Statistical Area 2 2019 (Centroid True) is the true centroid point layer for the major released version of the annually released statistical area 2 (SA2) boundaries for 2019.

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 was first added to Stats NZ Geographic Data Service on 03 Dec 2018.

This dataset is the definitive set of the meshblock (MB) inside centroid point layer for the major released version of the annually released meshblock boundaries as at 1 January 2019.

The "inside" centroid is a point which always falls inside each meshblock polygon as this is often desirable in some users cases. 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 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.

This dataset is the definitive set of annually released meshblock boundaries at 1 January 2019. 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 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. This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

There are 16 meshblocks not held in digitised form.

Territorial Authority 1995 is based on Meshblock 1996 as there is no digital pattern available for Meshblock 1995. Meshblocks are the lowest level building block geography and are aggregated to form higher geographies such as territorial authority, wards, statistical area 1 etc.. From the meshblock pattern,Territorial Authority 1995 was dissolved using the dissolve tool in the Arc GIS suite.

This dataset is the definitive version of the annually released statistical area 1 (SA1) boundaries concorded to higher geographies at 1 January 2019.

This statistical area 1 higher geographies 2019 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 (REGC2019), statistical area 2 (SA22019), territorial authority (TA2019), urban rural (UR2019), and urban rural indicator (IUR2019).The following geographies were introduced in 2018: statistical area 1 (SA12018), statistical area 2 (SA22019), urban rural (UR2019), and urban rural indicator (IUR2019).

Statistical area 1 (SA1) 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 geographies are aggregations of meshblocks optimised to be of similar population sizes to enable the release of low-level data. They are non-administrative areas that are in between meshblocks and territorial authorities in size. Statistical areas either define or aggregate to define urban rural areas, territorial authorities, and regional councils.

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.
