Once your building work is complete you will need to apply for a Code Compliance Certificate (CCC).
A CCC is a formal statement issued under section 95 of the Building Act 2004, that building work carried out under a building consent complies with that building consent, or against the Building Code that was relevant at the time (if the consent was granted under the Building Act 1991). It is the owner’s responsibility to apply for the CCC as soon as practicable after the building work is completed.
If your building is open to the public the building cannot be used until a CCC or Certificate for Public Use is issued. It is an offence to use or permit the use of public premises affected by building work that has no code compliance certificate, certificate for public use or certificate of acceptance.
When you apply for your CCC you may be required to supply supporting documentation such as energy work certificates, producer statements, records of work etc, if applicable.
