MultiProof

MultiProof standardised building designs.From 1 February 2010, volume builders can obtain a MultiProof or National Multiple-Use Approval for standardised building designs that are intended to be replicated several times.

MultiProof approvals are issued by the National Multiple-Use Approval Service of the Department of Building and Housing.

A MultiProof is a statement by the Department that a specific set of building plans and specifications complies with the New Zealand Building Code. Under the Building Act 2004 (as amended in 2009), Building Consent Authorities (BCAs) must accept a MultiProof as evidence of Building Code compliance. 

MultiProof approvals will create time and cost savings for volume builders by removing the need for the same or substantially similar building designs to be assessed repeatedly by individual building consent authorities for Building Code compliance.

A building consent will still be needed. The Building Consent Authority’s (BCA) role will be to:

  • approve site-specific details, including foundations and utilities
  • ensure that any MultiProof conditions have been met, and
  • undertake normal inspections during construction.
