If you are considering importing, supplying or manufacturing a building product, our information on product assurance and certification schemes can help you understand how to comply with our building laws.

MBIE provides information about product assurance for importers, suppliers or manufacturers of building products or systems, product certification (CodeMark), the modular component manufacturing scheme (BuiltReady), and the multiple-use approval scheme (MultiProof).

Building product assurance

If you make, import or supply building products or systems, it is your responsibility to make sure they are fit for their purpose and for use in the New Zealand market.

There are a number of ways to show your product or system complies with the Building Code. The cost of each option will also depend on your product or system.

There are minimum information requirements for building products in Aotearoa New Zealand which apply to designated building products manufactured in, or imported into, Aotearoa New Zealand. These regulations were made by the government in June 2022, giving the sector an 18-month transition period to prepare to comply with these changes. The changes commence and are enforceable on the 11th of December 2023.

Certification schemes

How the three schemes work together

Video transcript

MBIE administers three voluntary certification schemes in Aotearoa New Zealand.


CodeMark is a voluntary product certification scheme that is an unchallengeable form of product assurance. Building consent authorities must accept a CodeMark certificate as evidence of compliance with the Building Code, as long as the product is used in accordance with the use and limitations defined on the certificate.

BuiltReady is a voluntary certification scheme for manufacturers of modular components. Manufacturers who meet robust quality standards and criteria can apply for certification under the BuiltReady scheme. Building consent authorities must accept a manufacturer's certificate as evidence of that modular component's compliance with the Building Code.

If you want to build the same or similar building design many times, you could consider applying for a MultiProof approval. Find out how this national multiple-use approval scheme works, how to apply, and what you need to provide to show a set of standardised plans and specifications complies with the Building Code.
