Annual Boundaries Layers - Page 4

MB2018_V1_00_Centroid_True is the true centroid point layer for the major released version of the annually released meshblock 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 locations of a set of polygons as points, particularly when used for comparative analysis. Note that the centroid could potentially fall outside the meshblock 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.

SA12018_V1_00_Centroid_True is the true centroid point layer for the major released version of the annually released statistical area 1 (SA1) boundaries as at 1 January 2018 as defined by Stats NZ. 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 SA1 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 Meshblock Higher Geographies 2017 (high definition) file is a correspondence, or concordance, which relates meshblocks to larger geographic areas or 'higher geographies'. A high definition version is the highest geographic resolution geometry and is aligned to the LINZ cadastre.
The higher geographies contained in this concordance are: area unit (AU2017), community board (CB2017), constituency (CON2017), Māori constituency (MCON2017), regional council (REGC2017), subdivision (TASUB2017), territorial authority (TA2017), urban area (UA2017) and ward (WARD2017).

Digital boundary data became freely available on 1 July 2007.

For further information on individual higher geographies, refer to their metadata.

This dataset is the definitive set of annually released territorial authority 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. A territorial authority is defined under the Local Government Act 2002 as a city or a district council. Territorial authorities are the second tier of local government in New Zealand, below regional councils.

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 is the release of the annually released meshblock pattern as at 1 January 2006. This dataset is the definitive set of meshblock boundaries for 2006 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 major released version of the annually released regional council 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. 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 is the definitive set of area unit boundaries for 2006 as defined by Statistics New Zealand as at 1 January 2006.
Area units are aggregations of adjacent meshblocks with coterminous boundaries to form a single unbroken surface area (land and/or water). Exceptions to this rule are some area units comprising collections of geographically related inlets and marinas.
In an urban location, an area unit is often a collection of city blocks, while in rural situations area units may be equated to localities or communities. Area units must either define or aggregate to define urban areas, rural centres, statistical areas, territorial authorities, and regional councils.
Each area unit must be a single geographic entity with a unique name. The area unit pattern is revised once every five years in the year immediately before a Census of Population and Dwellings. There may also be changes in other years, in conjunction with local body boundary changes. Statistics New Zealand maintains a concordance file to ensure boundaries relating to earlier area unit patterns can also be generated.

Ward 2016 Generalised Version is the definitive set of ward boundaries at 1 January 2016 as defined by the territorial authorities and/or Local Government Commission, but maintained by Statistics New Zealand (the custodian).

This is the definitive set of area unit boundaries for 2001 as defined by Statistics New Zealand as at 1 January 2001.

This is the definitive set of regional council boundaries for 2006 as defined by the Local Government Commission and/or regional councils themselves but maintained by Statistics New Zealand (the custodian) as at 1 January 2006.
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.
