NZ Constituencies - Archive

Topicality: 01-01-2026 Projection: New Zealand Transverse Mercator (NZTM) This layer contains the archive of regional council constituency boundaries for 2021 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. This layer get updated yearly with the latest boundary data. You can use this layer when you need any year of boundary data in your map. By setting a filter on the dataset year you can filter on specific year of the dataset. For information about the fields in this dataset go to the Data tab. The layer is further generalised by Eagle Technology for improved performance on the web, therefore it doesn't fully represent the official boundaries. If you only need the latest boundary data in your map you can use the current version of this dataset. All the current versions of Stats NZ Boundary layers can be found here. The official dataset can be found on https://datafinder.stats.govt.nz. This layer is offered by Eagle Technology (Official Esri Distributor). Eagle Technology offers services that can be used in the ArcGIS platform. The Content team at Eagle Technology updates the layers on a regular basis and regularly adds new content to the Living Atlas. By using this content and combining it with other data you can create new information products quickly and easily.
