Our country’s steel industry is set to undergo a major transformation with the launch of New Zealand Steel’s new Electric Arc Furnace (EAF) in late 2025.
This project is more than an upgrade, it’s a decisive move towards sustainable steel production, ensuring Pacific Steel – and our steel industry as a whole – remain resilient and environmentally responsible for future generations.
This shift will reduce coal reliance by at least 50% and cut emissions by 45% from day one, contributing to a 1% reduction in New Zealand’s total annual emissions.
What does the future look like?
New Zealand Steel is replacing its current oxygen steelmaking furnace and two coalfuelled kilns with a state-of-the-art Electric
Arc Furnace (EAF). This transition marks a crucial step in New Zealand’s largest industrial decarbonisation effort. Using our largely renewable grid, the EAF will melt domestic scrap steel, which was previously exported, into prime steel for new products. This shift will reduce coal reliance by at least 50% and cut emissions by 45% from day one, contributing to a 1% reduction in New Zealand’s total annual emissions.
Locally made, low emissions steel reinforcing products
The EAF will be integrated into the existing steelmaking process and will allow a range of scrap levels to be used, significantly reducing emissions. Two primary steelmaking blends will be used.
The proposed standard blend consists of 50-60% scrap, with the remainder made up of iron, and has an estimated Global Warming Potential (GWP) of ~1.7 kgCO2eq*. This blend cuts emissions by over 50% for reinforcing steel, meeting the criteria for a 6-star Green Star building in terms of upfront carbon**.
The 100% scrap blend is a special mix that supports strong sustainability outcomes, with an estimated GWP of ~0.4-0.5 kgCO2-eq*. Whilst lower emissions steel reinforcing products exist internationally,
transport emissions become a significant contributor to the overall landed emissions and are accounted for in reputable wholeof-life LCA calculations.
*Indicative GWP based on early internal modelling. Full LCA & verification not complete.
**Reinforcing is only one component of an entire building, and when calculating upfront carbon emissions all components must be considered. The emissions reductions of our reinforcing can make a significant contribution, but not necessarily achieve it alone.
The future is circular Pacific Steel is committed to leading a local-made, low-carbon future. The EAF project is the perfect example of the circular economy model, where materials
are continuously reused and recycled, maximising their lifecycle and value. Recycling domestic scrap steel means a reduced carbon footprint and reliance on imported materials, as well as an increase in New Zealand’s self-sufficiency.
To find out more about the EAF project and Pacific Steel’s commitment to the circular economy, visit pacificsteel.co.nz/ sustainability/eaf
We’re proud to announce that we’re set to have our source steel supplied from New Zealand Steel’s new Electric Arc Furnace (EAF) from 2026. Support us while we transition by investing in locallymade products that will contribute to ensuring steel production in New Zealand is sustainable for generations to come. Recycling domestic scrap steel instead of exporting it offshore means we’ll be maximising the lifecycle of our products and delivering locally made, lower carbon reinforcing steel. The introduction of the EAF at New Zealand Steel and your support of locally-made, means you’ll be part of the biggest industrial decarbonisation effort in our country’s history to date. Around 50% less coal usage and 45% less emissions (scope 1 & 2) from day one is just the beginning of a significant industry transformation. Join us on this landmark journey.

New figures have shown the annual number of homes consented to – new residential building projects embarked on – is again down compared to the year prior.
Stats NZ says that in the year ending January 2025, 33,812 new homes were consented to, down 7.2% compared with the year ending January 2024.
The annual value of non-residential building work consented was $8.9 billion, down 9.7% from the year ended January 2024.
11% more new homes were consented to in the month of January 2025 compared to January 2024, but economic indicators spokesperson Michael Heslop says figures still remain below the levels seen in January 2022 and 2023.
Of the 2,203 new homes consented, there were 1,077 stand-alone houses consented, up 20% compared with January 2024, and 1,126 multi-unit homes consented, up 3.1%.
These findings from Stats NZ paint an especially grim picture when paired with QV CostBuilder’s latest study, which found building costs have increased at an average rate of 44% over the last four years despite the rate of inflation slowing markedly last year.
The study compared the cost of building a standardised 150m² home across six main urban centres – Auckland, Wellington, Christchurch, Dunedin, Hamilton and Palmerston North.
“Despite always being the most expensive city to build a home in overall, construction costs actually increased by the smallest margin in Auckland (39.4%). Christchurch (40.5%) wasn’t far behind, with Hamilton (44.8%) sitting just above average,” QV reported.
“In real dollar terms, however, Wellington saw the largest average increase in the cost to build a home; its average build cost increased by $900 per square metre in four years. As a percentage, the cost of building a home in the capital increased by an average of 45.9% since 2020.
“But the good news for developers or for anyone looking at building a home is that the rate of building cost inflation has slowed markedly in recent years.
“The smallest percentage increases last year were in Auckland (0.7%) and Hamilton (0.7%). Palmerston North (2.2%) saw the largest increase in 2024.”
“There are currently no significant differences in the rate of construction cost increases across the country. What these numbers show is just a relatively small difference in cost, which can be
attributed to variable labour rates, different company overheads, some variance in materials, and differing transport costs across the country,” quantity surveyor Martin Bisset says.
“After years of pronounced inflation that came as a result of managing the COVID-19 epidemic here and abroad, it’s good to see that construction costs have become significantly more stable in recent years. Hopefully, the years of such staggeringly
large construction cost increases are now firmly in the rear-view mirror.”
Ongoing geopolitical instability in Ukraine and the Middle East, the proliferation of US-led trade wars, and increased tariffs on construction materials also impact the cost of building homes in New Zealand, he adds. “Given that Aotearoa relies so heavily on importing building materials, a lot always depends on the buying power of the New Zealand dollar.”
Figures from Statistics New Zealand have revealed the total floor area of consented new homes was just over 4.7 million square metres, which marks a 7.2% decrease compared to the year ended January 2024. It’s the lowest for a January year since 2015, says Stats NZ economic indicators spokesperson Michael Heslop.
New Zealand homes have been shrinking for a while now. In February 2023, Stats NZ reported the median floor area of new homes had decreased by 10%; in 2022, it was 126 square metres, and in 2021, it was 140 square metres.
Michael Heslop says it’s due to an increase in the number of multi-unit homes consented to. Apartments, townhouses, flats, and retirement village units tend to be smaller than stand-alone homes.
But stand-alone homes are getting smaller, too. “Ten years ago, more homes were being consented with a floor area above 200 square metres than below. This has shifted in recent years, with more homes being consented with a floor area below 200 square metres,” he said in 2023.
Average floor areas are influenced by garages in houses and townhouses and shared spaces
in apartment buildings, such as corridors and basement car parking.
Denser cities and neighbourhoods, so homes with smaller floor areas, are New Zealand’s response to the housing crisis. Smaller homes and more multi-unit developments make sense as demand increases, yet these sacrifices generally haven’t translated to more affordable housing.
Take the Auckland Unitary Plan, implemented in 2016. Though it facilitated the construction of approximately 22,000 additional homes between 2016 and 2021, leading to a 50% increase in consents, housing affordability challenges persist.
In 2019, the annual Demographia International Housing Affordability study deemed all major housing markets in New Zealand “severely unaffordable,” with median house prices exceeding six times the median annual household income.
High-density housing does lead to lower house prices, reduced traffic, and lower infrastructure costs in the long run. It also creates better job markets, fosters innovation, and allows businesses to specialise. Studies suggest increasing housing density in cities like Auckland could significantly boost productivity and wages.
Still, New Zealand’s current housing policies force people into less productive areas,
which lowers our GDP and living standards. Minimum lot sizes, height restrictions, and limits on apartment construction reduce housing supply, therebydriving up prices and pushing people to less productive regions. Infrastructure funding that prioritises sprawl over urban intensification also contributes to the problem.
House prices are forecast to rise modestly this year and next, following a decline in 2024, per a Reuters poll of housing experts. They cite lower interest rates as the key driver. The Reserve Bank of New Zealand has cut interest rates to support house price recovery, which fell nearly 20% from a late 2021 peak.
That decline is only about half of a more than 40% surge during the pandemic, pricing many first-time home buyers out of the market. “We see a bit more potential upside in the market this year given mortgage rates are falling faster and probably by more than we had been anticipating three to six months ago, but not by a great deal,” said Infometrics’ chief forecaster Gareth Kiernan.
“Given that housing still looks relatively unaffordable, we expect that through the course of this year, interest rates will still be a reasonably important driver.”
Without broader policy changes to increase supply and improve affordability, the housing crisis will likely persist despite the shift to smaller, denser homes. While lower interest rates may provide some relief, they alone cannot address the structural issues driving high housing costs.
No disruption for trainees and apprentices. That’s the key message for those in New Zealand’s infrastructure industry from the sector’s leading training provider as the country’s vocational and educational training (VET) structure is reviewed by the Government.
Connexis supplies industry training to infrastructure companies across the country, including civil construction, energy, water and telecommunications sectors.
Connexis Executive Director Kaarin Gaukrodger says at the time of writing, the Government was still assessing submissions on the best future structure for vocational training, but trainees, apprentices and employers can be reassured that learners will not see any interruption or changes to their current training.
In December last year the Government announced it was seeking further targeted consultation on the future delivery of VET as part of the disestablishment of Te Pūkenga. That consultation closed on 21 February 2025.
“As we wait for the outcome of that consultation, all apprenticeships and training programmes continue as normal and at Connexis we continue in ‘business as usual’ mode, working hard with industry to ensure training programmes meet the needs of both employers and trainees,” she says.
New Temporary Traffic Management (TTM) micro-credentials are key new programmes being launched by Connexis, the first training organisation to offer the qualifications in New Zealand.
TTM is a core skill requirement affecting almost any infrastructure project, particularly maintaining and constructing key roading network assets, Gaukrodger says.
“We are extremely excited to be a part of delivering the new risk-based TTM microcredentials, as TTM plays such a big role in the successful roll out of infrastructure projects.
“As well as ensuring consistency in the approach to TTM, these micro-credentials offer formal recognition of skills for those who complete them, and could help form the foundation of a career built on traffic management safety,” she says.
Two micro-credentials were released late last year - Temporary Traffic Management Risk Assessment (Level 4, 15 credits) and Temporary Traffic Management Design (Level 4, 20 credits) with further micro-credentials to be rolled out in the coming months.
These micro-credentials have all been developed to meet a new risk-based
approach to TTM as outlined in the NZTA Waka Kotahi New Zealand Guide to Temporary Traffic Management (NZGTTM).
For employers it’s a great way to build connections with potential future apprentices and try them out in a realworld environment. It gives students a much more accurate and deta idea of what a career in these industries looks like so they can make informed decisions about their future.
Ongoing promotion of the infrastructure industry is critical to attract the next generation of workers. Showcasing the advantages and opportunities of a career in infrastructure and providing opportunities for school students to engage with the industry remains a key part of Connexis’ focus through 2025, with a push for programmes like Gateway and events like Girls with Hi-Vis®.
“Anytime we are able to help young people experience what careers in the infrastructure sectors offer, rather than just tell them, is just that much more memorable and powerful for them.”
Gateway Connexis Gateway programmes combine on-job experience, theory and assessment with micro-credentials such as Introduction to Civil Infrastructure Works Level 2 or 3, allowing students to build their on-job skills and knowledge while still at school and gaining NCEA credits.
“For employers it’s a great way to build connections with potential future apprentices and try them out in a realworld environment. It gives students a much more accurate and detailed idea of what a career in these industries looks like so they can make informed decisions about their future, while connecting them with a local employer,” Gaukrodger says.
Girls with Hi-Vis®
Registrations are also open now for schools wanting to participate in Connexis Girls with Hi-Vis 2025® (GWHV) events, which will run throughout June.
GWHV gives female high school students the opportunity to gain hands-on experience with employers either in their yards or onsite at some of the country’s key infrastructure projects and assets. While there, students are able to talk to inspirational women already working in the industry and learn what a career in the infrastructure industries can offer.
“Not only does GWHV showcase the skills and career paths open to women in industries such as civil, it opens the students’ eyes to some of the huge and vital projects they could be working on that serve their own community - while introducing them to the employers who have those opportunities.”

The New Zealand Certified Builders Apprentice Challenge is back for 2025 with BCITO coming on board as the new major sponsor.
The Apprentice Challenge celebrates up-andcoming leaders in the construction sector and puts their carpentry skills to the test.
Apprentices build a project over six hours in a battle for first place in their region, achieving bragging rights and a chance to win $10,000 in prizes at the national competition.
Apprentices compete at regional heats around New Zealand on 12 April, with the winners going through to the national final, which is held at the NZCB Conference in Hamilton on 6-7 June.
BCITO is New Zealand’s leading building and construction apprenticeship provider and BCITO director Greg Durkin says the organisation is proud to be the major sponsor of the Apprentice Challenge.
“The NZCB Apprentice Challenge highlights the exceptional skills and dedication of apprentices in the building industry. BCITO also acknowledges the professionalism and
dedication of employers and senior trade staff who train these talented apprentices.
“The Apprentice Challenge is a fantastic opportunity to showcase the talent of the apprentices, celebrate their hard work, and inspire the next generation of tradespeople to pursue excellence in their craft.”
The NZCB Apprentice Challenge is now in its fifteenth year and has become one of the biggest events on the construction industry calendar.
“The Apprentice Challenge is a major part of how we grow the next generation of builders, getting them off to the best start possible in the industry,” says NZCB Chief Executive Malcolm Fleming.
“The competition is well-recognised on the CVs of young builders. Many NZCB builders are alumni of the Apprentice Challenge themselves and now encourage their own apprentices to give it a go. We’re even seeing past winners come back as judges and technical advisers.
“We’re thrilled to welcome BCITO as the main sponsor for the Apprentice Challenge. Over several decades, NZCB builders have established a deep trust with BCITO to help progress the careers of their apprentices. It’s the perfect fit with this event.”
Entries for the NZCB Apprentice Challenge open on 1 February 2025 and close on 20 March 2025.
Entry is open to all apprentices in New Zealand of any age and in any stage of their apprenticeship and is free for NZCB and BCITO-aligned apprentices.

For over 17 years, Firestop Centre has been a key partner for specifiers and installers in New Zealand’s passive fire protection market.
Greg Hand, Director of Firestop Centre, shares insights into the company’s role and what drives its success.
“Our mission in New Zealand’s passive fire protection industry is clear: we provide firestopping solutions with full transparency in compliance and technical support,” says Greg. “Clients can access all necessary documentation, including test reports, on our website at any time. And if they have questions, our technical team is always available to provide clarification.”
It's about creating real value while supporting the New Zealand market with straightforward fire-tested products and systems, he adds.
“Besides, we simplify the specification process and provide clear installation instructions for all fire-rated systems conveniently arranged in the Firestop Centre System Selector.”
Greg says he is proud of the Firestop Centre System Selector, an online database that organises all fire-rated systems. "Currently, we have over 400 fully compliant fire-rated systems that can be specified and installed in construction projects across New Zealand.”
Recently, Firestop Centre decided to go beyond distribution by launching its own brand, Firestop. "We've learned a lot over the years and have seen the industry's needs and the challenges installers face on-site. So, we thought, if not now, then when? We invested much time and money to research, design, and test Firestop firerated systems here in New Zealand. It was fun and now we can see the results.
"Did you know that before Firestop duct wrap 38, the New Zealand construction industry lacked a tested duct wrap solution for circular duct protection? Now it has one.
“We recently signed a distribution agreement with Agnitek, a new Australian fire-stopping brand,” Greg shared. “Their testing is conducted locally, just a fifteenminute drive from our warehouse, making it easy for the team to observe the AGNI fire performance firsthand. With their
extensive testing program and strong compliance record, AGNI-Systems and AGNIProducts are a fantastic addition to our firerated range.”
Greg highlighted ALLPROOF, a wellrecognized local passive fire protection brand in Firestop Centre’s distribution lineup. “Working with ALLPROOF products is always a pleasure. They are local, popular, fully compliant, and fit for any project. Plus, their sales performance never disappoints.”
Greg also mentioned that with the industry trend of preferring locally tested solutions, the Firestop Centre team can’t
underestimate the significance of locally tested fire-rated systems.
“So, the current challenge for us is to maximise the exposure of locally tested solutions and help make specifiers' and installers' lives easier.”
Greg kept talking about all “coming soon” fire-rated systems, which the Firestop Centre team specifically requested manufacturers to test locally in a thirdparty IANZ-accredited testing laboratory. These are solutions for Hebel and Shaftwall, plumbing, HVAC and electrical fire stopping.
The New Zealand cement and concrete industry, represented by Concrete NZ, is now five years into its decarbonisation journey, aligning with the Global Cement and Concrete Association’s (GCCA) Cement and Concrete Industry Roadmap for Net Zero Concrete. With 2020 as the reference year, our industry has been actively reducing emissions and making tangible progress towards our 2030 and 2050 targets.
As Concrete NZ’s Sustainability and Policy Director, I have had the privilege of helping to facilitate this transition, and the progress we’ve made is a testament to the industry’s commitment to reducing its carbon footprint and ensuring a resilient built environment.
The 2050 Roadmap
The concrete industry plays a critical role in New Zealand’s built environment, and we are determined to significantly reduce greenhouse gas emissions to help the country meet its international climate obligations. Our Roadmap outlines the pathway to achieving this, targeting all key players in the concrete value chain, from cement manufacturers to designers, specifiers, and contractors.
By 2030, we aim to cut direct and electricityrelated emissions (Scope 1 and 2) by 44% from 2020 levels, equating to around 400,000 tons of CO2 reductions annually. By 2050, the industry seeks to achieve netzero carbon concrete, and potentially even negative emissions.
The seven key strategies - or levers - that guide our decarbonisation efforts include:
1. Reducing clinker production emissions – i.e., use of waste materials as alternative fuels to replace fossil fuels in cement production.
2. Increasing use of Supplementary Cementitious Materials (SCMs) – i.e., using less cement through partial
replacement with SCMs (e.g., fly ash, slag and natural pozzolans) and mineral additions.
3. Enhancing efficiency in concrete production – i.e., through modern centralised concrete batching plants, advancements in concrete technology and mix design.
4. Improving design and construction methodologies – i.e., demand-side measures, such as lightweight structural members.
5. Reducing emissions from electricity use.
6. Accounting for natural carbon uptake via recarbonation – quantify concrete’s capacity to absorb atmospheric CO2.
7. Deploying Carbon Capture, Utilisation, and Storage (CCUS) technologies in cement manufacturing.
In the past five years, we’ve seen significant developments, particularly in the availability and use of SCMs such as granulated and ground blast furnace slag
(GGBS) and fly ash. These materials replace a portion of traditional Portland cement, effectively lowering the carbon footprint of concrete and aligning with our sustainability goals.
Sustainability reporting and industry progress
Concrete NZ recently released its second Sustainability Report, building on the 2021-2022 baseline. This report not only tracks progress against our 2050 Roadmap but also provides a broader view of the industry’s sustainability efforts, health and safety metrics, as well as the United Nations’ Sustainable Development Goals (SDGs).
Key findings from the 2023 Sustainability Report
• Direct and electricity-related emissions decreased by 6% from the 2020 baseline
• SCM replacement of Portland cement increased significantly nationwide from the 2021/22 report
• 56% of local cement production now utilises alternative fuels
• All cement suppliers have actively developed lower-clinker cement formulations.
Expanding the dataset was a major priority this year, with reporting now covering 78% of the ready mixed concrete market by volume and including reinforcement processors
for the first time. This broader industry participation reflects a growing recognition of sustainability’s importance and the collective commitment to transparency.
Sustainability reporting enables companies to track improvements over time and refine their sustainability strategies. Concrete NZ will continue to publish these annual reports to measure progress, identify gaps, and highlight emerging opportunities.
To accelerate Roadmap implementation, Concrete NZ has launched the Transformation Project, a multi-year initiative supported by funding from the BRANZ Building Research Levy and the Ministry of Business, Innovation and Employment’s (MBIE) Building Innovation Partnership.
The Transformation Project aims to:
• Define and standardise the specification of low-carbon concrete to ensure performance consistency across regions.
• Investigate necessary updates to concrete standards to support greater SCM uptake.
• Assess international best practices and apply learnings to the New Zealand context.
• Identify quick-win design and construction strategies for using low-carbon concrete.
• Evaluate the real-world carbon savings from projects that specify low-carbon concrete.
With funding secured and expert working groups engaged, the Transformation Project is now advancing practical solutions that will enable the industry’s transition to net-zero concrete.
Government relations Advocating for a Low-Carbon Future
Concrete NZ is actively engaged with government agencies to ensure that regulatory settings and public procurement policies support the use of sustainable building materials. Our recent discussions with the Ministry for the Environment and MBIE have focused on:
• Ensuring a level playing field for all building materials in sustainability regulations
• Developing “green lead markets” that incentivise the use of low-carbon concrete
• Establishing stable, long-term policy frameworks to drive investment in decarbonisation
• Supporting CCUS regulatory frameworks as part of New Zealand’s broader climate strategy.
Additionally, we are working to align our industry’s sustainability efforts with the government’s infrastructure priorities. Durable, low-maintenance concrete is well suited to long-term infrastructure projects, making it a natural fit for Public-Private Partnerships (PPPs) that seek to maximise lifecycle value.
Despite our progress, several challenges remain. One of the key barriers to widespread adoption of low-carbon concrete is the perception of a “green premium” – the idea that sustainable alternatives are significantly more expensive. However, in many cases, costs are comparable, and we are working to
dispel this misconception through education and awareness campaigns.
Other yet untapped opportunities include:
• Scaling up SCM uptake to turn higher utilisation ratios into relative cost reductions
• Refining performance-based specifications to ensure the best use of low-carbon concrete
• Encouraging early supplier engagement to optimise concrete mix designs for emissions reductions
• Advocating for policy incentives that support low-carbon concrete in government projects.
Concrete NZ is making environmental data more accessible, helping members meet growing sustainability requirements. Type III Environmental Product Declarations (EPDs) provide transparent, third-party verified data on a product’s environmental impact, including CO₂ emissions, energy use, and resource consumption.
While essential for green building certifications, EPD certification can be costly and time-consuming - particularly for rapidly evolving low-carbon concrete innovations. To address this, Concrete NZ invites members to use the Global Cement

There’s a lot of grey matter around the subject of who is actually competent. So much so, no one knows whether the use of the word is for self-gain and glory or to tick a box. Furthermore, who makes the decision? Even greyer (is that even a word), a Person Conducting a Business or Undertaking (PCBU) holds all the risk and accountability on this.
The Health and Safety at Work Act 2015, section 36, 2 says: “A PCBU must ensure, so far as is reasonably practicable, that the health and safety of other persons is not put at risk from work carried out as part of the conduct of the business or undertaking.”
The PCBU has to make the call so that they meet their obligations on this above mentioned section of the Act. The act itself does not detail a competent person or who determines it as they leave it to the PCBU, who must determine competency. How can a PCBU determine competence when they might not know enough on the
matter themselves? That’s where guidance comes in. It provides the support for a PCBU on how to gather the evidence so they can determine a competent person.
The PCBU has a duty to record this information so that it can be referred to at a later date.
That’s where training comes in – it provides the support and evidence that a person is competent and the achievement of the performance criteria of the course is the record.
Recently the Elevating Work Platform Association of NZ (EWPA) released guidance on exactly this subject when referring to Mobile Elevating Work Platforms (MEWPs).
A competent person is a person who has acquired, through education, training, qualification or experience or a combination of these, enabling that person to perform the task required.
When selecting personnel to operate, supervise, maintain, inspect, perform rescues, and transport MEWPs, it is essential to ensure they are appropriately trained, qualified, and experienced for their specific roles to maintain safety, compliance, and operational efficiency.

Wireless infrastructure presents a powerful opportunity for construction companies, offering enhanced connectivity, scalability, cost savings and remote monitoring.
These are all crucial elements that contractors need to succeed and remain competitive in today’s thriving construction industry.
Of course, digital solutions come with a degree of risk, and there are pertinent steps contractors can take to mitigate that risk and reap the rewards.
Here, we take a deeper dive into the benefits, risks and solutions of wireless infrastructure for New Zealand contractors.
Connectivity enhancements
Wireless infrastructure can provide enhanced connectivity across construction sites. By establishing a robust wireless network, NZ contracting teams can seamlessly communicate, share data and enjoy real-time access to critical project information. Team collaboration leads to improved coordination, quicker decision-making and more efficient project execution.
Scalability
Wireless solutions are scalable, making them ideal for construction projects with evolving requirements. For example, if a contractor plans on expanding the project scope, adding new equipment or including additional users, wireless technology can quickly scale to meet these demands. This scalability future-proofs the infrastructure, minimises disruptions and reduces the need for expensive upgrades or modifications.
Cost reduction
Wireless infrastructure deployment can bring notable cost savings to your projects. Eliminating the extensive cabling required in traditional setups reduces installation costs and labour expenses. As a bonus, wireless networks typically require less maintenance than traditional solutions. These cost efficiencies contribute to overall project budget optimisation, allowing contractors to leverage resources strategically across each project phase.
Remote monitoring
Wireless technology allows for remote monitoring, enabling construction teams to oversee project activities and assets from anywhere at any time – an option not offered by traditional solutions. Remotely monitor
equipment performance, track inventory levels, and monitor environmental conditions through IoT (Internet of Things) devices and sensors integrated into the wireless network. Potential risks and issues are promptly identified so contractors can prevent or resolve them in a safe and timely manner.
Security and reliability of wireless infrastructures
Wireless infrastructure also presents unique challenges for construction professionals working on-site. If not adequately secured, wireless infrastructure can be vulnerable to cyber threats. Construction is one of the most heavily targeted industries for cyberattacks, and the average cost of a data breach in Australia has grown by 32% over the past five years, up to A$4.03 million, according to a 2023 IBM report.
Risk mitigation strategies
To mitigate the security risks associated with wireless infrastructure, robust security measures are essential:
• Encryption: Utilise strong encryption protocols, such as WPA3 for Wi-Fi networks, to secure data transmissions and prevent unauthorised access
• Access control: Implement strict access policies to ensure that only authorised personnel and devices can connect to your infrastructure
• Network segmentation: Segment the wireless infrastructure into different zones or Virtual Local Area Networks (VLANs) to isolate sensitive data and limit potential security breaches
• Regular audits and updates: Conduct regular security audits to identify vulnerabilities and ensure compliance with industry regulations
• Employee training: Provide cybersecurity training to employees, contractors, and stakeholders to raise awareness of best practices for maintaining a secure wireless environment.
Wireless infrastructure can also come with unique reliability challenges, particularly around network stability. Factors such as signal interference, environmental conditions, distance limitations, and equipment malfunctions can all impact network performance and reliability.
Any downtime or connectivity issues can disrupt your workflows and timelines, leading to productivity losses. To enhance the reliability of your wireless infrastructure, consider leveraging advanced solutions and technologies:
Wireless solutions are scalable, making them ideal for construction projects with evolving requirements. For example, if a contractor plans on expanding the project scope, adding new equipment or including additional users, wireless technology can quickly scale to meet these demands.
• Redundancy and failover mechanisms: Incorporate mechanisms within your network to provide backup pathways and automatic switchover in case of network failures or disruptions
• Load balancing: Utilise load balancing techniques to evenly distribute network traffic across multiple access points and channels, preventing congestion and optimising overall network performance
• Performance monitoring and management tools: Implement robust performance monitoring and management tools that provide real-time visibility into network health, identify potential bottlenecks or issues, and enable proactive troubleshooting and optimisation.
Implementation best practices
Successful implementation of wireless infrastructure requires careful planning and strategic design. Identify project requirements and set key performance indicators (KPIs) for the infrastructure.
Conduct site surveys to assess environmental factors, potential sources of interference, and optimal placement of access points and devices. Collaborate with network architects, engineers, and IT professionals to create a robust, scalable wireless network to meet your construction site’s specific needs.
Additionally, contractors should wisely invest in training and education programs for both internal staff and external contractors. All users should be trained on the infrastructure, network security protocols, best practices for connectivity and device management. Empower personnel with the knowledge and skills to effectively operate, maintain and secure the wireless infrastructure.
A power tool for contractors
Wireless infrastructure presents a powerful opportunity for contractors, and to wisely capitalise on these advantages, construction professionals must address security concerns, ensure network reliability, and follow best practices during implementation. Then, reap the productivity and efficiency rewards.

The construction industry can be tough, even when the economy is strong. When the economy turns sour, risk mitigation strategies are vital.
Times are still tough
Global economic activity is expected to remain subdued in the near term according to the Reserve Bank’s February 2025 Monetary Policy Statement. Activity remains below trend, and “[t]his reflects falling activity in interest rate sensitive sectors such as construction”. Growth is expected to recover during 2025, but the speed of that recovery is uncertain.
Construction sector leads credit defaults, and insolvencies are high
Inflation and interest rates have been a constraint for construction clients. With slow and uncertain work pipelines, aggressive pricing can lead to tighter profit margins and cashflow concerns. This puts a strain on businesses.
Credit defaults have hit the construction sector particularly hard, with construction defaults up 35% year-on-year, the largest increase of any sector (February 2024, Credit
There are now strict accounting practices (including reporting) for holding retentions. Non-compliance can lead to large fines and personal responsibility for directors.
Indicator issued by Centrix). Company liquidations across all sectors are up 38% compared to the previous period. Centrix reports, “Notably, in January, 24% of these insolvencies were attributed to the construction sector”.
In this environment, contractors need to be alive to their risks. Proactively managing such risks can preserve cash flow and protect contractors in conditions where issues and disputes are more common.
Contracts that work for you
Getting the contracts right saves a lot of trouble:
• Know who you’re dealing with: Does the client have enough contingency? How financially healthy and reliable is the supply chain?
• Allocate the risks: Are the risks allocated to the person who can control each risk? Can that person afford those risks?
• Align the contracts: Do the subcontracts align with the client contract? If not, the gaps can leave a contractor exposed.
• Align the pricing: A fixed price client contract and uncertain subcontractor/ supplier pricing can lead to losses.
• Write up the contract: Even if the building work costs less than the $30,000 mandatory threshold for residential building work, have a written contract. This is vital for disputes relating to payment or scope.
Keep on top of admin and payment claims
Cash flow is the key to solvency. Good admin and getting payment claims right preserves cash flow and prevents expensive and timeconsuming disputes.
• Payment claims to the client: If payment claims / invoices are set out in the format required by the Construction Contracts Act 2002 (the Act), contractors can get the benefit of the ‘pay now argue later’ concept which is useful when dealing with difficult clients.
• Payment schedules to subcontractors: Such enforceability under the Act also works for subcontractors against contractors. It’s important that contractors issue valid payment schedules. Otherwise, it will be the contractor who has to ‘pay now and argue later’.
An experienced quantity surveyor or project manager can prepare these documents and help contractors improve their cash flow and avoid expensive disputes.
Contractors should check their retention money is being held properly by clients. In turn, contractors need to ensure they’re looking after their subcontractor’s retention money to avoid personal exposure to fines and losses.
Know your rights and responsibilities on retentions
There are many examples of clients and head contractors who went insolvent, and the retentions disappeared with them. However, the Construction Contracts (Retention Money) Amendments Act 2023 improved the protections for contractors and subcontractors.
There are now strict accounting practices (including reporting) for holding retentions. Non-compliance can lead to large fines and personal responsibility for directors.
Contractors should check their retention money is being held properly by clients. In turn, contractors need to ensure they’re looking after their subcontractor’s retention money to avoid personal exposure to fines and losses.
Know when to notify issues and raise disputes
Some contracts have strict notification requirements requiring contractors to raise any variations or issues in writing within a certain number of days or else lose the right to do so.
If an issue is raised but not resolved, contractors have access to adjudication
under the Act, which is unique to the construction sector and provides a quick and cost-effective third-party decision without needing to go to court. Used right, this is a powerful tool that can secure cash flow when there are disputes.
It’s easier than it sounds
Many of these steps are about good habits, templates and processes. Spending a bit of

Primarily known as a picturesque holiday destination for people all over the country and the globe, Queenstown is rapidly growing into one of New Zealand’s most sought-after places to live. With its breathtaking views, booming tourism industry, and growing reputation as a lifestyle hub, a growing number of people are choosing to make Queenstown their home.
The consistent surge in popularity is driving significant growth, sparking questions about whether Queenstown could one day outpace Dunedin – not just in population, but also in influence, infrastructure, and economic pull. As the district plans for its estimated growth, the future of Queenstown has become a topic of discussion.
Over the last ten years, the QueenstownLakes District has grown at a rate of 5.6% per annum, which Queenstown Lakes District mayor Glyn Lewers says makes it one of the fastest-growing areas in the country.
“Those numbers themselves just tell a story of a very fast-growing district, and from what we see, it doesn’t seem to be easing off.”
What Lewers says is bringing people to make Queenstown their permanent home is not just the landscapes, but also the connections through Queenstown Airport.
“It’s a great place to live, and the environment is stunning, plus we have international connections through our airport. So with the direct flights from Auckland to here, we’ve also got direct flights from Melbourne and Sydney, so the eyes that are upon us are a lot greater than other areas in New Zealand.”
When much of the country saw a decrease in growth, Queenstown-Lakes District was one of the few that still had growth during
It’s got year-round attractiveness, but believe it or not, summer is the busiest period. You’d think winter with the ski fields, but no, actually summer is great here.
COVID-19, and Lewers adds it has just gone up again after COVID-19 as well, which he also credits to the year-round attractiveness of the region.
“It’s got year-round attractiveness, but believe it or not, summer is the busiest period. You’d think winter with the ski fields, but no, actually summer is great here.”
According to the Queenstown Lakes District Council, the latest projections indicate a medium scenario in which their residential population is expected to increase to around 100,000 by 2053. Because of this, Lewers says that they have had to invest quite significantly in the growth.
“If you look at our next ten-year plan, I think it’s 700 million dollars set aside just for
growth, and a further 470 million for tourismrelated infrastructure as well, so it is a big ask for a population base of only 52,000."
Due to Queenstown’s specific landscape, building for growth could be exceptionally hard, as “given the nature of Queenstown with its alpine environment, flat developer land is our premium and serving that land is more expensive as well because we’ve got some decent rivers to cross.
“The entire infrastructure-rated network is quite stretched out due to the nature of the mountains, which makes building a network and achieving network resilience quite challenging, and it also incurs a slight increase in costs.”
Lewers adds that a significant concern for the Council with the estimated growth is that it is occurring faster than predicted in their high-growth scenario. “We have to seriously have a re-look at our investment structure and how we are going to deal with that. And,
if that does occur within our debt limits, again rates would have to rise, and this is the whole question of growth not paying for growth in that sense. So that’s probably the main issue. If it grows any faster, base infrastructure, like energy and electricity, would come under serious strain.”
Lewers also says that roading and schooling, both secondary and primary, which are already under strain, would become more excessive. “The price of doing those sorts of things has only gone one way and it’s up in the last couple of years,” he adds.
“The whole issue of growth, I can say, probably consumes my mind 80% of the time, both being strategic about it, how we set ourselves up for the future better, and actually looking at doing things differently.”
The Queenstown Lakes District Council has developed a 30-year infrastructure strategy (2024-2054) to address this, outlining how
Queenstown, along with Wanaka and Cromwell, are looking to probably be the second largest population base in the South Island.
and where the area is expected to grow. The strategy aims to address the challenges of rapid growth by planning and investing in infrastructure that supports sustainable development, as well as enhancing community wellbeing.
Regarding Queenstown being viewed as a major centre in the South Island, Lewers believes it already is.
“I think anything that happens in Queenstown seems to make national news, whereas if it were somewhere else, it probably wouldn’t even make the local paper.
“Queenstown, along with Wanaka and Cromwell, are looking to probably be the second largest population base in the South Island.
But he says that he doesn’t think Queenstown itself will be bigger than Dunedin “but the district will be, so that includes Wanaka and outlying communities, you just look at the virtues of where we are going, given our international links, our importance to New Zealand, yeah it’s got a lot going for them.”

After discovering 3D printing technology around three years ago, the team at Iconic Construction quickly became intrigued. They approached QOROX before starting a new childcare facility in Hamilton, and after seeing the benefits of 3D printed concrete during a visit to the QOROX showroom, decided to update and reconsent a project in order to give it a try themselves.
“From that initial meeting, I guess we fell in love with it. We thought it was really cool and were so impressed with what could be designed, and knew straight away how innovative it was and how we could use it building in New Zealand,” says Johnny Gordon, General Manager at Iconic Construction.
The recently completed 3D printed home in Brymer Heights, Rotokauri, took 99 days to complete and was designed by Waikato-based architects, The Architecture People. The home features include an open-plan living area, curved walls, three bedrooms, two bathrooms, and one and a half garage spaces.
Johnny says that all of the 36 walls of the home were printed off-site in the QOROX factory, which took a total of 24 hours of printing time over ten days to complete, and were then brought onto the site.
“One of the key benefits is around the time it takes to build a house. With this build, we started on the 23rd of July, and we had a Code of Compliance, which means you have Council sign off on the build, and this was issued on the 12th of December, so it took us four and a half months to build the house.”
Because this was Iconic Construction's first architecturally designed house using 3D printing, there was a lot of learning going on for the whole team. We still think that was really fast. We’re aiming to improve this with the ultimate goal of getting the build schedule down to around three months to build a 170 square metre house.”
One challenge that stood out to Johnny was the foam that goes inside the walls and serves as insulation, which he says was overfilled. “There was quite a bit of excess foam that required removing when the panels were placed on site. We’ve reviewed this and come up with an improved system for how the walls will be insulated in the
factory moving forward, so this doesn’t happen again.
“There has been a ton of learning for all involved on this build, and it’s a matter of taking those learnings, so we keep learning and developing an efficient system.”
The 3D home is predominantly constructed of concrete, featuring concrete floors and walls, and also has a traditional timber trussed roof system. Johnny says that, due to the floors and walls, the longevity of the home surpasses that of the standard New Zealand home. “You may need to replace windows, kitchen, and roofing, but you need to do that with any house. The longevity of the house is going to be multigenerational for families to be able to live in for hundreds of years rather than only a few generations before the house is demolished.
“That’s a really neat thing that happens in Europe a lot, they’ve got three, four-hundredyear-old houses that are concrete and stone, and the same with Asia, but here in New Zealand we don’t really have that. We build timber framed houses that only have a certain lifespan which is relatively short.”
While completing this build, there was significantly less waste than would be generated when completing a standard build, Johnny said. “With a build of this size, which is 167 square metres, you usually have up to three skips of waste; we only had one skip of waste, and then we had a lot of stuff that we took to recycling.” QOROX also 3D printed a curved seat that was placed in the garden. Rather than sending the excess foam from the walls to landfill, Johnny says they used some of it to put the 3D concrete printed seat in place.
Since opening the home to the public, the team have had about 700 people through so far, with some events coming up in the calendar. Johnny says the response has been overwhelmingly positive, and that “people
have come in and said it’s way better than they thought. They are really impressed by it and love the curves in the walls.” Johnny adds that there has been a small percentage that haven’t liked the 3D printed line look on the walls, “although you’ve got the option of plastering the walls if you want to, which is an additional cost though.
“We have been really happy with the public’s response, and the challenge for me is to be able to convert that from people liking it to wanting to build out of it.”
Iconic Construction has become a regional partner with QOROX, the company that brought the technology to New Zealand in 2020, and is excited to introduce 3D printing to the construction industry. Johnny says that they have also brought another robot, which is located in Christchurch, as they want to be able to build 3D printed houses in the South Island as well.
“We are early adopters of this technology, and we are excited to bring it to the market in New Zealand with QOROX.”

In the wake of damaging weather events nationwide, New Zealand’s natural hazards insurer is urging homeowners to understand the natural hazards that could impact their properties and their insurance limits.
Natural Hazards Commission Toka Tū Ake (NHC Toka Tū Ake) had received almost 10,000 claims for damage from landslides in the last three years, nearly ten times more than the previous three years when there were just over 1,000 claims lodged.
“The significant storms in recent years caused devastation to communities across the country,” says NHC Toka Tū Ake Chief Resilience and Research Officer Jo Horrocks.
“Landslide damage can be complex and costly to fix, and the insurance available for damaged land is limited. It’s really important to understand the risks, think about ways to protect your property and factor that into your financial planningbefore an event happens.”
NHC Toka Tū Ake currently receives more claims for damage due to landslides than
any other natural hazard. Since the Auckland anniversary floods in January 2023, losses from landslides have totalled $302 million –over four times the cost of all other natural hazards combined.
“For landslide damage, the natural hazards scheme covers up to the first $300,000 of damage to an insured home, and private insurance covers the rest up to the policy limit. There is also a limited contribution available for damage to land through the national scheme.
“However, the scheme can only cover up to the value of the insured land, up to ight metres around your home. For some homeowners, that won’t cover the full costs of repairing their land, especially when complex landslides have occurred,” Jo says.
“If you live on or near a slope, there are things you can do to identify signs of potential slipping and prepare your property. Consider getting advice from a geotechnical expert and keep an eye on your retaining walls and slopes to make sure they’re wellmaintained,” she says.
“It’s also important to understand the limits of cover for your driveway, consider if you can strengthen it against storm damage, and make plans in case your driveway gets washed away.”
If you live on or near a slope, there are things you can do to identify signs of potential slipping and prepare your property. Consider getting advice from a geotechnical expert and keep an eye on your retaining walls and slopes to make sure they’re well-maintained.
- Jo Horrocks.
If you’re buying a new property, you can also visit the Natural Hazards Portal for information on past claims related to landslides and other natural hazards, which could indicate future risk.
“A landslip may be triggered by heavy rain or earthquakes, with homes near hills or steep slopes most at risk. If you live near a hill or steep slope, watch out for cracks or movement that could be a warning sign,” the government’s natural hazards site reads.
“Make sure any retaining walls are well maintained, and look around to see if neighbouring retaining walls or slopes could affect your property.
“Keep a look out on your property for unusually angled retaining walls, small slips or rock falls, subsidence or bulges on or at the bottom of the slope, tilting trees or fences, cracks in the ground, retaining walls, driveways, footpaths or other hard surfaces, ground that’s become waterlogged, and water seepage at the bottom of the slope.
“It’s worth thinking about what would happen if a retaining wall failed. Consider who and what would be affected. How would you pay for repairs? The work may cost more than you might receive from natural hazards cover or your private insurance cover.”

Landslides occur when soil, rock, or debris moves downhill due to natural or humaninduced factors. In New Zealand, several key triggers contribute to the increasing risk of landslides, affecting homeowners and communities across the country.
Heavy rainfall and severe storms are among the most common causes of landslides. When the soil becomes saturated with water, it loses stability, making it more likely to slide. In recent years, extreme weather events such as the Auckland Anniversary floods in 2023 and Cyclone Gabrielle have caused widespread landslips, resulting in extensive property damage.
Earthquakes can also trigger landslides, particularly in areas with unstable terrain. The shaking of the ground can loosen soil and rock, causing slopes to collapse. In earthquake-prone regions, even small tremors can weaken land over time, increasing the likelihood of future landslides. Human activity, such as deforestation and construction on steep slopes, can make land more susceptible to landslides. Removing vegetation that stabilises the soil or altering natural drainage patterns can contribute to slope instability. Poorly designed infrastructure, such as roads or retaining walls, can also lead to unexpected land movement.
New Zealand’s geology plays a significant role in landslide risk. Many regions have weak or erodible rock formations that are more prone to failure, especially when exposed to heavy rain or seismic activity. Areas with steep terrain and soft soils are particularly vulnerable.
Climate change is expected to increase the frequency and severity of extreme weather events, leading to more landslides in the future. Rising temperatures and shifting rainfall patterns may contribute to more intense storms and prolonged wet conditions, further destabilising slopes.
Reducing landslide risk
Homeowners can take proactive steps to reduce the risk of landslide damage. If you live on or near a slope, regularly inspect your property for warning signs such as cracks in the ground, retaining walls, or driveways. Look for tilting trees, bulging soil, or water
seepage, as these could indicate potential land movement.
Ensuring that retaining walls are well maintained can help prevent soil from shifting. If you notice any signs of instability, seek advice from a geotechnical expert. Proper drainage is also crucial—diverting water away from slopes can reduce the risk of soil saturation and erosion.
If you are considering buying a property, check the Natural Hazards Portal for
information on past landslide claims in the area. Understanding the history of land movement in a location can help you assess future risks before making a purchase.
Insurance coverage for landslides in New Zealand is limited, so it is essential to understand what your policy includes. The national natural hazards scheme covers up to the first $300,000 of damage to an insured home, while private insurance covers the remaining cost up to the policy limit.
However, land cover is restricted to the insured area, typically up to eight metres around the home. In some cases, this may not be enough to cover extensive repairs. For homeowners living in high-risk areas, being prepared is key. Monitoring your property for warning signs, investing in preventive measures, and understanding your insurance coverage can help you minimise the impact of a landslide before disaster strikes.

Tradies are some of the hardest-working business owners out there. Long hours, demanding clients and the constant juggling of jobs leave little time for anything else, especially marketing. The physical toll of the work, combined with unpredictable schedules and tight deadlines, means most tradies are focused on simply getting through the day rather than thinking about business growth. It’s no surprise that marketing is often overlooked or seen as an unnecessary hassle.
But here’s the thing: not having a marketing plan is why so many good tradies are underpaid, stuck working for less than they’re worth and never building a business they can sell.
We see it time and again. Talented tradies rely solely on word-of-mouth, and while that can keep work coming in, it also keeps them at the mercy of unpredictable job flow. What’s worse, some tradies turn down good jobs simply because they’re too busy, sometimes overquoting to avoid work rather than just saying they’re booked out. It’s wasted time and wasted opportunity.
The best tradies are missing chances to amplify their business. That doesn’t mean hiring a big team or spending thousands on ads, it just means making small but strategic tweaks to how they market themselves. Done right, it can bring in better-quality clients, reduce quiet periods, and help them earn more per job.
Most tradies don’t need a fancy website, but they do need to show up where potential customers are searching. A Google Business Profile (GBP) is perfect for this. If you haven’t set one up, you’re invisible to customers searching for local tradies online. Setting up a GBP takes minutes but can make a significant difference in generating leads. A completed profile with job photos and positive reviews will rank higher and attract more enquiries. Encouraging satisfied clients to leave a review is a simple yet powerful way to improve credibility and visibility.
Social media can also be a goldmine for tradies if used correctly. Forget about the filters and heavily edited reels, there’s no need for daily updates or elaborate content. A basic Facebook and Instagram presence, with occasional before-and-after photos of completed projects, is enough to build trust and attract new customers. People love seeing transformation projects, and a simple caption with a call-to-action, such as offering free quotes, can go a long way. Local Facebook groups also present an opportunity to engage with homeowners who are actively seeking tradies. Commenting on recommendation requests or sharing service availability keeps a tradie top-of-mind in the community.
One of the most effective yet underutilised marketing strategies for tradies is referrals. Happy clients will naturally recommend a good tradie, but having a referral system in place can accelerate that process. Offering an incentive, such as a discount on future work for referrals, encourages past clients to spread the word. Business partnerships with builders, real estate agents, and property managers are another great way to secure consistent work without the hassle of constant marketing.
A common reason tradies lose jobs is failing to follow up on quotes. Often, a quote is sent out and then forgotten about, assuming the client will reach out if they’re interested. However, many customers get busy or forget, and the tradie who follows up first often wins the job. A simple text or email checking
in on a quote 48 hours after sending it can significantly increase conversion rates.
Some tradies assume advertising is expensive, but small, targeted ads can be highly effective, especially for urgent services. A well-placed Google ad targeting specific local search terms can bring in immediate calls, while a before-and-after transformation ad on Facebook can help attract long-term clients. With a modest daily budget, ads can generate high-quality leads without breaking the bank.
Beyond securing more work, a well-marketed tradie business becomes an asset. Many tradies don’t consider their business as something they can sell, but having a steady stream of clients, clear marketing processes, and a strong reputation can make it highly valuable to potential buyers. A business that

runs efficiently, with ongoing lead generation and repeat customers, is far more appealing than one that relies solely on the owner’s manual effort.
Marketing doesn’t have to be a full-time job or a huge expense. The best tradies already do great work, but making sure more people know about it is the key to business growth. With just a few small changes, tradies can take control of their marketing, secure betterpaying jobs, reduce downtime, and ultimately build a business that works for them.

Solar energy is booming in New Zealand, and if you’ve ever thought about making the switch, now might be the perfect time. More and more Kiwis are turning to solar panels to power their homes, cut electricity costs, and reduce their carbon footprint. But is it really worth it? What does your house need to be like to make solar energy work? And how much will you actually save in the long run?
It’s no surprise that solar power is gaining popularity here. With power prices constantly rising and an increasing focus on sustainability, many households are looking for alternative energy sources. In the last decade, the number of homes with solar panels has skyrocketed, and the technology has become more efficient and affordable than ever before.
New Zealand gets plenty of sunlight, making solar a viable option for homeowners across the country. In fact, cities like Auckland, Wellington, and Christchurch get as much or more sunshine than parts of the UK and Germany—both of which have far more solar installations than we do.
Not every house is an ideal candidate for solar power. The orientation and design of your home play a big role in how much energy you can generate. Ideally, your roof
should be north-facing to capture the most sunlight throughout the day, though eastand west-facing roofs can also work well.
The angle of your roof matters, too. In New Zealand, a pitch of around 30 to 40 degrees is considered optimal for solar panels, though most modern systems can still generate decent power even if the angle isn’t perfect.
One of the biggest reasons Kiwis are embracing solar is the potential for serious savings on electricity bills. By generating your own power, you rely less on the grid, meaning lower monthly costs. Some homes even produce more power than they use and can sell the excess back to the grid.
Beyond the financial perks, solar energy is a huge win for the environment. Unlike fossil fuels, it produces no greenhouse gas emissions, making it a cleaner, greener choice. Solar power also provides energy independence. If you pair your system with battery storage, you can keep your lights on even during power outages. For people in rural areas or those concerned about the reliability of the national grid, this can be a game-changer.
The upfront cost of installing solar panels in New Zealand varies depending on the size of the system and your specific needs. A typical home setup costs between $8,000 and $15,000, with battery storage adding another few thousand dollars to the equation.
That might sound like a lot, but consider the savings. Electricity prices in New Zealand are around 35 cents per kilowatt-hour and still increasing, while solar-generated electricity costs around 11 cents per kilowatt-hour over
the lifespan of the system. That’s a massive difference. Most solar panel systems pay for themselves in about five to eight years, depending on usage.
Of course, not everyone will see the same financial returns. If you use most of your power at night when the sun isn’t shining (and you don’t have battery storage), you’ll still need to buy electricity from the grid. However, for households that use a lot of power during the day—like those with electric vehicles, home offices, or high daytime energy consumption, solar can be a fantastic investment.
Unlike some countries, New Zealand doesn’t currently offer nationwide solar subsidies or rebates. However, some local councils have funding schemes that allow homeowners to add the cost of solar panels to their rates bill and pay it off over time. This can make the upfront cost more manageable.
There’s also the option to finance your solar installation through some energy companies
Here at ClearAir, our team consists of highly skilled and committed
and banks, which offer loans specifically for renewable energy projects.
The demand for solar power is only going to increase. As battery technology improves and costs continue to drop, more households will find it easier to make the switch. Largescale solar farms are also being developed, contributing to New Zealand’s renewable energy goals.
So, is solar worth it? It depends on your situation. If you own your home, have a suitable roof, and use a lot of power during the day, solar panels can be a fantastic investment. Over time, the savings can more than justify the initial cost, and you’ll be doing your part to help New Zealand transition to a cleaner energy future.
That said, if your roof isn’t ideal, you don’t use much electricity, or you plan on moving in the next few years, it might not be the best choice right now. But as technology evolves and energy prices continue to rise, solar will become even more attractive.

Sustainability is increasingly under the spotlight in the construction and demolition industry - from Government and local council resource consents and contractual requirements, to demand from private and corporate clients. But what does it mean to be sustainable and how can you apply it to your work?
What actually is sustainability?
Sustainability is a broad term covering a wide range of activities – it’s not just about hugging trees. It’s a holistic way to work which considers the broad-reaching impacts of our actions.
Being sustainable means meeting our current needs in a way which will last, and which won’t compromise whether future generations can meet their needs, too. Sustainability can be divided into three “pillars” - environmental, economic, and social.
Environmental sustainability
Environmental sustainability in construction and demolition is all about how we can build, demolish, renovate, rebuild, and landscape in a way which preserves our environment in the long-term. This might mean:
• Using principles of sustainable site planning and design at the beginning of a project
• Using materials made from sustainable renewable products or processes
• Making sure materials are used as efficiently as possible on
• Reusing materials again and again and again
• constructing buildings that have a minimal, or even positive, impact on the environment
There are plenty of easy ways to start reducing your environmental impact on construction jobs, which we are going to cover in more depth in future articles.
Economic sustainability
Economically sustainable businesses prioritise long-term value over short-term gains - focusing on efficient use of resources, equal sharing of wealth, and building resilience against economic shocks, such as earthquakes, droughts, or cyclones.
Balancing economic, environmental, and social outcomes can be challenging, but it’s worthwhile. Sustainability is a journey - you don’t have to do everything all at once.
You can improve your economic sustainability by investing in:
• renewable energy
• green technologies
• sustainable infrastructure that reduces environmental harm while creating economic value
• fair wages
• ethical labour practices
• equitable access to opportunitiesbecause economic growth should benefit all members of society.
Social sustainability
What sets social sustainability apart from the other two pillars is that it relates directly to people, focusing on the importance of human sustainability, both now and in the future. It means thinking about your staff as whole people with lives outside of work, not just another resource when they’re on the clock.
Key aspects of social sustainability include:
• Equity and justice: Equity acknowledges everyone starts at a different level. You wouldn’t expect a healthy builder and one with an injury to perform equally. They can both work, but with some adjustments
• Diversity and inclusion: This is about hiring people from different backgrounds, and valuing, respecting, and celebrating differences
• Community engagement: Encourages participation by your team in decision making
• Livelihood security: Ensuring stable employment and income for individuals
• Quality of life: Things like subsidised health insurance, consistent working hours, and flexibility for family commitments
• Cultural preservation: This is about maintaining and respecting cultural heritage. Encourage your team to embrace their cultural heritage on site.
The waste hierarchy
There are lots of ways to tackle your waste, but best practise uses the waste hierarchy. So, what is the waste hierarchy? It’s a super-easy framework to help you decide how to deal with materials, so they maintain the highest value possible throughout their lifetime.
The circular economy
At the heart of the waste hierarchy is a thing called the circular economy, which is just a different way of thinking about the way we make, use, and dispose of products.
In the cycles of our natural world, nothing is wasted – the ingredients of all living things are continuously absorbed back into a regenerative, circular system.
At the moment, we use a linear economy (with a bit of recycling), which focuses on getting products to the consumer as cheaply as possible.
To make the most of the resources available to us, we need to shift to a circular economy, which is one where we keep materials in use, at their highest value possible, for as long as possible.
Putting it into practice
There are lots of ways you can be more sustainable in your work as a builder or contractor. You could do this by:
• Using electric tools
• Reducing wastage during your builds (we’ll cover this in more detail in future)
• Building good quality, warm, and dry homes
• Participating in community events or charities
• Paying living wages and looking after your employees’ wellbeing. - This content is brought to you by 3R Group, in partnership with Mitre 10 Sustainability on Site and BRANZ. For more information on how to be more sustainable on your building sites, head to www.mitre10.co.nz/trade/sustainability &
Hard water is a common issue in New Zealand, particularly in areas where the water supply contains high levels of minerals like calcium and magnesium. While not a health hazard, hard water can be a challenge for plumbing systems, appliances, and construction projects. Understanding how it affects plumbing and how to mitigate its impact is essential for builders, plumbers, and property developers aiming to deliver long-lasting, highquality results.
One of the biggest issues with hard water is scale build-up. As water moves through pipes, taps, and appliances, the minerals it carries can settle and form deposits. Over time, this leads to blockages, reduced water pressure, and decreased efficiency in water heaters and boilers. In extreme cases, scale build-up can result in costly repairs or even complete pipe replacements. For commercial projects and large-scale developments, these maintenance costs can add up quickly, making it critical to address hard water from the outset.
Hard water is particularly tough on plumbing fixtures and appliances. Water heaters, dishwashers, and even simple tap fittings are all vulnerable to mineral deposits. Heating elements in water heaters become coated in scale, reducing efficiency and leading to higher energy costs. Taps and showerheads can clog, affecting water flow and functionality. In new builds, ignoring hard water can result in homeowners or business owners dealing with ongoing maintenance issues, which could reflect poorly on the construction team responsible for the project.
New Zealand plumbing standards recognise the importance of water quality in maintaining efficient plumbing systems.
The New Zealand Building Code (NZBC) includes requirements for potable water systems that ensure long-term performance and reliability. While it doesn’t explicitly mandate hard water treatment, it does require that plumbing installations be durable and meet performance expectations over time. This means that construction professionals should consider hard water solutions as part of their best practices. The NZBC places a strong emphasis on water safety and efficiency, ensuring that potable water systems meet strict hygiene and usability standards. Adherence to these standards is crucial for builders and plumbers to ensure compliance and avoid potential legal issues. Local councils may also have additional regulations regarding water treatment, depending on the region’s water quality. Developers working on highend residential and commercial projects, in particular, should prioritise hard water management strategies to improve water efficiency and overall system performance.
One of the most effective ways to combat hard water is through water softening systems. Traditional water softeners use ion exchange to replace calcium and magnesium ions with sodium, preventing scale build-up and keeping pipes and appliances functioning efficiently. While effective, these systems require regular maintenance, and there’s an ongoing cost associated with replacing salt. Some regions in New Zealand also have restrictions on water softeners that discharge excess sodium into wastewater systems, so it’s important to check local regulations before installation.
Another increasingly popular option is electronic or magnetic water conditioners. These devices alter the structure of mineral deposits, preventing them from forming scale inside pipes and appliances. While they don’t remove hardness minerals from the water entirely, they can significantly reduce build-up and prolong the lifespan of plumbing systems. For commercial and largescale projects, these systems are attractive because they require little maintenance and don’t involve chemicals or ongoing costs.
The NZBC places a strong emphasis on water safety and efficiency, ensuring that potable water systems meet strict hygiene and usability standards. Adherence to these standards is crucial for builders and plumbers to ensure compliance and avoid potential legal issues.
Contractors can also consider installing whole-house filtration systems that incorporate carbon filters alongside water conditioners to improve overall water quality. These systems not only address hard water but also remove chlorine, sediment, and other impurities, ensuring that both plumbing systems and end users benefit from cleaner water. This is particularly valuable in high-end residential and commercial projects where long-term durability and customer satisfaction are key priorities.
For construction professionals working in regions with particularly hard water, proactive measures during the build can make a big difference. Using PEX or stainlesssteel piping instead of traditional copper can help mitigate some of the issues caused by mineral build-up. Ensuring that water heaters and boilers are properly maintained and periodically flushed can also prevent excessive scale accumulation. Educating clients about the benefits of water softening solutions and offering them as an optional upgrade can add value to a project and improve customer satisfaction.
Hard water is a persistent issue, and it’s not going away anytime soon. Construction professionals who factor in water quality during planning and development will ultimately deliver more reliable, efficient, and long-lasting projects. By integrating water softening and conditioning solutions into builds, the industry can reduce maintenance costs, improve plumbing performance, and ensure that clients enjoy hassle-free water systems for years to come.

If you’ve ever wondered what would happen if you blended the practicality of a work ute with the performance of a sports car and the efficiency of an electric vehicle (EV), then the BYD Shark 6 might just be what you’d imagine.
This plug-in hybrid ute is setting a new standard in New Zealand’s traditionally diesel-dominated pickup market.
Performance that surpasses expectations
It’s fair to say that, as the first plug-in hybrid ute to hit Kiwi shores, the BYD Shark 6 has made a strong impression. The Launch Edition Premium AWD model, which sits alongside heavyweights like the Ford Ranger Sport 2.0 and Toyota Hilux SR5 Cruiser, packs a punch with a combined power output of 321kW from its 1.5-litre turbocharged petrol engine paired with dual electric motors.
The result? An impressive 650Nm of torque and acceleration from 0 to 100km/h in just 5.7 seconds – figures that might make even some sports cars envious.
But the Shark 6 is more than just a powerhouse on the road. It offers up to 100km of pure electric range and a combined
range of 800km, making it a great option for long trips or city commutes. The towing capacity, while not matching diesel rivals at 2,500kg with trailer brakes, is still more than adequate for most needs.
Cutting-edge hybrid technology
At the heart of the Shark 6 is its Super Hybrid technology. This cutting-edge powertrain combines a 1.5-litre turbocharged engine with dual electric motors, achieving performance akin to a 4.0L V8 engine but with far fewer emissions.
With the EHS (Electric Hybrid System) and a dedicated all-wheel-drive powertrain, it offers a thrilling driving experience without sacrificing fuel efficiency.
The BYD Blade Battery, a lithium-ion phosphate (LFP) battery, ensures longerlasting power, increased range, and improved safety compared to traditional designs. This
battery technology makes the Shark 6 a true game-changer in the world of hybrid utes.
As you’d expect, the Shark 6 is packed with modern tech. The V2L (vehicle-to-load) function allows the ute to transform into a mobile power station, making it ideal for powering tools on job sites or providing electricity in off-grid locations.
Inside, the Shark 6 features an impressive 10.25-inch LCD instrument panel and a rotating 15.6-inch adaptive screen that provides a futuristic and intuitive driving experience. The cabin is designed with
Premium Launch Edition: $69,990
EV Range: Up to 100 km
Fuel Economy: 2.0/100km
Combined Range: Up to 800 km
comfort in mind, offering heated, ventilated, and electrically adjustable front seats, as well as rear seats that recline by 27 degrees – a feature rarely seen in traditional utes.
Beyond its performance, the Shark 6 doesn’t skimp on comfort. The interior blends luxury with utility, offering what you could say is a refined experience in a traditionally rugged segment, ensuring a comfortable ride, whether you’re navigating city streets or heading out for an adventure.
The Shark 6 integrates the ultra-high safety Blade Battery along with a high-strength steel frame, thanks to BYD’s CTC technology, ensuring occupants are protected in the event of a collision. The vehicle also comes with a range of advanced safety features, including hill hold control, vehicle dynamic control, and hill descent control, providing enhanced peace of mind for drivers.
The BYD Shark 6 is something entirely new for the New Zealand ute market, bridging the gap between traditional ute capability and the modern demand for hybrid efficiency.
While its towing capacity might not match that of its diesel counterparts, the Shark 6 offers impressive performance, genuine electric-only range, and a suite of innovative features that make it a compelling choice for city tradies, lifestyle buyers, and anyone looking to reduce their carbon footprint without sacrificing utility.
Competitively priced against high-spec traditional utes, it delivers a sophisticated blend of power, technology, and efficiency that could very well reshape what people expect from a modern ute.
For those ready to embrace electrification without compromise, the Shark 6 is worth serious consideration.
Weathertightness is key not only for the comfort and health of occupants but also for the longevity and durability of the building itself.
Weathertightness refers to a building’s ability to resist the entry of water from the outside environment, like both rain and ground moisture. This is important because water infiltration can lead to a number of problems, such as mould growth, structural deterioration, and insulation damage, which can impact both the integrity and liveability of a structure.
To future-proof buildings against these issues, a number of strategies can be used.
First and foremost, the building’s design should have sufficient drainage and prevent the possibility of water pooling. This means having properly sloped roofs, decent-sized gutters, and downspouts that lead water away from the building’s foundation.
The selection of materials plays an important role. Materials that are resistant to moisture and can withstand the local climate conditions are more ideal. For example, using water-resistant barriers and seals around openings such as windows and doors makes sure that these points do not become gateways for moisture entry.
Regular maintenance is crucial in maintaining weathertightness. This involves checks and repairs of roofing materials, seals, and drainage systems to ensure they remain in top condition, maintaining water tightness.

By using considerate design, choosing suitable materials, and maintaining them, buildings can be properly future-proofed against water damage. This not only increases the structure’s resilience but also ensures the health and safety of its occupants, in the long run contributing to the building’s sustainability and efficiency over time.
Reclaimed timber is gaining ground in New Zealand homes, and it’s easy to see why. It’s got rustic charm, rich history, and eco-friendly appeal; it brings something truly special to residential projects that standard building materials often lack.
At its core, reclaimed timber is wood that has been salvaged from previous uses, often taken from old buildings, railway sleepers, barns, or industrial sites. Instead of being discarded, it’s cleaned up, treated if necessary, and repurposed for use in everything from flooring and benchtops to ceiling beams and bespoke furniture. What makes it stand out isn’t just the sustainability factor, though that’s a big part of it, it’s also the look, the feel, and the durability of the material.
Using reclaimed timber in a residential project is a conscious step towards sustainability. By choosing timber that’s already been cut, used, and discarded, homeowners help reduce the demand for newly harvested wood. That, in turn, helps preserve forests, lower carbon emissions, and minimise construction waste. For Kiwis wanting to make greener choices at home, reclaimed timber is a smart and meaningful one.
Every piece of reclaimed timber is unique, marked by its past life: weathered textures, nail holes, saw marks, and a natural patina developed over time. These imperfections are exactly what make it beautiful. They give the timber a personality and authenticity that factory-milled, brand-new timber simply can’t match. When used in a home, it adds depth, warmth, and a sense of lived-in comfort, even in brand-new builds.
Durability is another major factor behind reclaimed timber’s popularity. Much of it comes from old-growth trees that were
slower to mature, making the wood denser and more stable than many of today’s faster-grown varieties. And because it’s already been exposed to decades of use and environmental change, it tends to be more dimensionally stable—less prone to warping, splitting, or shrinking over time. That makes it ideal for high-traffic areas like flooring or structurally exposed areas like beams and mantels.
What’s also appealing is how well reclaimed timber blends with different architectural styles. It’s at home in a country cottage, adds

warmth to a sleek modern townhouse, and can even soften the hard edges of industrial design. Whether used in small touches or bold statements, reclaimed timber creates focal points that are both stylish and meaningful.
Beyond the visual and practical benefits, there’s a deeper appreciation that comes with choosing reclaimed timber. It carries a sense of history and heritage that resonates with people. Knowing that your kitchen benchtop once served as flooring in an old train station or that your dining table came from a historic building adds an emotional layer to your home’s story.

The Government has confirmed that homeowners will soon be able to build granny flats up to 70 square metres without needing building or resource consents.
The reform, a key plank of the National–NZ First coalition agreement, aims to reduce red tape and boost housing supply by making it easier and more affordable to build minor dwellings on existing properties.
The change follows a wave of public support and is backed by nearly 2,000 submissions during consultation run by the Ministry of Business, Innovation and Employment (MBIE) last year. Initially, the Government proposed a 60 square metre limit, but extended it to 70 square metres in response to feedback.
“It was the public submissions asking, ‘Why not a bit bigger?’ and I mean, it’s a fair question, where you draw the line,” said Building and Construction Minister Chris Penk. “You actually don’t have any greater risk at a slightly larger footprint of the building.”
The new 70 square metre cap significantly expands the functional potential of these small homes. While 60 square metres typically allows for a one-bedroom layout, 70 square metres can accommodate two bedrooms—making the units more suitable for families, elderly relatives, or young adults seeking independence.

While 60 square metres typically allows for a one-bedroom layout, 70 square metres can accommodate two bedrooms— making the units more suitable for families, elderly relatives, or young adults seeking independence.
Under the proposed amendment to the Building Act, expected to be introduced in mid-2025, granny flats will be exempt from building consents if they meet specific criteria. The dwelling must have a simple design, comply with the Building Code, be built by authorised professionals, and be registered with the local council both before and after construction.
Importantly, the exemption applies only to new builds that follow the final specifications; it does not cover any existing or currently underway projects.
“We have carefully considered the feedback to make sure the path forward strikes the right balance between enabling housing growth and managing risks,” said Penk.
Complementing the Building Act amendment is a forthcoming National Environmental Standard (NES) under the Resource Management Act (RMA), which is expected to be in force by the end of 2025. The NES will override local council rules, allowing granny flats in both rural and residential zones without needing resource consents.
“This NES will require all councils to permit a granny flat on sites in rural and residential zones without the need to gain a resource consent,” said Housing Minister Chris Bishop. “These processes are [currently] complicated, time-consuming, and costly.”
Bishop described the broader changes as a direct response to New Zealand’s pressing housing shortage. “It’s currently far too hard to build the homes New Zealanders need, with even the simplest dwellings tangling up homeowners and builders in red tape.”
While the reforms simplify the path to building, they do not eliminate all regulatory obligations. Homeowners will still be subject to infrastructure charges, levied through the existing Project Information Memorandum (PIM) process. These charges are meant to support councils in funding local infrastructure for growing communities.
MBIE has estimated that nearly 13,000 additional granny flats could be built over the next decade under the new exemption.
The move is part of a broader effort by the coalition government to address housing
demand through deregulation. NZ First Associate Finance Minister Shane Jones, who represents Northland, highlighted the social motivations behind the change.
“In the Far North I saw how extended family often live together at the same property,” Jones said. “Changing the rules to make it easier to build more family accommodation allows generational living at an affordable price.”
The new rules cater to a growing trend toward multi-generational households and the need for accessible housing for young adults, elderly family members, and rural workers.
The legislation is on track to be introduced in the coming months, with full implementation expected by the end of 2025. Until then, homeowners are advised to check with their local council before proceeding with any building plans.
As New Zealand continues to grapple with an ongoing housing crisis, the government’s targeted deregulation could mark the beginning of a broader shift in how New Zealand approaches residential development.
“Removing regulatory barriers and taking a common-sense approach to the consenting system is a critical part of increasing housing supply for Kiwis,” said Penk. “We want to get builders back on their tools, and out of the office by reducing their paperwork.”
Almost without exception, technical specifications call for concrete to be cured, however the process is not always undertaken correctly.
Why cure concrete?
Curing is the name given to procedures that promote the hydration of cement. The following focuses on the control of moisture movement, although temperature control is also needed.
When water is added to cement, a complex chemical reaction occurs which hydrates the cement, and in time produces a firm, hard mass. This reaction continues when water is present. If the water is removed, the reaction stops, which results in the cement being only partially hydrated.
Concrete is therefore cured to control the rate and extent of moisture loss during cement hydration.
What are the advantages?
Moisture-loss from the surface of concrete has the potential to impact on the strength and durability and cause early age cracking. The strength of concrete is predominantly determined by the water/cement ratio and the degree of hydration. If premature drying occurs, the hydration process will stop, and the desired strength of the concrete will not be attained.
To appreciate this, it’s useful to visualise the chemical reaction of cement and water as a process whereby thin needles begin to grow out of each grain of cement after water is added.
As these needles grow, they become intertwined and it’s this interlocking process that gives concrete its strength. If the water dries up, the needles stop growing and less intermeshing occurs, resulting in loss of strength.
Therefore, inadequate curing can result in a weak concrete surface, which may wear under the abrasive action of traffic.
Curing will also impact on the ability of the concrete to protect the reinforcement from corrosion.
The greater the time water is present, the more intertwined the cement needles will

become and the denser the concrete cover will be. This will make the concrete cover more watertight, and will increase the time it takes before the conditions around the reinforcing bar cause corrosion.
Another important feature of curing is its impact on the potential for early age
cracking, which occurs when tensile stresses in concrete exceed its tensile strength. Tensile stresses can develop in the surface of concrete when the top dries and starts to shrink, while the saturated core of the concrete resists against the surface. If curing doesn’t commence as early as possible, moisture can escape from the pores of the concrete that are near the surface. This creates negative pressure in the capillaries, causing the solid particles to draw closer together (shrinkage). If curing prevents moisture escape, surface shrinkage will be avoided, and the concrete is given the chance to gain some strength with time.
What are the options available?
Methods of curing concrete fall broadly into the following:
• Those that minimise moisture loss from the concrete by covering them with relatively watertight membranes
• Those that prevent moisture loss by continuously wetting the surface.
Which is best?
This depends on the project, however a few things to keep in mind are:
• If using water curing, the surface must be kept continuously moist. Ensure that runoff water doesn’t enter streams or the storm water system as it may have an adverse effect on aquatic life
• Curing with polythene may result in some discolouration of the surface. The effectiveness of this curing method is greatly reduced if it’s not kept securely in place
• Membrane curing compounds may not be compatible with subsequent coverings. They can also exist on the surface for a long time meaning it may take time for the slab to dry sufficiently to apply adhesives and surface coverings such as vinyl. There is also a finite window of application, typically when the bleed water is no longer rising to the surface.

The new range of MAX® TwinTier™ Rebar-Tiers can tie rebar faster and with more power than ever before! These are the sixth generation tools from MAX® Japan and by far the best!
Three new generation MAX® Rebar-Tiers make up the TwinTier™ range, introduced with three new design features to provide the greatest efficiency and highest level of safety for reinforcing ironworkers.
The TwinTier's "dual wire feeding mechanism" increases tying speed by reducing the time needed to twist and feed the wire, consequently reducing the cost, and shortening the time required for construction. The tool’s dual-wire wrap ensures each tie is reinforced for maximum hold.
The TwinTier's “wire pull back mechanism” firmly pulls the tie wire in to adjust the tie to the rebar’s size to maximize the strength of the tie. When forming a tie the tool makes a loop with the wire and then pulls the wire to tightly secure and lock the rebar in place.
The TwinTier's “wire bending mechanism” feeds a precise amount of wire to match the thickness of the rebar being tied and
cut down on the use of unnecessary wire. This bending mechanism consistently feeds, pulls back, twists and releases the perfect sized tie for each application.
The TwinTier's quick load magazine makes changing wire spools a piece of cake, and its frontward position provides improved balance/ ergonomics, making flatwork easier.
This generation of the MAX® Rebar-Tiers produce ties that are approximately 50% shorter in height, allowing for thinner concrete pours. Also, the ends of each tie are positioned downward to increase safety. Additionally, wire spools now produce up to 240 ties (when tying D12 x D12 rebar).
• The RB441T Rebar Tier is designed to tie D10 x D10 up to D22 x D22 rebar
• The RB611T Rebar Tier is designed to tie D16 x D16 up to D29 x D32 rebar
• The RB401T-E Standup Rebar Tier is designed to tie D10 x D10 up to D19 x D19 rebar.
The TwinTier's quick load magazine makes changing wire spools a piece of cake, and its frontward position provides improved balance/ergonomics, making flatwork easier.
A low “battery power consumption” design allows the tool to produce 5000 ties per charge using a 5.0Ah, 14.4volt Lithium-ion battery, which recharges in just 60 minutes.
The tool’s 6-step torque adjustment dial allows its user to adjust the strength of the tie based on the application. Steel, electrogalvanized and polyester (“poly”) coated wire are all available for use with the MAX® TwinTier™.
The MAX® TwinTier™ works at double the speed and produces double the number of ties from a single roll of wire than the previous model and far exceeds that of any of its competitors.
Overall, no matter the application, the MAX® TwinTier™ reduces the time it takes to complete a job, saves businesses money by cutting man hours needed for each project and increases the productivity of its workers. For more information visit the SIFCO website - www.sifco.co.nz
Aquamax has expanded its infrastructure service offering with the addition of an Aquacutter hydro-demolition robot. Aquajet Systems, a Swedish firm, are the world leader in this technology.
Hydrodemolition is a process utilising ultrahigh pressure (1450 bar or 20,000 pounds per square inch) water blasting to cut away concrete without impact to surrounding structure or damage to steel reinforcing. Engineers specify hydrodemolition particularly when remediating or modifying existing concrete structure. Concrete is stripped away prior to welding in repairs or additions to the existing rebar. The process ensures there is no damage or microcracking of the existing concrete that might weaken the structure or reduce the pull-out performance of the rebar.
Hydrodemolition robots dramatically increase the productivity and safety margins of the hydrodemolition process by taking the operator off the gun. The machine is mounted on a tracked crawler chassis and is electrically powered. The operator controls the machine remotely via a wireless controller.
The machine can handle significantly higher reaction loads arising from the jet lance and therefore much higher fluid flow rates. There is a direct relationship between
the flow rate and productivity. Doubling the flow rate will result in twice as much concrete removal.
The Aquacutter receives high-pressure water from a large, containerized pump delivering 95 lpm at 20,000 psi. The pump is contained in a purpose-built sound-proof container which can be located up to 150 metres from the robot if required.
Manual gunning can be very tiring and requires operators to take plenty of breaks during the work day. The robot never tires and is just as productive at the end of the day as the beginning of the shift.
Manual blasting can deliver productivity in the range of 0.2 – 0.3 cubic metres of concrete per day. A robot can easily cut one cube per day representing a four to five-fold improvement. Manual blasting still

has a role, tidying up or reaching those hard-to-get places.
The robot is programmed to cut complex shapes with varying parameters depending on the situation. The waterjet lance is also ‘wobbled’ to simulate hand-gunning and reduce the likelihood of ‘shadowing’ –leaving uncut concrete behind rebar. The cutting head is mounted on an articulated arm that allows for blasting on horizontal, vertical and overhead surfaces.
In addition to hydrodemolition, the robot can also be fitted with a scabbling head with similar productivity benefits. The machine has been used to scabble large areas of sewer prior to re-surfacing. Weighing around a tonne, the robot is easily craned into tanks or onto upper floors of buildings.
Concrete NZ is pleased to announce that its Reinforcing Processors Stakeholder Group has achieved Sector Group status, significantly strengthening its ability to advocate for members, share technical knowledge, advance sustainability, and champion industry training.
This transition reflects the growing importance of reinforcing processors in New Zealand’s concrete and construction industries. By formally recognising their role, Concrete NZ ensures reinforcing steel processors have a unified voice in shaping industry standards, sustainability initiatives, and workforce development.
What is the Reinforcing Sector Group?
The Reinforcing Sector Group represents companies that specialise in processing reinforcing steel for concrete structures. The reinforcing processors act as the main link between major steel reinforcing manufacturers and the end-user of reinforcing materials. They provide the market with a one-stop processing shop for fabrication of steel reinforcement in accordance with relevant Standards.
The Reinforcing Sector Group is committed to:
• Advocating for the industryPromoting, developing, and protecting the interests of New Zealand’s steel reinforcing processors
• Industry coordination and representation
- Acting as a unified voice on sector matters, engaging with government
in conjunction with Concrete NZ, regulators, and industry bodies
• Standards and guidance - Supporting the development of technical standards and best industry practice
• Knowledge sharing - Disseminating technical and market information

With a focus on collaboration, technical leadership, and sustainable growth, the Group will play a pivotal role in the future of New Zealand’s construction industry.
Reinforcing steel's role in a lower-carbon future
The latest Concrete NZ Sustainability Report marks an important step forward by incorporating data from the reinforcing steel processing sector. As a critical component in precast and cast-in-place structures, reinforcing steel contributes to the strength and resilience of New Zealand’s built environment.
Building on the 2021–2022 baseline, the latest Sustainability Report provides updates on emission reductions, sustainability initiatives, and industry strategies for achieving net-zero carbon goals. Including reinforcing steel processors in industry-wide health and safety reporting demonstrates the sector’s commitment to transparency and sustainability. This expanded dataset strengthens the industry’s ability to track progress and benchmark improvements.
Like concrete, reinforcing steel in New Zealand is rapidly decarbonising due to technological advancements and increased use of recycled materials.
will:
• Increase recycled scrap steel use, reducing reliance on raw materials
• Leverage New Zealand’s largely renewable electricity grid to cut emissions
• Halve the embodied carbon of locally produced reinforcing steel.
This shift will reduce the embodied carbon of reinforced concrete by over 25%, all else being equal. Some New Zealand processors already offer imported rebar made from 100% recycled steel, providing further options for low-carbon construction.
With these advancements, New Zealand’s reinforcing sector is playing a key role in reducing construction emissions, reinforcing concrete’s position as a sustainable, resilient, and future-ready material.

Find out how to select the right eye protection, wear it, how it works, how to care for it and more.
It only takes a small accident to cause irreparable damage to your eyes.
ACC receives more than 9000 claims for workplace eye injuries each year. Many of those injured are left with long-term impaired vision and some are blinded.
Workplace eye injuries cost New Zealand more than $3 million every year – a figure which does not take into account lost productivity.
Under the Health and Safety at Work Act, employers are required to provide appropriate personal protective equipment, such as eye protection, where there is a risk of eye injury. They must also ensure workers are trained in when and how to use their eye protection, as well as how to maintain it. Workers must wear eye protection if required to by their employer and the request is reasonable.
Follow these steps to reduce the risk of eye injuries:
When to wear eye protection:
• Always assess the risk of work to determine if eye protection is necessary – can the risk be eliminated using other controls? What is the severity of the risk and the potential eye damage?
• Even if not carrying out a task with an obvious eye hazard, you may be at risk from others nearby. Always have your eye protection with you and if in doubt – wear it
• Remember to protect others from your welding work and never watch any welding processes unless wearing suitable eye protection
• Think about whether the work requires high impact protection
• Some work will require full face shield protection.
• Always wear eye protection when compressed air, hazardous substances, cartridge-fired tools, power tools, power washers, hand tools such as chisels are in use.
Maintenance and use:
• Ensure eye protection provided fits comfortably and is suitable for the job
• Look after any eye protection providedkeep it clean and store it in a soft case
• Report and replace any lost, damaged, or unserviceable eye protection
• Make sure the eye protection fully covers the eyes
• If needed, invest in prescription eye protection.
Under the Health and Safety at Work Act, employers are required to provide appropriate personal protective equipment, such as eye protection, where there is a risk of eye injury.
What should you do if you do receive an eye injury?
• Seek medical assistance should you get something in your eye or receive any sort of eye injury. Avoid rubbing the eye, as this can make it worse. Minor irritations can be treated by flushing the eye with sterile water (from a first aid kit).
• Record injury in accident register
• Ensure your supervisor is aware of the injury.

Opioid misuse is a growing global issue and New Zealand is now seeing an increase in workplace detections.
The Drug Detection Agency’s (TDDA) latest Imperans Report additionally revealed that opioid use accounted for 12.1% of positive workplace drug tests from October to December 2024, up from 11.9% in the same period of 2023.
Conducted by Massey University, the 2024 New Zealand Drugs Trends Survey found that 27% of respondents reported nonmedical use of pharmaceuticals in the past six months. The issue is nationwide, with Southland and West Coast reporting the highest levels of prescription opioid misuse.
Until recently, it looked like New Zealand was avoiding the opioid crisis seen overseas, but that’s changing. Smart builders and contractors know that any increase in opioid detections represents a serious workplace threat. Whether legally prescribed or illicitly obtained, opioids can cause workplace accidents, addiction and long term issues, and even the loss of life. The data overall is signalling that employers need to take action.
As New Zealand’s largest workplace drug testing provider, TDDA is doing just that, and to help keep people safe it has expanded its drug screening capabilities.
TTDA has introduced testing for tramadol and fentanyl — two high-risk opioids that pose serious workplace safety concerns worldwide. For the first time in New Zealand, these substances will be included in enhanced oral fluid and urine screening devices, eliminating the need for costly independent testing technology.
The data overall is signalling that employers need to take action.
This industry-leading TDDA R&D innovation expands its standard screening panel from seven to nine drug types, and at no additional cost. The updated devices, verified by an AS/ NZS 4760:2019 & AS/NZS 4308:2008 accredited laboratory, will help businesses proactively mitigate risks associated with these potent substances and help contractors remain compliant with health and safety law.
TDDA monitors global drug trends to ensure workplaces stay ahead of emerging risks. The rising presence of tramadol and fentanyl demands action, and that’s why it is now providing businesses with advanced detection capabilities. By integrating the technology into its screening devices, it gives businesses the tools to protect their workforces.
Drug and alcohol policies differ from business to business, so to provide flexibility, it has implemented an opt-in/ opt-out process through its Imperans IT platform, allowing businesses to tailor their testing requirements.
Opioids are serious substances, so TDDA is urging businesses to take a proactive approach to workplace safety through implementing comprehensive drug testing programmes, including pre-employment, reasonable cause, and random drug and alcohol testing. As a leader in workplace drug detection, TDDA is committed to helping businesses stay ahead of these challenges, fostering safer and more productive workplaces. Afterall, a drug-free workplace is essential not just for legal compliance but for maintaining a strong, safety-first culture.

Founded in 2010, Summit Scaffolding has quickly grown to serve the Auckland, Northland, Waikato, and Bay of Plenty regions. This expansion is largely due to the company’s well-earned reputation for providing a comprehensive and reliable response to every project, no matter the size.
Summit specialises in all aspects of scaffolding, including civil, commercial, industrial, and residential work. However, it is particularly well-known for its extensive commercial projects and a significant residential division.
Summit Scaffolding’s directors, John Scott and Bruce Pickerill, share, “Our key business achievement is keeping all of our clients happy. That’s no matter what size they are – the biggest construction company in the country or Mr. and Mrs. Smith doing up their house in the suburbs.
“To us, what matters is their satisfaction. Our target customer base is everyone who requires safe scaffolding. We don’t cherrypick. Anybody that requires a safe scaffold solution is our target customer base.”
The company uses a hands-on approach to fully understand each project, allowing the team to customise scaffolding solutions tailored to specific needs.
The process begins with a site visit to assess the project, followed by designing a plan with timeframes and costs to ensure the job is completed correctly and safely. From there, the team gets to work.
“We go over and above the industry practice guidelines. Also, all of our management comes from a scaffolding background. Our managers have worked all over the world, and our basic knowledge would be unsurpassed in New Zealand,” John explains.
Summit Scaffolding’s management team brings an average of 28 years of experience to the table. John started his scaffolding career at 16 while studying civil engineering in the United Kingdom. He spent 18 years working across all aspects of scaffolding, including commercial, residential, and marine scaffolding, primarily in the London area.
Bruce began his scaffolding career in Sydney before returning to New Zealand, where he took on management and franchisee roles with Pacific Scaffolding in Auckland. In 2010, both joined Summit Scaffolding and played a pivotal role in its development into the successful company it is today.
In addition to scaffolding services across multiple sectors, Summit Scaffolding offers equipment for hire and sale through Kwikserv, an internationally recognized supplier of premium scaffolding products. The company also provides propping and shore loading services.
A culture of safety and career growth
One of the main factors behind Summit Scaffolding’s success in the construction industry is its commitment to ongoing staff training, ensuring the company stays ahead of the curve. Summit takes the lead in this regard, going well beyond standard certifications.
At a minimum, all of Summit’s installers hold up-to-date Site Safe cards. Supervisors, on the other hand, hold Site Safe Gold Cards. This, combined with international qualifications and extensive experience, guarantees that Summit’s sites and workers maintain the highest safety standards.
Summit operates within the SARNZ (Scaffolding, Access and Rigging New Zealand) framework and adheres strictly to all scaffolding practices, health and safety, and employment regulations set by the Government.
The company attributes much of its success to its positive company culture, emphasising ongoing training, development, and safety practices to maintain a “professional, polite, and loyal” workforce.
As John explains, “We pride ourselves on building up a good skill base with a diverse group of employees. Being able to employ people and give them a career path gives
them something to aim for. That can all be achieved within Summit. We always try to promote from within. We try to give our guys a place where they can realise their ambitions with us.”
Looking toward the future, both John and Bruce agree that Summit Scaffolding will continue to grow while upholding the rigorous safety standards and practices that have positioned the company as a leader in the industry.
Construction pricing is balanced between being competitive in a market that is slim on projects, and at a sustainable level for the business.
The recent school lunch provider collapse shows the dangers of unsustainable pricing. Bidding for, or accepting contracts at prices below sustainable cost, leads to unintended consequences and failures.
The collapse of school lunch provider Libelle, soon after winning a Government contract, shows what happens when contracts are awarded primarily on price, with little consideration for the real cost structure, longer term sustainability, service quality, or viability. The purchaser chasing lower costs, has a duty to ensure the price and product can be delivered long term.
Libelle was required to scale up fast from 20,000 to 125,000 lunches per day, while the Government cut the budget from $9 per meal to $3. That’s not a sustainable business model, quality meals could not be produced at that price.
This resulted in the incumbent provider losing their contract, the new provider failing, low product quality, disruption, and a setback for the program.
Attributes of these pricing tactics are evident in the construction industry, with pricing below the cost of labour and materials to secure contracts in an increasingly competitive market. Simple logic: win the contract, figure out how to make it work later. The reality may be contractors are: forced to cut corners; deliver sub-par work; go out of business; or leave clients with unfinished work, remediation, costly delays and disputes, or ‘needing new’.
Contract pricing is better driven by good faith bargaining and an emphasis on sustainable and mutually beneficial relationships, between parties.
When selecting suppliers, ask yourself: What do I truly value? The lowest price from anyone, or do enduring relationships, trust, integrity, goodwill, customer care, productivity, quality, reliability, and efficiency matter just as much?
A trusted supplier who understands your needs, delivers results, and supports your business through challenges may be worth far more than short-term savings. The cheapest option today, may cost more later.
We had a contractor do a job for us recently, at short notice. They really needed the work, we didn’t desperately need it done, but we agreed at a fair price – and to a few variations, and price adjustments on the way through. We
know they will work for us in the future, and it was worth the investment to support them now. The price could have been squeezed for sure, but we just don’t think it’s great business.
Long-term supplier relationships bring value beyond just price, offering trust, consistency, knowledge of your needs, and reliability during tough times. Breaking that bond for short-term cost savings can ultimately lead to increased risks, lower service levels, and financial repercussions. Businesses should weigh up the risks of short-term savings versus long-term stability, before making supplier changes based on price alone.
Perhaps now more than ever we should consider procurement policies and contract negotiations in a sustainable way that accounts for quality, longevity, and fair compensation. Government and large-scale buyers should recognise the lowest bid may not always the best option.
Instead of engineering contracts into financially impossible positions, your business might focus on and consider:
• Realistic cost structures that include fair wages and overheads
• Long-term supplier relationships built on trust and mutual benefit
• Service-level agreements that prioritise quality, not just cost savings
• Indexing contracts to inflation and supply chain fluctuations.
The collapse of Libelle should serve as a warning: when the pricing strategy ignores the long-term objective of the contract, the inevitable results.
A race to the bottom in pricing, is ultimately a race to failure, for all. Equally we expect when times are good, if you overcharge – this is not sustainable either, for loyalty or goodwill.

Founded in the early 2000s, the Frame and Truss Manufacturers’ Association (FTMA) represents the vast majority of frame and truss manufacturers across the country.
FTMA’s Member Services executive, Peter Carruthers, explains that the association was created in response to challenges such as non-compliance and poor quality in the industry.
“A number of the manufacturers thought they better get together and sort it out,” Peter says, which led to the formation of FTMA along with a code of conduct.
“We promote good standards of business operation and conduct and we look for certain minimum operational standards or qualities.
“For example, we look at health and safety policies and evidence of a working system. We’re not expecting worldclass systems, but we’re looking to see if a company has policies in place and is monitoring its own performance.”
FTMA also seeks evidence of how members handle and resolve customer complaints. Peter believes this reflects the quality of an operation that serves customers well and takes care of its employees. “It’s fairly standard. Many other industry associations would do that,” says Peter.
In addition, FTMA supports its members in understanding new building codes and updates. The association has played a role in the government’s development of the Building for Climate Change code, which aims to reduce greenhouse gas emissions from the building process.
“Frame and truss manufacture is very efficient, but a lot of the waste may be from packaging materials. All the timber comes with plastic wrap for rain protection and all this wrap ends up places. So, the question is; what can be done to better manage it?” Peter explains.
By fostering communication across sectors, FTMA helps to break the isolation that can occur within individual industries, allowing for easier collaboration and problem-solving.
“Points of contact might not need to be frequent, but with communication between the various sectors, hopefully over time we can iron out bugs, so at the end of the day everyone is happier and there are fewer callbacks and stuff-ups,” he says.
Peter emphasises the importance of employee engagement in maintaining strong teams: “Having employees not just coming along because they need a job but because they’re engaged and committed to the business is vital.”
He points out that when tough times arise, such as covering absences or working extra hours, a solid team becomes crucial.
“It’s not easy by any stretch of the imagination; there has been lots of disruption. But it brought into focus that members need to have that resilience in their operations and employees so they can better survive.”
Like many sectors in the construction industry,
“Companies are thinking about ways to reduce exposure to labour by investing more in equipment and automation so reducing the human hands needed,” he explains.
“It’s doing away with jobs but that is what people have to do to be competitive. They’re continuously looking at improving quality and reducing time and thinking about what more can be done off-site.”
While frame and truss manufacturing is already an offsite process, companies are exploring further innovations.
“They’re asking themselves; can they add more details or services to the basic frame and truss? It’s important but difficult because there’s investment required. It’s more complex, there are more compliance issues, and additional skills are needed,” Peter says.
To support skills development, FTMA helps wherever possible by providing access to useful information. “A lot of drive is coming from the FTMA members and they’re all trying to make the industry better for themselves and their customers,” Peter concludes.
I would give a lot of credit to the government and what they’ve done in facilitating training, such as the fees-free scheme. The number of people going through apprenticeships has increased strongly. It’s better, but we want to see more.
closely with training organisations. The association works with the Building & Construction Training Organisation to promote workforce training and upskilling among its members.
Peter shares that several FTMA representatives are part of the group that sets the curriculum for apprenticeships, ensuring that apprentices receive relevant and current training.
“I would give a lot of credit to the government and what they’ve done in facilitating training, such as the fees-free scheme. The number of people going through apprenticeships has increased strongly. It’s better, but we want to see more.”
Reflecting on recent challenges, Peter notes that many FTMA members, along with others in construction, are feeling the strain of staff shortages and skills gaps.

The Crane Association of New Zealand is proud to announce its 2025 Annual Conference, taking place from 16–18 July at the spectacular Tākina Wellington Convention and Exhibition Centre. This year’s event carries special significance as it marks the 50th anniversary of the Association, a milestone that offers the perfect moment to reflect on our history, honour those who have helped shape the industry, and look ahead to a strong and resilient future.
Founded in 1975, the Crane Association has been the cornerstone of New Zealand’s lifting and heavy equipment industry for half a century. It has played a vital role in supporting operators, improving safety standards, promoting training and development, and advocating for the interests of its members nationwide. As we celebrate 50 years of progress, we also acknowledge the critical contribution cranes and those who work with them make to the New Zealand economy—on construction sites, in infrastructure projects, energy generation, ports, logistics, manufacturing, and more.
This year’s conference promises to be one of the most exciting and ambitious in the Association’s history. With growing interest from local and international exhibitors, the trade exhibition will showcase the latest in crane technology, lifting solutions, safety systems, and support services. Notably, several overseas companies will be exhibiting in New Zealand for the first time, underlining the country’s significance as a market and our industry’s growing global connections. The three-day event will be packed with industry insights, thought-provoking panels, technical updates, and networking
opportunities. In a time when businesses are navigating economic challenges, regulatory changes, and evolving workforce needs, the conference offers valuable space for connection, conversation, and collaboration. It’s a chance to regroup, learn, and gain fresh perspective—together.
Elevating the significance of this year’s gathering is a special evening event at Parliament, hosted by the Hon. Christopher Penk, Minister for Building and Construction. Taking place during the conference, this occasion reflects the growing recognition at the highest levels of government of the crane sector’s contribution to national productivity and development. The presence of Minister Penk and other dignitaries affirms the essential role our members play in building the infrastructure New Zealand needs to thrive.
Many of the Association’s Life Members will be in attendance for this special celebration, offering a rare opportunity for the broader membership to connect with those who laid the foundations for our industry. Their presence is a powerful reminder of the value of long-standing commitment, and of how far we’ve come as an industry and as a professional community.
On the Saturday following the conference (19 July), Wellington will play host to a truly unique event: a Crane Parade down through the city. This family-friendly spectacle will bring cranes of all shapes and sizes into the public eye, showcasing their vital role in everyday life and in shaping the world around us. Designed with families and children in mind, the parade is a celebration of the strength, scale, and significance of cranes—not just as machines, but as symbols of progress and possibility.
The Crane Parade is a first-of-its-kind event in New Zealand, and one we hope will inspire a new generation to appreciate and perhaps even pursue careers in this essential field. It’s also a rare opportunity to engage the wider public in the work our industry does, and to shine a light on the men and women who operate, support, and service these machines behind the scenes.
We acknowledge that 2025 has brought challenges for many in our sector—tight budgets, project delays, and workforce shortages among them. But that’s exactly why coming together matters more than ever. This year’s conference isn’t just a celebration; it’s a chance to strengthen our collective voice, share solutions, and support each other. The crane industry has always risen to meet tough times with resilience and innovation, and this conference will be no exception.

I’m not a well-educated man, but i know there are so many different words used around safety in construction.
“Risk assessment, task analysis, job safety analysis, hazard identification, risk control.” all big, multiple syllable words, that I know have the same meaning, but it's confusing to have different terminology for the same thing.
Safety and hazard control doesn’t have to be hard. I want to make it as easy as possible for you so that you (and others) can be safe, competent and productive.
I’m going to use a hypothetical example of a task and give you a breakdown of how I see things.
“Weld a bracing bar mounting plate to an existing, in place steel beam at a height 4mtr from the floor”. That’s my task; clear to understand.
I have been very lucky in a contact allowing me to use the image of theirs to help with context and to be able to visualise the scenario.
My job site is a domestic airport terminal, third floor, section 'C'. Those I am working with and around know this site description.
Date and time: today, 11:30pm. My first reduction of potential harm and risk comes by starting work and the job after the terminal is closed – no public around.
What’s going to kill me or others doing this task?
• It’s up high, I could fall.
• It’s a non-ventilated area, the fumes from welding might get me
• There’s flammable material around me, it could catch on fire.
Let’s control those significant hazards:
1. Get a Mobile Elevating Work Platform, fit for the task and the environment. A scissorlift is the best choice here, giving me a good stable work platform whilst doing the welding, can position me perfectly and can even use the deck extension if I cant get the MEWP close enough to the wall. I can’t fall out as its just an up and down movement and the handrails are my fall protection, no need for a harness that might get damaged while I weld.
Also from being vigilant about the big things, I worked out I needed help with a spotter, and I needed lighting, hard hats and hi viz. All the smaller supporting risk controls came just from me looking out for the big things. You should also check and be aware that you have got everything.
• I need to ensure my MEWP training is up to date and I should practice the use of the MEWP to ensure I am competent in positioning it where it needs to go
• I do need to check the scissor lift can go in the lift and it can bear the weight, along with the floor it will be operated on. I’ll check with the project manager and get engineer approval
• I also need to keep other machinery away from my work area, I don’t want something hitting me and tipping me over whilst at height (exclusion area)
• I’ll also have to watch my head when going up in the scissor. I’ll “look up and live”.
2. Going to use a welding fume extractor c/w air scrubber. This will remove the fumes from the confined space area and the whole work section, protecting others. I will also wear my welding helmet integrated with a respirator (PAPR).
3. Let's surround the work area with welding blanket to protect adjacent construction materials from damage and catching fire while I weld. We will also have a fire extinguisher in the scissor platform and one on the ground by the spotter. I will also wear my welding protective gear.
Through controlling the three biggest things that could harm me I have controlled a lot more hazards – site tidiness (to get the MEWP in position), pedestrians (exclusion zone and working at a different time to others), weld splatter, burns, cuts, strains from reaching and so on.
Also from being vigilant about the big things, I worked out I needed help with a spotter, I needed lighting, hard hats and hi viz. All the smaller supporting risk controls came just from me looking out for the big things. You should also check and be aware that you have got everything.
Let’s record that and get sign off by those controlling me and then share it with everyone close to my work area.
“Record that” are key words, you need to be able to pass the right info on. This can be in writing or a recording that is easily shareable. If you struggle writing, try a different way of recording it like voice recording. Just be sure which ever way you do it is easy to use and understand.
I can crack on and do the job that I’m good at, knowing I have minimised the opportunity for things to kill me and I have looked after others too. That's the exact objective of the Health and Safety at Work Act.
Now, before those more intelligent than me and those that might like to show they are more attentive comment,
I admit this is just an example and may not cover everything. But if we can get the positive, engaging message out, get the basics happening and develop a positive culture to safety, we may just see better outcomes.
In summary, control the big stuff, the little stuff will either be resolved or become the big stuff once you rid the original big stuff. Record what you are doing and the hazards from doing the work. Include how you are controlling the hazards and share it with everyone around you. Get their buy in and support, be a safe, competent and productive worker.

The construction industry is famously tough, with its rigorous schedules and physical demands. Yet, while the physical risks are widely recognised, the mental health issues that construction workers face are less visible and often overlooked. Every week, nearly one worker dies by suicide, with men comprising 98% of these tragic losses. Addressing this serious issue, MATES In Construction has stepped up as a pivotal not-for-profit organisation.
The statistics are alarming. Construction workers are six times more likely to die from suicide than from a workplace accident. Factors such as job insecurity, high-pressure environments, and a culture that often discourages open discussions about mental health contribute to this heightened risk. Additionally, the Māori and Pasifika communities, which have a significant presence in the construction sector, have experienced increasing suicide rates, underscoring the need for culturally sensitive interventions.
MATES operates on the principle that suicide prevention is a collective responsibility. Their approach is multifaceted, focusing on building and strengthening workplace
communities to create environments that promote positive well-being. By engaging workers directly through on-site training and providing support to those identified as at risk, MATES ensures that help is both accessible and relevant.
To confront these challenges, MATES In Construction offers a variety of support and training programs designed to educate and aid workers in managing mental health issues effectively.
The General Awareness Training (GAT) is delivered to at least 80% of workers on a site, introducing them to the issue of suicide and equipping them with practical guidance on how to assist colleagues in distress. For those keen to take a more active role, the
MATES operates on the principle that suicide prevention is a collective responsibility. Their approach is multifaceted, focusing on building and strengthening workplace communities to create environments that promote positive well-being.
Connector Training prepares volunteers to identify signs of crisis and connect individuals to professional help. The Applied Suicide Intervention Skills Training (ASIST) equips individuals to develop safe plans for workers at critical risk, akin to having mental health first aiders on-site.
Beyond training, MATES offers case management support. Field officers, who have experience in the building and construction industry and are trained in suicide intervention, engage with workers on-site, providing a relatable and understanding presence. They connect at-risk individuals with appropriate professional services, ensuring a continuum of care that addresses both immediate and long-term needs.
Research and awareness
MATES is committed to informing the industry through research. By partnering with researchers, they delve into aspects of the construction industry that impact mental health and suicide risk. This evidence-based approach ensures that their programs are both effective and responsive to the evolving challenges faced by workers. Additionally, MATES raises awareness that mental health and suicide are industry issues that can be addressed collectively, creating a culture where open conversations are encouraged and stigma is reduced.
Creating resilient and stronger worksites is at the heart of MATES’ mission. By training and supporting workers and managers, they empower individuals to make a difference, not just within the confines of the construction site but extending into their everyday lives. This community-based
approach ensures that the impact of their initiatives resonates beyond the workplace, supporting a broader societal shift towards mental well-being.
The reach and impact of MATES are evident in the numbers and personal stories. Thousands of workers have been inducted, numerous Connectors trained, and countless training sessions delivered across Aotearoa. Personal testimonials highlight the profound difference MATES has made. One worker shared, “I was so alone, and at one stage, I was about to jump. Then I met the MATES fellas.” Another noted, “I never even thought of what some of my other brothers might be going through after this training, so now I’m determined to keep a look out for my mates.”
For those looking to support or become part of this transformative initiative, MATES offer various avenues. From becoming a Connector or ASIST-trained individual to partnering with MATES as an organisation, there are numerous ways to contribute. Fundraising and donations are also vital, ensuring that MATES can continue their essential work across the construction industry.
The construction industry in New Zealand faces a significant challenge concerning mental health and suicide prevention. However, with organisations like MATES in Construction leading the charge, there is hope. By creating a culture of openness, support, and community, we can work together to ensure that our mates are never left to face their struggles alone. After all, as MATES aptly puts it, “Stronger Together.”

Corrosion is the deterioration of a material through its reaction with the environment.
Conducting a root cause analysis to identify the exact cause of a failure of a material due to corrosion, and to determine appropriate remedies, requires a detailed and thorough analysis.
Failure analysis experts can be involved at any point of a product’s life cycle including the design, manufacturing, service, and ultimately, when a part of the product fails due to corrosion.
The types of corrosion damage that are encountered in service often include general surface corrosion, galvanic corrosion, and localised corrosion.
However, environment-related corrosion problems, that can be quite dangerous to a structure or product, include stress corrosion cracking, intergranular corrosion, selective leaching corrosion, and erosion corrosion.
The eight types of corrosion (Fontana) that commonly occur on structures and products made of different engineering materials are as follows:
• Uniform corrosion attack – this is the most common form of corrosion encountered.
• Galvanic corrosion – dissimilar metal corrosion.
• Crevice corrosion – an insidious form of localised corrosion.
• Pitting corrosion – a rapid form of
• Intergranular corrosion due to poor alloy metallurgy.
• Selective leaching corrosion – de-alloying.
• Erosion corrosion due to flowing fluids.
• Stress corrosion cracking (SCC). However, there are many less common
including high temperature corrosion; microbiologically influenced corrosion (MIC), hydrogen embrittlement, and corrosion fatigue.
This latter group of corrosion failure mechanisms often require very specialised knowledge to assess and solve them. Information sourced from:
In order to achieve a durable, highstrength, structural steel (weathering steel) in the unpainted condition, some requirements for designing, fabrication, construction, site climate conditions, inspection and maintenance need to be
Weathering steel, or to use its technical title of “structural steel with improved atmospheric corrosion resistance”, is a high-strength, low-alloy, structural steel.
In suitable environments, it can be used in an unpainted condition, which results in very low maintenance costs and an economic bridge solution.
The design of weathering steel bridges should be undertaken in accordance to the relevant parts of AS/NZS 5100.6. However, there are several requirements – mostly related to detailing and suitability of environment, which relate specifically to weathering steel, which are outlined in this publication.
This steel design guide for bridges in New Zealand was prepared to provide guidance to industry on the required aspects of site suitability, design, fabrication, construction, inspection and maintenance for the appropriate use of weathering steel in bridges in New Zealand.
‘Weathering steel’ is a high-strength, low-alloy, structural steel that, in suitable environments, can be used in the unpainted condition.

Weathering steel develops a tightly adherent rust layer or ‘patina’, which significantly retards the corrosion rate of weathering steel compared with conventional structural steel, while also providing a versatile high strength structural steel.
However, to realise the full capability of weathering steel in bridges requires attention to some aspects of the design, fabrication and construction of the
bridge and the consideration of the climatic conditions at the site.
With attention to these details, bridge life spans of a 100 years, or more, can be accommodated with weathering steel.

Demolition work often hides a silent menace – asbestos. Once celebrated for its fireproofing and insulation qualities, this fibrous mineral is now known to be a dangerous carcinogen. Breathing in asbestos fibres can lead to severe, life-threatening diseases, underscoring the importance of safe and compliant demolition practices.
The risks are inherent in the very nature of demolition. The process of dismantling a structure inevitably disrupts and breaks materials apart. If these materials contain asbestos, the demolition process releases microscopic fibres into the air. These fibres are invisible but pose a significant health threat. When inhaled, they can settle deep in the lungs, causing damage that may take decades to appear.
The impact of asbestos exposure is serious, with diseases taking 10 to 40 years to develop after initial exposure. This lengthy latency period can lead victims to feel secure, only to face severe health issues many years later.
The dangers of asbestos are not confined to demolition workers alone. Airborne fibres can
travel far beyond the demolition site, risking the health of nearby residents, bystanders, and even family members who come into contact with contaminated clothing.
Fortunately, stringent regulations and safety measures help mitigate these risks in demolition projects. Ensuring safety begins with the expertise of trained asbestos removalists, who are skilled in identifying asbestoscontaining materials (ACMs) within buildings.
The New Zealand Demolition Asbestos Association (NZDAA) plays an essential role in advocating for safe industry practices. Its website (www.nzdaa.com) offers
important resources for both contractors and homeowners.
The removal of asbestos is a highly specialised task carried out by trained professionals who wear protective gear, such as respirators, to avoid inhaling dangerous fibres. The removal process involves strict containment measures, such as sealing off the work area with plastic sheeting and using negative pressure systems to direct contaminated air through a filtration system.
Once the asbestos has been safely removed, a qualified inspector issues a clearance

certificate, confirming that the area is free from asbestos and suitable for further demolition work.
The dangers of asbestos in demolition are profound. Exposure to these fibres can have irreversible health consequences.
By following rigorous safety protocols, employing certified asbestos removal experts, and adhering to regulations, we can ensure demolition projects are conducted safely, protecting both workers and the surrounding community.
