Our role, as the over-arching regulator, is to work with stakeholders so we can deliver fit-for-purpose, performance-based building regulation that protects the public's safety and property and helps lift the sector’s performance.

We work with building practitioners, officials, consumers and other regulators to understand what matters to them, and to ensure they understand their roles and responsibilities. We do this by providing clear, effective guidelines, information, education and enforcement.

We have a range of statutory responsibilities for building and housing, and administer New Zealand’s building legislation. We also work with other regulators whose legislation has an impact on the building sector.
