Annual Boundaries Data - Page 9

Urban Area 2016 Generalised Version is the definitive set of urban area boundaries for 2016 as defined by Statistics New Zealand.

This dataset contains the annually released regional council constituency boundaries for 2021, as defined by the regional councils and/or Local Government Commission and maintained by Stats NZ (the custodian), clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 64 categories.

​

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 council are known as general constituencies and Māori constituencies.Constituencies are divisions of regional council areas. They are defined at meshblock level, and do not coincide with the statistical area 1 (SA1) geography or the statistical area 2 (SA2) geography. They are created, based on population, to be the voting areas within councils. Constituencies are required to reflect communities of interest. Their boundaries, so far as is practicable, coincide with those of territorial authorities or wards.

Names are provided with and without tohutō/macrons. The name field without macrons is suffixed ‘ascii’.

This dataset is the definitive set of territorial authority boundaries for 2001 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 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.

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.

This is the definitive set of regional council boundaries for 2001 as defined by the Local Government Commission and/or regional councils themselves but maintained by Statistics New Zealand (the custodian) as at 1 January 2001.
The regional council is the top tier of local government in New Zealand. There are 16 regional councils in New Zealand (defined by Part 1 of Schedule 2 of the Local Government Act 2002). Eleven are governed by an elected regional council, while five are governed by territorial authorities (the second tier of local government) who also perform the functions of a regional council and are known as unitary authorities. These unitary authorities are Nelson City Council, and Gisborne, Tasman, and Marlborough District Councils. The Chatham Islands Council also performs some of the functions of a regional council, but is not strictly a unitary authority. Unitary authorities act as regional councils for the purposes of a wide range of legislative purposes. Regional councils are responsible for the administration of many environmental and transport matters such as land transport planning and harbour navigation and safety.
Regional Councils were established in 1989 after the abolition of the 22 local government regions. The Local Government Act 2002 requires the boundaries of regions to conform, as far as possible, to one or more water catchments. When determining regional boundaries, the Local Government Commission gave consideration to regional communities of interest when selecting which water catchments to include in a region. It also considered factors such as natural resource management, land use planning and environmental matters. Some regional council boundaries are coterminous with territorial authority boundaries but there are several exceptions. An example is Taupo District, which is geographically split between four regions, although most of its area falls within the Waikato Region. Where territorial local authorities straddle regional council boundaries, the affected area is statistically defined by complete area units. In general, however, regional councils contain complete territorial authorities.
The seaward boundary of any coastal regional council is the twelve mile New Zealand territorial limit.

This dataset is the definitive set of the annually released regional council Māori constituency boundaries at 1 January 2019 as defined by the regional councils and/or Local Government Commission, and maintained by Stats NZ. 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.

This is the release of the annually released meshblock pattern as at 1 January 2001. This dataset is the definitive set of meshblock boundaries for 2001 as defined by Statistics New Zealand.
Statistics New Zealand maintains an annual meshblock pattern for the collection and production of statistical data, allowing data to be compared over time. A meshblock is the smallest geographic unit for which statistical data is collected and processed by Statistics New Zealand. 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 abuts against 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 territorial authority subdivision boundaries at 1 January 2018 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.
