2019 Data - Page 4

This dataset is the definitive set of the annually released territorial authority subdivision 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. 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 nest within community or local boards.

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 dataset is the definitive set of annually released regional council constituency 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. Constituencies are established under the Local Electoral Act 2001 and result from the division of a region for electoral purposes. If a regional council decides to have a Māori constituency, the constituencies within the region are known as general constituencies and Māori constituencies. Constituencies are divisions of regional council areas. They are defined at meshblock level.

This dataset is the definitive set of statistical area 1 (SA1) inside centroid point layer for the major released version of the annually released statistical area 1 (SA1) boundaries as at 1 January 2019 as defined by Stats NZ.

The "inside" centroid is a point which always falls inside each SA1 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.
