The following are the approved building consent authorities listed on the MBIE Register: Note that the register lists 80 BCAs but some of these are former territorial authorities that have been amalgamated into Auckland Council (such as Franklin District Council and North Shore City Council). Building consents on the Chatham Islands are contracted out to Wellington City Council and large dams on the Chatham's to Environment Canterbury.^[2] In addition to the regional and territorial authorities, Housing New Zealand made a decision in 2019 to establish Consentium, a national BCA in Kāinga Ora, that is responsible for building consents for public housing (up to and including four storeys) across New Zealand that Kāinga Ora intends to retain. Consentium achieved Accreditation in November 2020 and Registration in March 2021. ^[3]
