BRANZ’S E-Learning Modules

One of NASH’s E-learning initiatives is now available as featured in the NASH Winter newsletter. 

NASH recognised the limited educational resources available to residential designers covering steel-framed housing. BRANZ who have produced the Building Basics – Lightweight Steel Framing guide proposed developing an on-line learning resource to address the knowledge gap. Thanks to our NASH members for their contribution and to BRANZ for their expertise.

This series of three modules provides a practical and comprehensive introduction to the design and construction of lightweight steel-framed buildings. Developed by BRANZ in collaboration with the NASH, the modules are aimed at designers and builders seeking to gain skills and knowledge on this topic.

TOPIC 1.  Steel-Framed Buildings – An overview for designers and builders
This 20-minute module steps designers and builders through the basics of steel-frame buildings. By completing these building blocks, you will gain an understanding of statutory requirements; materials and specifications; linings, thermal breaks, and insulation; and floors, roofs, and walls.  Learn more

TOPIC 2.  Steel-Framed Buildings – Understanding the principles of design
This 20-minute module gives designers in-depth, practical guidance on design principles and considerations for lightweight steel framing that differ from timber construction. This module includes preplanning; steel basics; fixings and connections; and on-site remediation.  Learn more

Newsletter Issue 1, January 2022

Welcome to 2022

2022 promises to be a busy year for NASH and the residential sector. With residential consents at all time high, government committed to building more social and emergency housing all at a time when traditional framing materials are in scarce supply and with significant cost increases. The timber shortage will be with us for some time, as it is a global issue and exacerbated here in New Zealand owing to significant log exports to China. If material supply and running a business amid COVID restrictions wasn’t enough of a challenge for the residential sector there is more change ahead. New H1 requirements
come into force in November 2022. MBIE’s Building for Climate Change programme will require all of us to better understand how our building products contribute to the embodied and operational carbon in new houses and what we as manufacturers are doing to reduce the impact. The Commerce Commission launched an enquiry into the building supplies market and no doubt some of you will be contacted.
Managing through these turbulent times is why we need a strong and active member organization representing our interests. The NASH team currently have a large programme of work to address current and future challenges which include
  • Seismic bracing R & D programme in partnership with University of Auckland and Alrite Steel.
  • Producing a Best Practice Design Guide for Light Steel frame to compliment NASH Standards – our thanks to New Zealand Steel for funding / hosting an intern to deliver this work.
  • Developing an R & D programme to deliver to MBIE’s H1 – Energy Efficiency Code changes.
  • Working with Councils to develop a simple process for product substitution when builders are held up though lack of supply. Our thanks to Rodney and EQ Struct for developing a simple and robust process to support Council. This will be trialed in February.
  • Upgrading the NASH website with user friendly portal to provide easy access for members to technical literature and R & D learnings. Again our thanks to New Zealand Steel for providing support funding this upgrade.
In addition the NASH team are focused on QA process / audit for members and working with the Sustainable Steel Council to assist NASH members to sign up to and audited against the Sustainable Steel Charter. All of the above would not be possible without member contributions and the support of NASH’s major partners – so thanks for your ongoing support.

NASH would like to thank our sponsors and industry partners for their continued support.

Getting to know NASH members – Pawel Milewski from ExtraMile 

Who are ExtraMile?
ExtraMile is an independent structural engineering practice in Hawkes Bay. We pride ourselves for our emphasis on innovative and exotic designs backed by our experience of numerous building materials and construction techniques – from traditional to cutting edge innovation. We primarily work on unique small projects locally, while also working all over New Zealand and internationally.
How did ExtraMile get involved with NASH?
We have been experts in light gauge steel framing for a long time, having worked with it in the UK before moving to NZ. We were able to bring our expertise and contribute to LGSF’s use here, and subsequently got involved in NASH.
What is a project that ExtraMile is particularly proud of?

We are proud of how we managed to utilise the advantages of light-gauge steel framing (LSF) to design an innovative apartment building on Regent Street in Auckland. This building was unique in how it had a completely modular design, where an offsite factory assembled 9 volumetric modular units. These were fully finished with walls and services such as water and electricity. Then, they were simply stacked on site like boxes. The finished project marked one of the first practical modular buildings in New Zealand, while also significantly reducing the cost of the building and shortening its assembly time on site. We are proud of how this project leads the way in making construction a more streamlined and affordable process using new technology.

What brings you satisfaction in your job?

I am always excited to come up with and see clever, innovative solutions being used in the construction process. I get out of bed in the morning as I am excited about the future of construction technology, and am eagerly waiting for the way we build things to change from how it was done x years ago, as little has changed since then. I get the greatest satisfaction when my work contributes to a fundamental change in what is possible in construction.

How did you get involved with steel framing?

My experience with LSF comes from work in Ireland and the UK after I moved there from Poland. There LSF was also a new technology, and I worked with the BRE (UK equivalent of BRANZ) to certify the LSF building method. The company I worked with was the second ever to receive certification to work with LGSF. There I helped use the technology to build a good amount of multi-storey buildings. After moving to New Zealand I am working with LSF in my own company, upholding the innovation in the technology on a slightly smaller scale here.

What challenges are you facing in your job?

I am interested in using innovative technology like LSF to boost construction possibilities. Unfortunately, getting some of my colleagues to have the same will to use these lesser proven, new methods has not always been easy. The fact that building technology has not progressed much in x years has something to do with how common to just want to build things the old way. It is an ongoing challenge for me to work with LSF at scale. I try to overcome this by always making my LSF designs as well designed as possible, and set the precedent that innovation like this is truly worthwhile and beneficial to construction. I am seeing it slowly get embraced and look forward to help contribute to where LSF can get to in the future.  I am surprised by how strong small amounts of LSF steel can be as long as it is designed and detailed correctly.

What do you do outside of you work life, is there anything on your bucket list?
One of the reasons I moved to New Zealand originally was to enjoy the beautiful nature here. I enjoy hiking and seeing untouched scenery and would love to walk the Te Araroa Trail at some point. I have been training Karate as sport since I came to NZ, and have managed to reach a Black Belt grade last year. As someone who designs static things that stay on the ground, I also enjoy the idea of flying. In my free time, I like to go paragliding.

MBIE – New tiny house guidance released

New tiny house guidance has been developed around what rules apply and what requirements to consider before building a tiny house.

Tiny houses need to be safe, healthy and durable for their intended use. As building regulator, MBIE aims to ensure that all building work in New Zealand meets these requirements.

This guidance seeks to clarify any ambiguity on which rules apply to which tiny houses, particularly for tiny houses on wheels. Tiny houses on wheels will often be vehicles (eg motor homes) but will also be buildings if they are ‘immovable’ and ‘occupied by people on a permanent or long term basis’. Read more



Product Substitution Guidance

MBIE has put out a guide that will assist designers, builders and home owner who are considering different products to those specified or requested. See Product Substitution Guidance.

National Construction Pipeline Report

Infinite recyclability is one of the key aspects underpinning the sustainability message of steel.

HERA Report R5-89 Steel Recycling Report shows steel plays a key role in the circular economy

Undertaken by thinkstepANZ it showed an impressive 72% of steel scrap in New Zealand is recycled, and that recycling steel scrap produced in Aotearoa New Zealand provides significant environmental benefits – despite the need for transport to overseas recycling facilities.

The study also showed that the amount of steel scrap collected for recovery is critical to the overall benefits of the recycling system.  Read more


Ngā Kāinga Anamata – Homes of the Future

Ngā Kāinga Anamata is a sustainability-innovation public housing pilot project, aimed at driving carbon emission reduction in New Zealand’s construction industry.



The project was gifted its name, meaning ‘homes of the future’ to reflect its aspiration of building tomorrow’s houses today, while maintaining a cultural lens and links to core Māori values.

The core focus of Ngā Kāinga Anamata is to achieve the Government’s 2030 carbon emission targets by 2024, sharing insights and influencing change in New Zealand’s built environment.

The project will deliver 30 new homes within five, three-level apartment buildings in Auckland’s Glendowie. Each near identical building will use a different construction technology, enabling sustainability insights to be gathered on a range of building materials and systems.

Council issues warning to tradies as list of building materials expanded

Auckland builders have an expanded list of materials they can substitute to cope with the supply crunch caused by Covid-19.

But the council is warning tradies to do their homework and check in with it early on.

Supply shortages have been forcing more and more tradies to ask councils if they can swap out specified products if they cannot get them.

Auckland Council has now expanded its scope to allow for swaps of:

• timber framing to steel framing
• metal roofing to concrete tiles, or vice versa
• some cladding types

There is no timber first-policy.


There is no ‘timber-first’ policy. There is a policy to reduce the carbon impact of government buildings.

This is Minister for Economic Development, Government Procurement and Forestry Hon. Stuart Nash’s response to written parliamentary questions from Opposition spokesperson for Construction Tim van de Molen, inquiring into the government’s timber-first policy in June 2021.

The minister and his predecessor have been subjected to significant lobbying by sector players to adopt a timber-first policy for the procurement of government buildings. The minister was right not to yield to pressure.

In a comment piece which ran in the National Business Review on 17 July, Metals outlines why Nash was right to reject a ‘wood-first’ policy.

This includes the fact that New Zealand’s Building Code and government procurement are material agnostic, focused on delivering resilient and high-performing buildings.  Decisions with respect to which material is used in what building needs to be left to architects and engineers based on independent robust data, informed by International Standards and New Zealand’s specific seismic/climatic challenges.

Building Code changes drives warmer, drier, environmentally friendly homes

Every year MBIE consults on the Building Code. This year’s proposed changes aim to make homes and buildings warmer, drier and healthier, with less impact on our environment, while also bringing New Zealand more in line with international standards.

Metals New Zealand in partnership with the National Association of Steel Framed Housing Inc (NASH) has submitted on the proposed changes, which are long overdue. Read our submission here Metals New Zealand NASH submission-form-building-code-consultation-2021 final.

Overall, we support the direction. The proposed changes are significant and coupled with the Building for Climate Change programme, the sector will need time to design and test solutions to deliver to increased performance requirements and international standards.

Then there will need to be learning programmes for designers, engineers and subtrades to ensure new solutions are designed and installed appropriately.

Alongside pointing out some gaps in the proposed changes regarding energy efficiency, the bigger area of concern for us with the discussion document is lack of engagement on and funding for Standards.

The performance and resilience of New Zealand’s built environment is dependent upon Standards. But, since they were absorbed into MBIE there has been intermittent dialogue with the sector as to funding Standards, a programme of work and Joint Australia/ New Zealand Standards – at a time when the accumulated funds in Building Levy have been significant.

The effective decoupling of join AS/NZ standards due to MBIE’s unwillingness to fund contributions has created a trade barrier, increased risk and resulted in loss of business for New Zealand manufacturers.

We point out that NASH has funded its own technical solutions and met the costs of developing Acceptable Solutions.   When NASH Standard Part b 2019 and NASH Building Envelope Solutions 2019 were cited as Acceptable Solutions under the Building Code, MBIE insisted that NASH technical documentation should be available free of charge to the sector.

The costs of preparing / maintaining this documentation are met by NASH members who effectively are paying for technical support for the sector, (both members and non-members who build in light steel framing) – hardly a fair, equitable or sustainable funding model moving forwards.

Given that some of our past building solutions are currently constrained by material supply, NASH asks the question as to why MBIE should not be funding Standards for light steel framing and other 21st century solutions to New Zealand’s building needs?

What was the Minister thinking?

The following opinion piece by Metals CEO Nick Collins appeared in NBR-15 June

Making Sense of Wood First  

Minister Nash – what were you thinking?

On Friday 10 June, Forestry Minister Stuart Nash announced a timber first strategy for government buildings – stating that “there is nothing you can do with steel and concrete that you can’t do with timber”.

Is the Minister proposing that the new pedestrian / cycling bridge over Auckland harbour will be built from timber?

Embracing light steel framing as alternative to timber

Uncertainty around timber supply for residential construction shows how the fortunes and future of New Zealand’s construction and manufacturing sectors are inextricably linked.

Our residential construction supply chains are not resilient, with an over reliance on one material. Firstly, there are credible and cost-effective alternatives to timber. Light steel frame construction has been available in New Zealand for over 30 years as a viable alternative to light timber frame construction in one to two story housing. Read more

Supply chain performance in CFS house-building*

Prefabrication is gaining greater traction because of its potential to address New Zealand’s housing problem with cost-effective, rapid construction and quality solutions. This has placed huge responsibility on producers (supply chains) as the flagbearers of innovation in construction. However, most of the small and medium sized producers, irrespective to their involvement in the offsite work, are facing critical challenges to remain in this competitive business. 

A list of critical factors was compiled based on the opinion of prefab experts for performance of suppliers in prefabricated house-building (from manufacturer to builders). Later a survey was conducted (pre-COVID), with suppliers of CFS building products (framing to volumetric), to determine the criticality level of performance challenges at company level. This study provides an insight of the CFS industry and vary based on the organizational maturity, supply chain roles and business scope. Also, it is helpful for both existing and prospective suppliers of CFS products, to understand the business dynamics.

*These findings are taken from PhD research project of Mr. Rehan Masood under supervision of Dr. James Lim, from Department of Civil & Environmental Engineering, The University of Auckland, Auckland (




Steel Framing Presentation at UNITEC in Lockdown Level 3

One of the skills that lockdown has taught us to embrace is using technology and the level 3 lockdown in Auckland meant the steel framing presentation to the Architectural Technology student had to be held via a Zoom session. Over 150 students attended the virtual session, it was the largest presentation on steel framing that NASH have given.

The presentation was planned for 3 hours, but over ran by 15 minutes. There were questions at regular intervals throughout the sessions from the students.

The presenters were Alistair Fleming from NASH providing an introduction to steel production and applications.

Daniel Spencer from Framecad gave an in depth presentation on designing with light steel framing and examples of buildings under construction.

Bruce Campbell who is an Architectural Designer who has designed a number of steel framed houses and had a couple steel framed houses built for his own use.

Steve Tsai the lecturer who arranged the session was pleased with the presentation.

We are now looking to next year to improve the coverage and activities for steel framing at UNITEC.

Cold Formed Steel Design Seminar Feb 2020

Cold-formed steel is one of the most vibrant and exciting developments in steel construction, with New Zealand and Australia being amongst the world leading countries in this form of construction. Cold-formed steel is used in New Zealand for portal frame structures, houses and medium rise buildings. The design of cold-formed steel is completely different than hot-rolled steel due to thin section thicknesses and the associated need to consider buckling behaviour.


• Direct Strength Method provided by AS/NZS4600 needs engineering judgments on the buckling behaviour of the elements that will be introduced and discussed in this seminar.
• Direct Strength Method demands computer modelling in THINWALL, CUFSM, or other finite strip method software which will be covered in this seminar.
• There will be worked examples presented during the seminar such that participants will be prepared to use Effective Width method and Direct Strength method with more confidence as soon as they get back to their office.
• Connection designs and their concepts will be discussed in the portal frame and building designs which are useful for practicing engineers.
• New findings in the area of cold formed steel designs will be introduced and discussed.

Seminars are being held all over NZ!
