What are National Multiple-Use Approvals?
The Building System Assurance Team of Marketing Services (MBIE) can issue National Multiple-Use Approvals (NMUAs) to volume builders for building designs that will be replicated several times in any district, regionally or nationally. The benefit of NMUAs is that MBIE can ‘pre-approved’ these building designs for Building Code compliance. Such an approval is issued in the form of a Multi-Proof statement. See Building Act 2004, sections 30A – 30H and MBIE guidance.
A Multi-proof is a statement issued by MBIE that confirms that a specific set of building plans and specifications complies with the New Zealand Building Code. A Multi-proof statement is not, and does not replace a Building Consent. The holder of a Multi-proof must apply to the relevant Building Consent Authority (your local Council) for a Building Consent each time they wish to construct the design to which the Multi-proof statement relates. The Council has 10 working days to process the application.
How to apply for a Building Consent that has a Multi-proof statement
- Follow the process for a normal building consent set out on Applying for a Building Consent and put together the required documentation.
- A completed copy of the Building Consent Application Form (Form2), including the project value for the whole project, not just the site-specific portion.
- A copy of the Multi-proof certificate, which will show any applicable conditions.
- A statement addressed to the BCA (your local Council) stating that the design for which the Building Consent is being sought:
- Complies with the approval issued by MBIE, and
- Meets all the conditions of the Multi-proof (such as wind and snow loading restrictions) for the proposed site.
- A complete copy of the plans and specifications to which the approval relates. These will bear MBIE’s approval mark and will include any relevant approved customisations.
- Full details of any site-specific features proposed for the building such as a site drainage plan or site-specific foundation details.
- Any technical information, calculations, and design Producer Statements or other evidence needed to establish the Building Code compliance of the building’s site-specific features (if applicable).
- Application fees and charges.
MBIE has published further information about NMUAs on their website, including the benefits, which are eligible, how to apply and the assessment process. The MBIE Multi-proof register is also available.
