MB2015_V1_00_Centroid_Inside is the inside centroid point layer for the major released version of the annually released meshblock pattern as at 1 January 2015. The "inside" centroid is a point which always falls inside each Meshblock polygon as this is 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 centre 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 version contains 47,046 Meshblock inside centroid points. Non-digitised meshblocks do not have have an inside centroid.

MB2018_V1_00_Centroid_Inside is the inside centroid point layer for the major released version of the annually released meshblock boundaries as at 1 January 2018.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 statistical area 1 (SA1) 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. SA1 is a new output geography that allows the release of more detailed information about population characteristics than is available at the meshblock level. SA1s are defined at meshblock level.

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 a definitive set of territorial authority boundaries for 2006 as defined by the Local Government Commission and/or the territorial authorities themselves but maintained by Statistics New Zealand (the custodian). A territorial authority is defined under the Local Government Act 2002 as a city or a district council.

This dataset is the definitive set of territorial authority boundaries for 2015 as defined by the Local Government Commission and/or the territorial authorities themselves but maintained by Statistics New Zealand (the custodian). A territorial authority is defined under the Local Government Act 2002 as a city or a district council.

2013 Census meshblock dataset contains counts at meshblock levels for selected variables from the 2013 Census. The geographies correspond to 2013 Census boundaries. The counts are at the highest level of each variable’s classification.

Wards were originally set up within any territorial authority with a population of 20,000. Wards are defined under the local Electoral Act 2001 and result from the division, of the district of a territorial authority for electoral purposes. Ward boundaries are reviewed in the year immediately preceding the triennial local government elections. Wards are numbered based on their corresponding territorial authority. Each ward has a unique five digit number. The first three digits represent the territorial authority that the ward lies within. The following two digits are sequential, and represent the number of wards within a territorial authority.

This dataset is the definitive set of territorial authority subdivision boundaries for 2017 as defined by the territorial authorities and Local Government Commission but maintained by Statistics New Zealand (the custodian).

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.

This dataset is the definitive set of regional council Māori constituency boundaries for 2017 as defined by the regional councils and Local Government Commission but maintained by Statistics New Zealand (the custodian).

Māori constituencies are established under the Local Electoral Act 2001 and result from the division of a region for electoral purposes.

Māori constituencies are divisions of regional council areas. They are created, based on population, to be the voting areas within councils. Māori constituencies are defined at meshblock level, and do not coincide with area units.
