New Zealand Fire Service
A council must notify the New Zealand Fire Service about some building projects, particularly if there is to be an alteration, change of use or subdivision that affects a building's fire safety systems. This can include building work on a specified system related to fire safety, such as a sprinkler system or fire walls.
The Fire Service has 10 working days to advise of any specific fire-related requirements, such as ensuring means of escape. Your application is not suspended during this time and the council can grant your application if it doesn't receive any information from the Fire Service within the specified time period.
