What is Multiple-use Approval (MultiProof)?
The MultiProof scheme is beneficial for builders and companies who build standardised designs. It provides evidence of compliance for Building Consent Authorities (BCAs), and is a statement by the Ministry of Business, Innovation and Employment (MBIE) that a set of building plans and specifications for a building complies with the Building Code.
To be eligible for MultiProof, you must have the intention and the ability to build an approved design at least 10 times over two years. MultiProof speeds up the consenting process. It does not give the right to carry out building work that requires a building consent. You still need to apply for consent each time you want to build.
MultiProof establishes that a design complies with New Zealand Building Code.
Do I still need a building consent if I have a national multiple-use approval?
Yes. National multiple-use approvals are issued by the MBIE.
A MultiProof is a statement by the Ministry that a specific set of building plans and specifications complies with the New Zealand Building Code. Under the Building Act 2004, Building Consent Authorities (BCAs) must accept a MultiProof or national multiple-use approval as evidence of Building Code compliance. However, a building consent is required each time you want to build a design that has been issued with a national multiple-use approval.
How long does the application take?
If your building consent application includes a MultiProof, the BCA must grant or refuse it within 10 working days instead of the usual 20 working days.
When receiving a building consent application that relies on a MultiProof, the BCA will undertake the following:
- check the application is complete, based on the list provided on the previous page of this document
- ensure the application is within the terms of the MultiProof and that the approval is current
- assess the Building Code compliance of any building features not covered by the MultiProof (for example, site-specific features, such as drainage)
- check that the Memoranda (‘Approval/s’ of design work) for the site-specific RBW include all the necessary information
- ensure that the proposed site meets the conditions of the MultiProof (such as wind or climate zone limitations)
- ensure any other approval conditions are met
- grant or refuse the building consent within 10 working days
- advise the applicant, in the building consent, of inspection requirements and any documentation that must be supplied before the code compliance certificate will be issued, such as an energy work certificate and Memoranda (Records of Building Work or RBW) from the trade LBPs involved in the construction of RBW.
Similar to a building consent, the BCA may need to contact you with a request for further information (RFI) on aspects of your application during processing.
If this is the case, the BCA will ‘stop the statutory time clock’ and will not continue processing your application until we receive the requested additional information. When the requested information is received, the BCA will ‘restart the statutory time clock’ and continue processing your application.
When we have finished processing your application, you will be notified of the outcome including confirmation of the building consent being issued.
Built Ready Scheme
BuiltReady is a voluntary certification scheme for manufacturers of modular components.
It allows registered manufacturers to issue certificates covering the manufacture, or design and manufacture, of modular components. Certificates will need to be included in the building consent and code compliance certificate (CCC) applications. The modular components that have certificates that are issued by a design and manufacture registered manufacturer will be ‘deemed to comply’ and the certificates must be accepted by the BCA as evidence of compliance with the Building Code.
The BCA will;
1. ensure the manufacturer supplying the certificates that accompany a building consent or CCC application have a current registration within the scheme.
2. Check that the modular component is used in accordance with the scope and limitations as defined on the certificate, and
3. Need to establish the extent of any work not covered by a manufacturer's certificate.
CodeMark
CodeMark is a voluntary product certification scheme that provides an easily-understood and robust way to show a building product or building method meets the requirements of the New Zealand Building Code.
A CodeMark certificate must be accepted by the BCA as meeting the requirements of the New Zealand Building Code, provided the certificate is current and the product or method is used in accordance with details noted on the certificate.
There is a mandated certificate template for CodeMark certificates that certification bodies must use when issuing certificates.
Effective 11th December 2023, new CodeMark scheme rules 4.4 and 4.5 relating to public disclosure requirements commence. Under this new rule, certificate holders are required to make information such as design or installation manuals accessible on their website or via request on their website. There are instances when a certificate holder may reject a request for this information, such as if the product requires an approved installer and the person requesting is not approved to install the product. Information such as test reports and opinions are not required to be disclosed.
