BRANZ. Welcome to BRANZ



 Type Tests, Technical Opinions & Nail List



BRANZ Type Tests and BRANZ Technical Opinions, together with BRANZ Appraisals, ensure that BRANZ can offer you a full suite of product verification services to meet your needs.

BRANZ Type Tests and BRANZ Technical Opinions complement BRANZ Appraisals. They may be disclosed to design teams, builders and building consent authorities (BCAs) for the purpose of helping to demonstrate compliance with the New Zealand Building Code (NZBC) or show that third-party independent testing or assessment has been carried out on the product in question.  

Key benefits 

  • Intended for products that do not require the full rigour of an Appraisal.
  • BRANZ Type Tests and BRANZ Technical Opinions can be published and disclosed to design teams, builders and building consent authorities.
  • Provides independent third-party assessment for lower-risk products.
  • BRANZ Type Tests and BRANZ Technical Opinions will be listed on our website at your discretion.  

BRANZ Technical Opinions

This service is intended for relatively low-risk products that are expected to have a long history of use in service and, therefore, a good track record of performance. Technical Opinions will normally be against single NZBC clauses.

BRANZ Type Tests

This service is available for low to medium-risk products and systems. Tests are carried out against published criteria such as an NZBC referenced standard or where other robust criteria can be or have been developed. Tests will be available against a single NZBC performance requirement, for example, establishing Group Numbers for lining materials in accordance with ISO 9705 and ISO 5660 Part 1 and 2

Test results will be published in a Summary Type Test Report, on the BRANZ website, that states clearly the sample product provided to BRANZ, the test method and the results obtained.

A full BRANZ Type Test Report will also be provided, which you may publish.
