This dataset is the definitive version of statistical area 2 (SA2) boundaries concorded to higher geographies as at 1 January 2019 as defined by Stats NZ.

This statistical area 2 higher geographies file is a correspondence, or concordance, which relates SA2s to larger geographic areas or 'higher geographies'. The higher geographies contained in this concordance are: territorial authority (TA) and regional council (REGC).

Statistical area 2 was created as part of the Statistical Standard for Geographic Areas 2018 (SSGA18) which replaces the 1992 New Zealand Standard Areas Classification (NZSAC92). The statistical standard for geographic areas is to be used from 2018 (SSGA18). It defines the Stats NZ input and output geographic classifications and describes their primary purposes, and sets out requirements and guidelines for the creation and maintenance of statistical geographies.

Statistical area 2 (SA2) provides higher aggregations of population data than can be provided at the statistical area 1 (SA1) level. The SA2 geography aims to reflect communities that interact together socially and economically. In populated areas, SA2s generally contain similar sized populations.

Digital boundary data became freely available on 1 July 2007. This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

This Meshblock Higher Geographies 2017 (high definition) file is a correspondence, or concordance, which relates meshblocks to larger geographic areas or 'higher geographies'. A high definition version is the highest geographic resolution geometry and is aligned to the LINZ cadastre.
The higher geographies contained in this concordance are: area unit (AU2017), community board (CB2017), constituency (CON2017), Māori constituency (MCON2017), regional council (REGC2017), subdivision (TASUB2017), territorial authority (TA2017), urban area (UA2017) and ward (WARD2017).

Digital boundary data became freely available on 1 July 2007.

This dataset was first added to Stats NZ Geographic Data Service on 01 Dec 2021.

This dataset contains the true centroid point layer for the annually released statistical area 2 (SA2) boundaries for 2022 as defined by Stats NZ (the custodian). The "true" centroid is the centre of mass of that polygon, such that if some flat substance of uniform thickness and density were cut into the shape of that polygon, then that object would balance at the centroid. The centroid is a useful way of summarizing the location of a set of polygons as points, particularly when used for comparative analysis. Note that the centroid could potentially fall outside the SA2 polygon, depending on the shape of the polygon. 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.

This dataset is the definitive set of meshblock boundaries for 2017 as defined by Statistics New Zealand.

Statistics New Zealand maintains an annual meshblock pattern 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 Statistics New Zealand. 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 area units and urban areas. They are also used to define electoral districts, territorial authorities, and regional councils.

This dataset was last updated on Stats NZ Geographic Data Service on 29 Jan 2020.

This dataset contains the annually released territorial authority boundaries for 2020, as defined by the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian), 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 68 categories.

A territorial authority is defined under the Local Government Act 2002 as a city or a district council. There are 67 territorial authorities in New Zealand. Some territorial authority boundaries are coterminous with regional council boundaries but there are several exceptions. An example is Taupo District, which is split between four regions, although most of its area falls within the Waikato Region. Territorial authorities are defined at meshblock, statistical area 1 (SA1) and statistical area 2 (SA2) levels.

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 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 a high definition (HD) version of the annually released meshblock boundaries at 1 January 2018. This HD version is the most detailed geometry, suitable for use in GIS for geometric analysis operations and for the computation of areas, centroids and other metrics.

A meshblock is the smallest geographic unit for which statistical data is collected and processed by Stats NZ.

They are also used to define electoral districts, territorial authorities, and regional councils. The digital geographic boundaries are defined and maintained by Stats NZ. Meshblocks cover the land area of New Zealand, the water area to the 12-mile limit, the Chatham Islands, Kermadec Islands, sub-Antarctic islands, off-shore oil rigs, and Ross Dependency.

Digital boundary data became freely available on 1 July 2007.

There are 16 meshblocks not held in digitised form.
