Area Unit 2016 Generalised Version

Statistics New Zealand

Area Unit 2016 Generalised Version is the definitive set ofarea unit boundaries for 2016 as defined by Statistics New Zealand. Area units are aggregations of adjacent meshblocks with coterminous 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 are non-administrative areas intermediate in size between meshblocks and territorial authorities. In an urban location, an area unit is often a collection of city blocks, while in rural situations area units may be equated to localities or communities. Area units must either define or aggregate to define urban areas, rural centres, statistical areas, territorial authorities, and regional councils. Each area unit must be a single geographic entity with a unique name. The area unit pattern is revised once every five years in the year immediately before a census. There may also be changes in other years, in conjunction with local body boundary changes. Statistics New Zealand maintains a concordance file to ensure boundaries relating to earlier area unit patterns can also be generated. Digital boundary data became freely available on 1 July 2007. For full metadata, please refer to the metadata documents on the Stats NZ website: http://www.stats.govt.nz/browse_for_stats/Maps_and_geography/Geographic-areas/digital-boundary-files.aspx#metadata

Area units are based on the meshblock pattern. Non-alignment of meshblock and cadastral boundaries are one of a number of reasons for meshblock boundary adjustments. Other reasons include requests from local authorities, Local Government Commission, Electoral Representation Commission and to make Census of Population and Dwellings enumeration processes easier. From the meshblock pattern, higher geographies, including the 2016 area unit pattern, were dissolved using the dissolve tool in the Arc GIS suite. To derive the area unit boundaries clipped to the coastline, meshblock polygons were dissolved to exclude meshblocks with a land/water attribute of Inlet or Oceanic.

These conditions of supply apply to all users of Statistics New Zealand digital boundaries effective 1 July 2007.
