Give feedback on the Building Product Specifications – Version 2

About the consultation

In April 2025, the Building (Overseas Building Products, Standards, and Certification Schemes) Amendment Act 2025 was passed, which amends the Building Act 2004 to reduce barriers for using high-quality building products imported from overseas.

Now that the law has passed, MBIE has implemented new pathways to make it easier to use quality overseas building products in Aotearoa New Zealand. One of these new pathways is the Building Product Specifications.

How the Building Product Specifications make it easier to use overseas products

The Building Products Specifications:

• provides more choice of building products for use in Building Code compliant work
• incorporates a wider range of New Zealand and international standards into building compliance pathways (acceptable solutions and verification methods)
• makes it easier and faster to add, update and modify building product standards in the Building Code system.

The Building Product Specifications can only be used to demonstrate Building Code compliance when referenced by an acceptable solution or verification method.

The first edition of the Building Product Specifications was published on 28 July 2025. It contains specifications and standards for products that we already know and use, such as windows, timber and cladding.

Version 2 of the Building Product Specifications

The Building Product Specifications is a living document and will incorporate new or updated standards when they are identified as providing an equivalent or better level of performance.

A draft of Version 2 of the Building Product Specifications contains additional standards and specifications for:

• timber, including wall bracing elements
• sound insulation
• heating, ventilation and air conditioning
• closures including fire doors, smoke control doors, glazing, and dampers.

How your feedback helps

Your feedback will help MBIE know:

• whether you agree that the standards and other references proposed to be cited in Version 2 of the Building Product Specifications are appropriate for use in Aotearoa New Zealand, and
• if there are further additional standards or reference documents you would like to be considered for the next edition of the Building Product Specifications, which will be developed for consultation later this year.
