Statistical Area 2 2020 (generalised)
This dataset was last updated on Stats NZ Geographic Data Service on 25 Jun 2020.
This dataset is the definitive set of statistical area 2 (SA2) boundaries for 2020 as defined by Stats NZ. This version contains 2,255 SA2 categories.
SA2s were introduced as part of the Statistical Standard for Geographic Areas 2018 (SSGA2018) which replaced the New Zealand Standard Areas Classification (NZSAC1992). The SA2 geography replaces the (NZSAC1992) area unit geography.
SA2 is an 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.
SA2s are built from SA1s and either define or aggregate to define urban rural areas, territorial authorities, and regional councils. SA2s in city council areas generally have a population of 2,000–4,000 residents while SA2s in district council areas generally have a population of 1,000–3,000 residents. In rural areas, many SA2s have fewer than 1,000 residents because they are in conservation areas or contain sparse populations that cover a large area.
Names are provided with and without tohutō/macrons. The name field without macrons is suffixed 'ascii'.
This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.
Digital boundary data became freely available on 1 July 2007.

Territorial Authority 2020 (generalised)
This dataset was last updated on Stats NZ Geographic Data Service on 29 Jan 2020.
This dataset is the definitive set of annually released territorial authority boundaries for 2020 as defined the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian). This version contains 68 categories.
A territorial authority is defined under the Local Government Act 2002 as a city or a district council. There are 67 territorial authorities in New Zealand. Some territorial authority boundaries are coterminous with regional council boundaries but there are several exceptions. An example is Taupo District, which is split between four regions, although most of its area falls within the Waikato Region. Territorial authorities are defined at meshblock, statistical area 1 (SA1) and statistical area 2 (SA2) levels.
This dataset is the definitive set of statistical area 2 (SA2) boundaries at 1 January 2018 as defined by Stats NZ. SA2 is a new output geography that provides higher aggregations of population data than can be provided at the statistical area 1 (SA1) level. SA2s are defined at SA1 and meshblock levels. 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. For further information see ANZLIC Metadata 2018 Statistical Area 2 attachment below or link to the StatsNZ Classification System Aria.
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.
Regional Council 2020 (generalised)
This dataset is the definitive version of the annually released regional council boundaries for 2020 as defined by the regional councils and/or Local Government Commission, and maintained by Stats NZ (the custodian). This version contains 17 categories.
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.
Auckland Council unitary authority was formed in 2010, under the Local Government (Tamaki Makarau Reorganisation) Act 2009, replacing the Auckland Regional Council and seven territorial authorities.The seaward boundary of any coastal regional council is the twelve-mile New Zealand territorial limit. Regional councils are defined at meshblock and statistical area 2
This dataset is the definitive set of statistical area 2 (SA2) boundaries for 2022 as defined by Stats NZ (the custodian). This version contains 2,260 SA2 features.
This dataset is the definitive set of statistical area 1 (SA1) boundaries at 1 January 2018 as defined by Stats NZ. SA1 is a new output geography that allows for 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.

District Health Board 2015
This dataset was first added to Stats NZ Geographic Data Service on 17 Aug 2017.
District Health Boards are responsible for providing or buying Government funded health care services for the population of a specific geographical area. District Health Boards have existed since 1 January 2001. The amalgamation of Otago and Southland into the Southern District Health Board in 2010 reduced the number of District Health Boards from 21 to 20 (excluding 'Area outside District Health Board')
District Health Boards are defined at meshblock level.
Changes to District Health Boards:
Otago and Southland amalgamated to form the Southern District Health Board in 2010.
Chatham Islands Territory meshblocks transferred from Hawke's Bay District Health Board to Canterbury District Health Board in 2015.
Further information on District Health Boards can be found on the Ministry of Health website: www.health.govt.nz/new-zealand-health-system/key-h...
Urban Accessibility Indicator 2021 (generalised)
The urban accessibility (UA) classification measures the degree of urban influence New Zealand's urban areas have on surrounding rural areas. It classifies the geographic accessibility of rural statistical area 1s (SA1s) and small urban areas according to their proximity, or degree of remoteness, to larger urban areas. This classification provides increased understanding of the heterogeneity of rural areas and small urban areas and will allow more extensive analysis and reporting. Understanding the degree of urban accessibility or remoteness is important as it has a major influence on the employment sector, accessibility to services, and population composition and change.
The methodology uses drive time from an SA1 address weighted centroid to the outside boundary of the nearest major, large, and medium urban area (from Stats NZ urban rural (UR) classification) to classify rural SA1s and small urban areas to one of five categories of accessibility or remoteness. The Open Source Routing Machine service using the OpenStreetMap road network is used to calculate the drive times.
A concordance between SA1 and Urban Accessibility can be found on Aria.
Urban accessibility indicator is also available as an attribute on Statistical Area 1 Higher Geographies 2021 (generalised).
Rural SA1s and small urban areas are classified to the following categories:
·High urban accessibility:
0 to15 minutes from major urban areas
·Medium urban accessibility:
15 to 25 minutes from major urban areas
0 to 25 minutes from large urban areas
0 to 15 minutes from medium urban areas
·Low urban accessibility:
25 to 60 minutes from major or large urban areas
15 to 60 minutes from medium urban areas
·Remote:
60 to 120 minutes from major, large or medium urban areas
·Very remote:
more than 120 minutes from major, large or medium urban areas
For more information refer to: Urban accessibility - methodology and classification.
The full classification is shown below:
111 Major urban area
112 Large urban area
113 Medium urban area
221 High urban accessibility
222 Medium urban accessibility
223 Low urban accessibility
224 Remote
225 Very remote
331 Inland water
332 Inlet
333 Oceanic
Areas of 221 High urban accessibility and 222 Medium urban accessibility may be regarded as peri-urban in nature and combined with urban areas for analytical purposes.
Meshblock 2021 (generalised)
This dataset is the definitive set of annually released meshblock boundaries for 2021 as defined by Stats NZ. This version contains 53,598 meshblocks.
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 statistical area 1 (SA1), statistical area 2 (SA2), and urban rural. They are also used to define electoral districts, territorial authorities, and regional councils.
The following 16 meshblocks are outside the 12 mile limit and are not held in digitised form: 0016901, 0016902, 1588000, 3166401, 3166402, 3166600, 3166710, 3166711, 3195000, 3196001, 3196002, 3196003, 3196004, 3196005, 3196006, 3196007.
The meshblock classification can also be downloaded from the Stats NZ classification and concordance tool Ariā.
