potential in it too.”
Mark sees Harmony as a mentor in the making. “If we get another female apprentice, Harmony would be a fantastic role model,” he says. “She’s serious about her trade, seizes opportunities, and has a ‘get on and do it’ attitude. A lot of people could learn from her.”
Looking ahead, Harmony is focused on excelling in her trade and is working toward her gasfitting qualification as well as IQP and limited electrical certifications whilst also setting her sights on the Young Plumber of the Year title – a goal she’s determined to achieve.

Leak detectorist
“Here’s a goodie I found when re-doing a bathroom due to the shower leaking,” says Daniel Verschuur.
“Can you guess what the issue was?”
Hot water solution?!
“We were engaged to quote replacing a HWC on a customer’s house,” says Tim Yeoman of Whitehead Plumbing & Gas. “They ended up only ordering the HWC. We assumed someone else had done the install. Then we got a call a few weeks later to reposition the HWC we supplied.
“He had pulled down the wall between the HWC cupboard and laundry and wanted us to replace the old pressure PVC in the wall. I asked about him having no hot water for a couple weeks, he replied, ‘Oh, did I not tell you?’, and showed me this.
“Installed in a bathroom, fed from a garden hose, connected to a shower mixer on top of the shower. Complete with the CWE dripping onto a plastic container. His final remark was, ‘It is a little annoying only having hot water in one shower, not the kitchen.’
“Don’t worry, we booked him in to re-install at our next booking.”

Zane Britton of BOI Plumbing & Gas found this sorry set up. “Califont within source of ignition limits. Gully trap within bottle limits.”
