Cycle of mutually-reinforcing behavioursConsistent with the terms of reference for the study, we looked at a range of things, including:

  • the industry structure for key building supplies covered by this study
  • the nature of competition for these key building supplies, including any industry pricing practices or acquisition requirements that impact on competition
  • barriers to the entry or expansion of new or innovative building supplies, such as 'green' buildings supplies or novel prefabricated products.

Full terms of reference for the study can be found here.

Over the course of the study we engaged with and gathered information from a wide range of industry stakeholders and interested parties with differing perspectives on the industry and the building regulatory system, including the five major building supplies merchants, manufacturers and importers of key building supplies, building industry representatives, government agencies, a range of industry peak bodies, and Māori partners and stakeholders.

The reports and papers produced, public versions of submissions received throughout the study and other material are available through the links below.

The available material includes links to our draft report, He Kohinga Kōrero – a summary of the key themes from a hui in May 2022 with Māori partners and stakeholders, the report of John Gardiner, the expert whom we engaged to provide advice to the Market Study, submissions on our draft report, transcripts from the consultation conference sessions and final/cross-submissions received, our final report and executive summary.

We published our final report on 6 December 2022.

We found that competition for the supply and acquisition of key building supplies is not working as well as it could if it was easier for building products to be introduced and for competing suppliers to expand their businesses. We made a suite of recommendations that aim to provide tangible improvements to competition for key building supplies, without undermining the essential policy objectives of the building regulatory system.
