In 2024, the New Zealand government introduced the Building (Overseas Building Products, Standards, and Certification Schemes) Amendment Bill to increase competition in the supply of building materials and reduce construction costs. The Bill, which has been referred to New Zealand Parliament’s Select Committee, will allow building products certified under recognised overseas standards or certification schemes to be used in compliance with the New Zealand Building Code.

While the legislation does not specifically mention steel, the potential implications for the industry are significant. Structural and reinforcing steel are cornerstone materials in construction, and their compliance with stringent New Zealand-specific requirements, particularly in seismic performance and long-term durability, is essential.

New Zealand's unique geological conditions, including high seismic activity, demand construction materials that meet rigorous standards for tensile strength, yield strength, and ductility. Steel from overseas may conform to international standards but could fall outside the narrow performance bands required to ensure structural safety in New Zealand. Variations in upper and lower tensile or yield strengths, while permissible under some international standards, could result in performance gaps that weaken building resilience during seismic events.

The introduction of this Bill highlights the need for careful scrutiny in determining the suitability of materials entering the New Zealand market. ACRS-certified steel has long served as a benchmark, ensuring not only compliance with local and Australian standards but also providing essential independent verification, traceability and quality assurance.

As the legislative framework evolves, the importance of retaining robust oversight in material certification and ensuring compliance with New Zealand’s unique performance requirements cannot be overstated. ACRS remains committed to supporting the industry by maintaining the integrity of the supply chain and promoting rigorous standards to safeguard New Zealand’s build environment.
