Description: This dataset contains Area Units as defined by Statistics New Zealand. The development of this dataset was undertaken to allow Wellington City Council Community Services to view 2001 census information about population in CityView. Area units are aggregations of adjacent meshblocks with coterminous (having a shared border or limit) boundaries to form a single unbroken surface area (land and/or water). Exceptions to this rule are some area units comprising collections of geographically related inlets and marinas. Area units aggregate exactly to form territorial authorities and regional councils. In an urban situation area units are often equated to suburbs while in rural situations area units may be equated to localities or communities. Other layers constructed by aggregating meshblocks are Wards, Regional Constituencies, General and Maori electoral.
