Christchurch City Council had its building consents accreditation removed because it was granting consents that could potentially put people and property at risk, International Accreditation New Zealand says.
The organisation revoked the council's accreditation on Monday, after it failed to improve its consenting process over the last month.
However, the council will continue to issue consents even though they will no longer be approved by the independent authority International Accreditation New Zealand (IANZ) from next Monday onwards.
Christchurch Mayor Bob Parker said the move was unlikely to make any difference to the council, and it would be "business as usual".
IANZ last month warned the council that they had to speed up the flow of consent approvals, or they faced losing accreditation.
