Recognition notices for Approved Products Certified Overseas

A recognition notice shows which building products the Ministry of Business, Innovation and Employment (MBIE) recognises under the Approved Products Certified Overseas pathway.

How to use a recognition notice in a building consent application

Here are the steps to using Approved Products Certified Overseas recognition notices as part of a building consent application:

Step 1. Decide on what recognition notice you are going to use in your building consent application.

• Make sure the recognition notice lists the product certificate you are specifying in your building consent application.
• Recognition notices and product details are under the heading current recognition notices.

Step 2. Add the recognition notice and supporting information into your building consent application.

What you need to include in your application is:

• a copy of the recognition notice
• the product certificate for that recognised product
• relevant supporting technical information such as installation manuals.

Product certificates should be accessible either on the product certification scheme’s website or on the product certification body’s website.

The recognition notice shows certain product certificate details, including the responsible product certification body, the certificate number, and the conditions and limitations of how you must use the notice.

Step 3. Process your building consent application

The building consent authority (BCA) processes your building consent application with the recognition notice as evidence of compliance with the Building Code. If specified as laid out in the recognition notice, BCAs must accept the recognised building product.

Approved Products Certified Overseas is a deemed to comply pathway. When the BCA receives a building consent application, they will follow this process to establish compliance:

• Check that the recognition notice is current. Each recognition notice has a unique ID to make it is easy to find the right one on this page.
• Check that the product certificate is the same one stated on the recognition notice, and the product certificate is current. Product certificates should be accessible either on the product certification scheme’s website, or on the product certification body’s website. If the product certificate is not available on their website, BCAs will email the relevant product certification body.
• Check that the product is specified in accordance with its intended use. The intended use should be specified on the product certificate, but it also may be in other supporting technical information. For recognised WaterMark certified products, the certified intended use and scope, and application of the product can be found on the recognition notice itself, or on the WaterMark Schedule of Products.

If these checks are met, then the BCA must accept the recognised product as complying with the Building Code.

If the product is used outside the scope of the recognition notice, a BCA does not have to accept it as complying with the Building Code. They may ask for further evidence in order to assess compliance with the Building Code.

Current recognition notices

Each notice listed is made under section 272HA of the Building Act and comes into force on 1 October 2025. Each notice remains in force unless amended or revoked.
