Annual Boundaries Layers - Page 9

This dataset is the definitive set of the annually released regional council Māori 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. 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.

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 the annually released territorial authority subdivision boundaries at 1 January 2019 as defined by the territorial authorities and/or Local Government Commission, and maintained by Stats NZ. 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 and nest within community or local boards.

This dataset is the definitive set of annually released meshblock boundaries at 1 January 1991. 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 area units and urban areas. They are also used to define electoral districts, territorial authorities and regional councils.

This dataset is the definitive set of the annually released regional council boundaries at 1 January 2018 as defined by the regional council and/or Local Government Commission and maintained by Stats NZ. Regional council is the top tier of local government in New Zealand. Regional councils are defined at meshblock, statistical area 1 (SA1), and statistical area 2 (SA2) levels.

This dataset is the major released version of the annually released regional council 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. Regional council is the top tier of local government in New Zealand. Regional councils are defined at meshblock, statistical area 1 (SA1), and statistical area 2 (SA2) levels.

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.

Meshblock 2019 (Centroid True) is the true centroid point layer for the major released version of the annually released Meshblock (MB) 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 meshlock 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.

This dataset is the definitive set of statistical area 1 (SA1) true 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.

This dataset is a high definition (HD) version of the annually released meshblock boundaries concorded to higher geographies as at 1 January 2018 as defined by Stats NZ. This version contains 53,589 meshblocks. This Meshblock Higher Geographies 2018 file is a correspondence, or concordance, which relates meshblocks to larger geographic areas or 'higher geographies'. This HD version is the most detailed geometry, suitable for use in GIS for geometric analysis operations and for the computation of areas, centroids and other metrics. The HD version is aligned to the LINZ cadastre. The higher geographies contained in this concordance are: community board (CB2018), constituency (CON2018), Māori constituency (MCON2018), regional council (REGC2018), statistical area 1 (SA12018), statistical area 2 (SA22018), subdivision (TASUB2018), territorial authority (TA2018), urban rural (UR2018), urban rural indicator (IUR2018), and ward (WARD2018). The following geographies were first introduced in 2018: statistical area 1 (SA12018), statistical area 2 (SA22018), urban rural (UR2018), and urban rural indicator (IUR2018). 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.

Digital boundary data became freely available on 1 July 2007.

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 November 2018. All SA2 codes are unchanged.
