Product assurance and certification schemes
Last updated: 29 August 2025
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.
The Ministry of Business, Innovation and Employment (MBIE) provides information about product assurance for importers, suppliers or manufacturers of building products or systems, including product certification, 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 Aotearoa 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 commenced and were enforceable on 11 December 2023.

Certification schemes
How the three schemes work together
MBIE administers three voluntary certification schemes in Aotearoa New Zealand.
CodeMark
CodeMark is a voluntary product certification scheme that is an unchallengeable form of product assurance.
Building consent authorities (BCAs) 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
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.
BCAs must accept a manufacturer's certificate as evidence of that modular component's compliance with the Building Code.

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

Approved Products Certified Overseas
If a product has an overseas product certification recognised by MBIE, that product will be deemed to comply with the Building Code.
BCAs must accept a recognition notice as evidence of that product’s compliance, provided it is used as intended including any conditions or limitations of recognition.
