This dataset was last updated on Stats NZ Geographic Data Service on 13 Jan 2021.

This dataset is the definitive set of annually released statistical area 1 (SA1) boundaries concorded to higher geographies for 2021 as defined by Stats NZ. This version contains 29,910 SA1s including 16 with empty or null geometries (non-digitised SA1s).

This SA1 higher geographies 2021 file is a correspondence, or concordance, which relates SA1s to larger geographic areas or 'higher geographies'. The higher geographies contained in this concordance are: regional council (REGC2021), statistical area 2 (SA22021), territorial authority (TA2021), urban rural (UR2021), urban rural indicator (IUR2021), and urban accessibility indicator (IUA2021). The following geographies were introduced in 2018: statistical area 1 (SA1), statistical area 2 (SA2), urban rural (UR), and urban rural indicator (IUR) as part of the Statistical Standard for Geographic Areas 2018 (SSGA18) which replaced the 1992 New Zealand Standard Areas Classification (NZSAC92). The urban accessibility indicator (IUA), which measures the degree of urban influence New Zealand's urban areas have on surrounding rural areas, was first added to this correspondence in 2021.

Higher geography names are provided with and without tohutō/macrons, as applicable. Column names for those without macrons are suffixed ‘ascii’. For further information on individual higher geographies, refer to each geography’s metadata.

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 annually released meshblock boundaries for 2021 as defined by Stats NZ. This version contains 53,598 meshblocks, 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.

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.

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.

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

This dataset was first added to Stats NZ Geographic Data Service on 07 Dec 2020.

This dataset contains the inside centroid point layer for the annually released meshblock boundaries as at 1 January 2021. The "inside" centroid is a point which always falls inside each meshblock 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 meshblock 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. Non-digitised meshblocks cannot have a centroid.

This dataset was first added to Stats NZ Geographic Data Service on 07 Dec 2020.

This dataset is the definitive version of annually released statistical area 2 (SA2) boundaries concorded to higher geographies for 2021 as defined by Stats NZ. this version contains 2,259 categories.

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). For more information on the individual higher geographies, refer to each geography’s metadata.

SA2s were introduced as part of the Statistical Standard for Geographic Areas 2018 (SSGA2018) which replaced the New Zealand Standard Areas Classification (NZSAC1992). The SA2 geography replaces the (NZSAC1992) area unit geography.

Names are provided with and without tohutō/macrons, as applicable. Column names for those without macrons are suffixed ‘ascii’. For further information on individual higher geographies, refer to each geography’s metadata.

This dataset was first added to Stats NZ Geographic Data Service on 07 Dec 2020.

This dataset contains the true centroid point layer for the annually released meshblock boundaries as at 1 January 2021. 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 locations of a set of polygons as points, particularly when used for comparative analysis. Note that the centroid could potentially fall outside the meshblock 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.Non-digitised meshblocks cannot have a centroid.

This dataset contains the annually released statistical area 1 (SA1) boundaries for 2021, 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 29,695 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 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.

The SA1 classification can also be downloaded from the Stats NZ classification and concordance tool Ariā.

This dataset contains annually released community board boundaries for 2021 as defined by the territorial authorities and Local Government Commission but 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 187 categories.

Community boards are set up under the Local Government Act 2002 and Local Electoral Act 2001. Their purpose is to administer the affairs of communities with populations not less than 1,500 within rural, urban, or metropolitan districts of a territorial authority.

Local boards also fall within the community board classification. Local boards were introduced as part of the new local government arrangements for Auckland in 2010. Local boards share governance with a council’s governing body and each has complementary responsibilities, guaranteed by legislation. There are 21 local boards in the Auckland Council.

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