2019 Data - Page 4

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.

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 major released version of the annually released meshblock boundaries concorded to higher geographies at 1 January 2019. This version contains 53,596 meshblocks, including 16 with empty or null geometries (non-digitised meshblocks).

This Meshblock Higher Geographies 2019 (generalised) file is a correspondence, or concordance, which relates meshblocks to larger geographic areas or 'higher geographies'. This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

The higher geographies contained in this concordance are: community board (CB2019), constituency (CON2019), Māori constituency (MCON2019), regional council (REGC2019), statistical area 1 (SA12019), statistical area 2 (SA22019), subdivision (TASUB2019), territorial authority (TA2019), urban rural (UR2019), urban rural indicator (IUR2019), and ward (WARD2019).

The following geographies were first introduced in 2018: statistical area 1 (SA1), statistical area 2 (SA2), urban rural (UR), and urban rural indicator (IUR). These new geographies are 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.
