Background
The Building Act 2004 (the Act) gave responsibilities relating to dams to Regional Authorities – Regional Councils and Unitary Authorities. Provisions in the Act that relate to dams include:
- Building control functions – building consents, code compliance certificates, Project Information memoranda
- Dam safety scheme – potential impact categories, dam safety assurance programmes, annual compliance certificates, dangerous dams
Building control functions and the dam safety scheme only apply to large dams. The construction of dams that are not large do not require a building consent but are still required to comply with the building code.
Greater Wellington has transferred most of its building control functions to Waikato Regional Council. Waikato Regional Council has specialist expertise on the building consent process and is accredited as a Building Consent Authority (BCA).
