BRANZ. Welcome to BRANZ



The Up-Spec performance upgrades are based on independent research by BRANZ and were developed in consultation with the homebuilding and environmental advisory community.

BRANZ is an independent and impartial research, testing, consulting and information company providing services and resources for the building industry.

Our two main areas of activity are to:

  • research and investigate the construction and design of buildings that impact the built environment in New Zealand
  • enable the transfer of knowledge from the research community into the commercial building and construction industry.

 Our core purpose is to improve people's lives through our research and to inform, educate and motivate those who shape the built environment.
