This dataset is the definitive version of statistical area 2 (SA2) boundaries concorded to higher geographies as at 1 January 2018 as defined by Stats NZ, clipped to the coastline.
This version contains 2,171 SA2s and has been created for map creation/cartographic purposes and does not fully represent the official full extent boundaries. 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 (SA2) is a new output geography that 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.

Please note that a review of SA2 names was undertaken in early 2018. The review addressed issues with inconsistent naming and applied corrections, resulting in an update to this dataset applied in May 2018. All SA2 codes are unchanged.

Statistical Area 2 2018 (Centroid True) is the true centroid point layer for the major released version of the annually released statistical area 2 (SA2) boundaries for 2018. 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. Non-digitised meshblocks cannot have a centroid.

Please note that a review of SA2 names was undertaken in early 2018. The review addressed issues with inconsistent naming and applied corrections, resulting in an update to this dataset applied in May 2018. All SA2 codes are unchanged.

Statistical Area 2 2018 (Centroid Inside) is the inside centroid point layer for the major released version of the annually released statistical area 2 (SA2) boundaries for 2018.
The "inside" centroid is a point which always falls inside each SA2 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 the annually released urban rural boundaries at 1 January 2018, 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. Urban rural is a new output geography that classifies New Zealand into areas that share common urban or rural characteristics. Urban areas are built from the Statistical Area 2 geography, while rural and water areas are built from the Statistical Area 1 geography. Urban areas are statistically defined areas with no administrative or legal basis. The urban rural indicator is an attribute of this classification and provides additional information about a location's urban or rural nature.
