This dataset is the definitive set of (territorial authority) subdivision boundaries for 2020,as defined by the the territorial authorities and Local Government Commissionand maintained by Stats NZ (the custodian).Subdivisions are set up under the Local Government Act 2002 and Local Electoral Act 2001. A subdivision is a division of a community or local board area for electoral purposes.Subdivisions are defined at meshblock level, and do not coincide with the statistical area 1 (SA1) geography or the statistical area 2 (SA2) geography. A number of territorial authorities do not have subdivisions, and if they do, the subdivisions do not necessarily cover the whole territorial authority area. Subdivisions nest within community or local boards. Where a community or local board is divided into subdivisions all of the community or local board area must be included in a subdivision.Subdivisions are numbered based on their corresponding territorial authority. Each subdivision has a unique five-digit number. The first three digits refer to the territorial authority that the subdivision lies within. The following two digits are sequential, and represent the number of subdivisions within the territorial authority. For example, Waipa District (017) has four subdivisions numbered 01701, 01702, 01703 and 01704. The rest of the district is not represented by a subdivision and is coded 01799 (Area Outside Subdivision).There was a large increase in the number of subdivisions between 2010 and 2011. This is due to the creation of the Auckland Council to replace Auckland Regional Council and seven territorial authorities in 2010. Twenty-one local boards were established, a number of which contain subdivisions. There was also an increase in subdivisions between 2016 and 2020 following the three-yearly representation review. Names are provided with and without tohutō/macrons. The name field without macrons is suffixed ‘ascii’.This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.Digital boundary data became freely available on 1 July 2007.
This dataset is the definitive version of the annually released (territorial authority) subdivision boundaries as at 1 January 2020, as defined by the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian), This version contains 79 subdivisions, excluding area outside subdivision.

(Territorial authority) subdivisions 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 enumeration processes easier. From the meshblock pattern, higher geographies, including the 2020 territorial authority subdivisions, were dissolved using the dissolve tool in the Arc GIS suite.
