District Plans are prepared under the Resource Management Act. They set down the framework for the management of land use and subdivision in a district. They define areas (zones) for residential or industrial activities, each with its own set of rules.
There are currently two district plans for Christchurch City; the Christchurch City Plan which applies to land in the area controlled by the City prior to amalgamation with Banks Peninsula District Council while the Banks Peninsula District Plan applies to land within the former banks Peninsula district.
These plans are being reviewed and a single plan for the whole of the Christchurch is being prepared. Information about the district plan review can be viewed here.
The Christchurch City Plan is available electronically as a separate set of detailed web pages, while the Banks Peninsula District Plan is available for download in PDF format.
