MultiProof application assessment process

Last updated: 21 March 2016

Your MultiProof application will be assessed for its Building Code compliance. If it is approved, it will be listed in the MultiProof public register.

Before we formally accept your MultiProof application, we will check to make sure it:

  • is eligible for assessment
  • includes all the required information
  • includes your application pre-payment.

We will let you know if we accept your application for assessment. From there, we still start checking your design for Building Code compliance.

How the process works

We have up to 40 working days from the date of formal acceptance to either approve or decline your MultiProof application. We may be able to process a well prepared and comprehensive application in a shorter timeframe.

We may need to contact you for further information or clarification on aspects of your application during the assessment process.

If this is the case, we may ‘stop the clock’ and not continue processing your application until we receive your additional information. When we receive the information, we will ‘restart the clock’ and continue assessing your application.

When we have finished assessing your application, we will let you know our decision in writing. We will also include an invoice for any outstanding amount for processing your application.

If your application is approved

We will issue your MultiProof certificate if your application is assessed as complying with the Building Code and you have paid all outstanding fees.

The certificate covers the designs and any alternatives included in your application. The alternatives will be listed on the back of the certificate as ‘permitted variations’. It will also list any specific conditions that apply to your MultiProof.

If you have amended your plans and specification during the assessment process, you will be asked to provide an updated document index and design and options summary. You will also need to provide an amended set of specifications.

The MultiProof register

Your approved MultiProof will be listed on MBIE’s online register. The register records the names and contact details of each approval holder, as well as a name and brief description of each approved design.

Public access is also provided to your MultiProof certificate, and can be provided to the design and options summary and document index.

MultiProof register

Building control officials will need a RealMe® login and to request an invite from multiproof@mbie.govt.nz to access the MultiProof Shared Workspace.

MultiProof register

A copy of your approved MultiProof will be held separately on a secure website. This will include a copy of:

  • the approved plans and specifications
  • the MultiProof certificate
  • the design and options summary
  • the document index.

If your MultiProof allows for parameter based variations it will also include the approved means of compliance.

All intellectual property in the plans and specifications available in the MultiProof database remains with the owner of those plans and specifications.

You will need to advise us if another party has been authorised to use your MultiProof.

MultiProofs are valid indefinitely

Your MultiProof will be valid indefinitely unless:

  • the Building Code changes to the extent that building work properly completed in accordance with the approval will no longer comply
  • the approval no longer meets the prescribed eligibility criteria
  • or the approval was obtained by fraud, misrepresentation or concealment of the facts.

We will write to you if the Building Code changes in a way that affects your MultiProof. We may ask you, if necessary, to apply for an amendment to your MultiProof that takes account of the changes.

We encourage MultiProof holders to review their approved plans and specifications from time to time and consider if they require any amendments. For example:

  • modify the design
  • increase the permitted variations
  • clarify any issues raised during the construction or consenting process
  • update the specification.

This is to enable us to update the MultiProof register.

If your application is declined

We may decline your MultiProof application if:

  • your design is assessed as being non-compliant with the Building Code
  • it includes a banned method or product
  • you have not paid the required application fee
  • or you have not supplied information we may have asked for within a reasonable time period.

If we decline your application we will charge fees for all costs incurred up until that time.

You are able to appeal to the District Court if we decline your application and you disagree with the outcome.

Withdrawing your application

You can withdraw your application at any time by giving us written notice. You will be charged for any costs incurred in processing the application up to the time of withdrawal.

If these costs are greater than the application pre-payment we hold, we will invoice you for the outstanding amount.

If they are less, we will refund the unspent portion minus the non-refundable component of $511.11 (including GST).
