The MultiProof scheme is beneficial for builders and companies who build standardised designs. It provides evidence of compliance for Building Consent Authorities


Multiproof is a statement by the Ministry of Business, Innovation and Employment (MBIE) that a set of plans and specifications for a building complies with the Building Code.

To be eligible 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.

How MultiProof works

MultiProof establishes that a design complies with NZ Building Code.

When your building consent application includes a MultiProof the BCA must grant or refuse it within 10 working days instead of the usual 20.

The Building Consent Authority (BCA) confirms and establishes:

  • the design, with any permitted variations, is the same as the design approved in the MultiProof
  • the proposed site meets the conditions of the MultiProof
  • the site specific features of the design comply with the Building Code
  • the inspections required.

Who should use MultiProof

MultiProof is beneficial for those who:

  • build or intend to build a number of similar designs
  • use standard construction details for a range of similar buildings
  • want to save time when applying for a building consent
  • need consistency when applying for building consents to different BCAs
  • can build the approved design at least 10 times in a two year period.

To apply for MultiProof, your design will need to meet certain requirements.
