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?
Prefabricated Steel Panels Boost Quality and Construction Speed for Church and Retirement Community Projects
Two projects, a Latter-day Saints church in Australia and a retirement community in Canada, show how prefabricated cold-formed steel (CFS) wall and roof truss systems help ensure straight and accurate construction and improved construction schedules versus wood framing and concrete framing alternatives.
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.

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.
Wintec’s Carpentary Students discover the benefits of Light Steel Framing
Rollforming Services (RFS) and Central Steel Framing (CSF) teamed up to help Wintec’s (Waikato Institute of Technology) carpentry apprentice students learn how to assemble steel frame walls. Students discovered the benefits of steel framing and the experience opened their eyes to the possibility of working with steel framing in the future. See more
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.
THIS SEMINAR WILL COVER:
• 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!
