Annual Boundaries Data - Page 9

This dataset is the definitive set of regional council Māori constituency boundaries for 2015 as defined by the regional councils and Local Government Commission but maintained by Statistics New Zealand (the custodian).

​

Māori constituencies are established under the Local Electoral Act 2001 and result from the division of a region for electoral purposes. Māori constituencies are divisions of regional council areas. They are created, based on population, to be the voting areas within councils.

​

The boundaries of Māori constituencies may be reviewed before each three-yearly local government election. Regional councils must review their representation arrangements at least once every six years.

This dataset is the definitive set of area unit boundaries for 2015 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).

​

The area unit pattern is revised once every five years in the year immediately before a Census of Population and Dwellings. There may also be changes in other years, in conjunction with local body boundary changes.

This dataset is the definitive set of 2018 meshblock boundaries and higher geographies that may be used with the Regional Council Urban Accessibility Indicator 2018 (RC_IUA 2018). The higher geographies in this dataset are statistical area 1 (SA1), urban accessibility indicator (IUA) and regional council (REGC). This version contains 53,589 meshblocks.

This dataset contains the annually released meshblock boundaries for 2020, as defined by Stats NZ, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 52,929 meshblocks.

Stats NZ maintains an annual meshblock geography for collecting and producing statistical data. This allows data to be compared over time. A meshblock is the smallest geographic unit for which statistical data is collected and processed by Stats NZ. A meshblock is defined by a geographic area, which can vary in size from part of a city block to a large area of rural land. Each meshblock borders on another to form a network covering all of New Zealand, including coasts and inlets and extending out to the 200-mile economic zone. Meshblocks are added together to build up larger geographic areas such as statistical area 1 (SA1), statistical area 2 (SA2), and urban rural. They are also used to define electoral districts, territorial authorities, and regional councils.

The following 16 meshblocks are outside the 12 mile limit and are not held in digitised form: 0016901, 0016902, 1588000, 3166401, 3166402, 3166600, 3166710, 3166711, 3195000, 3196001, 3196002, 3196003, 3196004, 3196005, 3196006, 3196007.

The meshblock classification can also be downloaded from the Stats NZ classification and concordance tool Ariā.

This dataset is the definitive set of statistical area 2 (SA2) boundaries at 1 January 2019, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and may not fully represent the official full extent boundaries. SA2 is a new output geography that provides higher aggregations of population data than can be provided at the statistical area 1 (SA1) level. SA2s are defined at meshblock and SA1 levels.

This dataset is the definitive set of annually released territorial authority boundaries at 1 January 2019 as defined by the territorial authorities and/or Local Government Commission, and maintained by Stats NZ. A territorial authority is defined under the Local Government Act 2002 as a city or a district council. Territorial authorities are the second tier of local government in New Zealand, below regional councils.

This dataset is the definitive set of annually released statistical area 1 (SA1) boundaries for 2020 as defined by Stats NZ. This version contains 29,895 SA1 categories.

SA1s were introduced as part of the Statistical Standard for Geographic Areas 2018 (SSGA18) which replaced the New Zealand Standard Areas Classification (NZSAC92). SA1 is a new output geography that allows the release of more detailed information about population characteristics than is available at the meshblock level.

Built by joining meshblocks, SA1s have an ideal size range of 100–200 residents, and a maximum population of about 500. This is to minimise suppression of population data in multivariate statistics tables. SA1s either define or aggregate to define SA2s, urban rural areas, territorial authorities, and regional councils. Some SA1s that contain apartment blocks, retirement villages, and large non-residential facilities have more than 500 residents.

This dataset is the definitive set of annually released (territorial authority) subdivision boundaries for 2021, as defined by the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian). This version contains 145 categories.

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.

Names are provided with and without tohutō/macrons. The name field without macrons is suffixed ‘ascii’.

This dataset contains the inside centroid point layer for the annually released statistical area 2 (SA2) boundaries as at 1 January 2020.The "inside" centroid is a point which always falls inside each SA2 polygon as this is often desirable. The placement of the point is typically in the widest part of the polygon. The algorithms used are proprietary to ESRI and are related to label placement. Note that the "inside" centroid is NOT always the same as the center of gravity ("true" centroid) of the polygon as in some situations the true centroid may fall outside the SA2 geometry. The dataset contains the EASTING and NORTHING attributes of the centroid point in NZGD2000 New Zealand Transverse Mercator (EPSG:2193) and LATITUDE and LONGITUDE of the centroid point in decimal degrees in WGS1984 (EPSG:4326) projection.
