Abstract
This dataset is the definitive set of regional council constituency boundaries for 2020 as defined by the regional councils and Local Government Commission but maintained by Stats NZ (the custodian).Constituencies are established under the Local Electoral Act 2001 and result from the division of a region for electoral purposes.If a regional council decides to have a Māori constituency, the constituencies within the council are known as general constituencies and Māori constituencies.Constituencies are divisions of regional council areas. They are defined at meshblock level, and do not coincide with the statistical area 1 (SA1) geography or the statistical area 2 (SA2) geography. They are created, based on population, to be the voting areas within councils. Constituencies are required to reflect communities of interest. Their boundaries, so far as is practicable, coincide with those of territorial authorities or wards. The boundaries of constituencies may be reviewed before each three-yearly local government election. Regional councils must review their representation arrangements at least once every six years. The provisions for such reviews are in the Local Government Act 2002. Constituencies are numbered based on their corresponding regional council. Each constituency has a unique four-digit code. The first two digits represent the regional council that the constituency lies within. The last two digits are sequential and represent the number of constituencies within a regional council. For example, the West Coast Regional Council (12) contains three constituencies, which are coded 1201, 1202, and 1203.Names are provided with and without tohutō/macrons. The column name for those 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.
Purpose
This dataset is the definitive version of the annually released regional council constituency boundaries as at 1 January 2019 as defined by the territorial authorities and/or Local Government Commission, and maintained by Stats NZ. This version contains 58 constituencies, excluding area outside regional council constituency.

Constituencies 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 constituency pattern, were dissolved using the dissolve tool in the Arc GIS suite.
