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

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.

Purpose:This data is primarily used by council and its contractors in identifying the location of the asset.Lineage:This data was a product of consolidating legacy GIS datasets from the previous regional council and seven city and district councils. Since amalgamation in 2010, the data has been updated by Asset Management teams. Polygon data is digitised from urban aerial photographs and from asset as-built drawings; positional accuracy is around 50cm. Attribute information is field validated by inspections during park audits and asset turnover process.Creation Date:1/04/2012Update Cycle:Daily

Topicality: 01-01-2025Projection: New Zealand Transverse Mercator (NZTM)This layer contains the archive of the Territorial Authority and Local Board boundaries maintained by Stats NZ.This dataset is a derived version comprising local boards for Auckland and territorial authorities for the rest of New Zealand, as defined by the territorial authorities 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.For statistical outputs that use territorial authorities to aggregate and report data Auckland Council is treated as a single geographic entity. This can hide meaningful patterns and trends for a significant portion of the population. A solution was to create a new classification of territorial authorities that includes the local boards for Auckland. The Auckland Council was established in 2010 under the Local Government (Tamaki Makaurau Reorganisation) Act 2009. Seven territorial authorities within the Auckland Region were abolished and replaced by the unitary authority Auckland Council. Local boards fall within the community board classificationThis layer get updated yearly with the latest boundary data. You can use this layer when you need any year of boundary data in your map.

In 2022, Auckland Council contracted Aerial Surveys Ltd to supply 0.075 m GSD digital ortho imagery covering the Auckland region. Aerial photography was captured over the Auckland Region and the Hunua Ranges, totalling approximately 6,130 km2.Data Acquisition The aerial photography for this project was captured within the 2023/24 flying season (September 2023 –April 2024) and 2024/25 flying season (September 2024 – April 2025). The aerial imagery was captured on the following dates: 1 February 2024, 24 February 2024, 28-29 February 2024, 1 March 2024, 9-10 March 2024, 16 March 2024, 19-21 March 2024, 31 March 2024, 8 May 2024, 11 May 2024, 11-14 January 2025, 5-6 March 2025.Imagery SpecificationOrtho imagery: Three-bandSpectral resolution: Near Infrared, Green, BlueRadiometric resolution: RGB 24 bit, RGBI 32 bit (8 bits per each band)Pixel resolution: 0.075 m GSD (7.5 cm)Tile index: Tile index for the project areaSpatial accuracy: ±0.15 m @ 95% confidence level in clear flat open spaces (2 sigma)Aligned to LINZ 1:1,000 map sheet layout (480 m x 720 m)Tiles supplied: 18,230 (1:1,000 map sheet tiles)Image format: JPEGNote: Auckland Council can provide R-G-B-NIR imagery for the area in GEOTIFF format as well. Please contact us at gis@aklc.govt.nz to request the four-band imagery.Map ProjectionAll spatial data for this project is provided in terms of New Zealand Transverse Mercator 2000 map projection (NZTM2000). The ellipsoidal datum is New Zealand Geodetic Datum 2000 (NZGD2000). The airborne GPS and ground control GPS data was converted from ellipsoidal heights into orthometric heights using the LINZ NZGeoid16 separation model. For this project, the orthometric vertical datum is New Zealand Vertical Datum 2016 (NZVD2016).Map ProjectionAll spatial data for this project provided in terms of New Zealand Transverse Mercator 2000 map projection (NZTM2000). The ellipsoidal datum is New Zealand Geodetic Datum 2000 (NZGD2000). The airborne GPS and ground control GPS data was converted from ellipsoidal heights into orthometric heights using the LINZ NZGeoid16 separation model. For this project the orthometric vertical datum is New Zealand Vertical Datum 2016 (NZVD2016).Camera and Flying HeightMost of the photography was captured using Vexcel's digital UltraCam Eagle Mark 3 (UCE-3) and UltraCam Eagle Prime (UCE-p) camera fitted with the 100 mm lens and flown at an altitude of approximately 4,732 ft (1,442 m) with the lowest ground GSD set at 0.075 m. These cameras are fitted to a GSM 3000 gyro-stabilised mount and IGI AEROcontrol GNSS/IMU positioning system. Some portions were flown using Vexcel's digital UltraCamLp (UCLp) camera fitted with the 70 mm lens and flown at an altitude of approximately 2,952 ft (900 m).Sun AngleImagery captured with a minimum sun angle of +40 degrees subject to a 5-degree tolerance when capture is in progress. It was agreed (February 2024) to lower the sun angle to +30 degrees over rural areas and +40 degrees over urban/city areas. The sun angle of the imagery used for the orthorectification ranged from 24 to 75 degrees.Flight PlanningThe flight survey number for this project is SN14259.The flight plan is named ‘Auck_075cm_UCLp_v3’ and comprises 137 runs, 11,975 frames. All imagery captured in stereo: forward overlap 60%, min 54%; side overlap 35%, min 15%. Imagery over CBD and tall building areas captured in stereo: forward overlap 80%; side overlap 80%. The additional flight plan is named ‘Auckland-80x80-2022-23-7-5cm-UCE3’ and comprises 17 runs, 218 frames.Urban Building Displacement SpecificationUrban 0.075 m GSD imagery – using the UCE-3, UCEp and UCLp cameras and by flying with 60% forward overlap and with 35% sidelap (standard stereo coverage) will achieve <1 m building lean per 3 m height in the corners of the imagery used. Tall structures inwards of the corner of the frame will have less lean the closer to the nadir they are. <0.37 m building lean per 3 m of height in the corners of the imagery using increased 80/80 overlap in the CBD area. Very tall buildings have been further straightened using manual techniques. To help reduce building lean in the CBD area additional processing has been applied to produce true orthos for building verticality.Ground ControlA combination of existing control and LINZ benchmarks were observed for use with the aerial triangulation and bundle adjustment.DTM for Ortho ProductionThe digital terrain model used for this project was derived from LiDAR DTM data flown in 2015. Outside the LiDAR DTM a new DTM was collected from the 0.075 m GSD stereo imagery using photogrammetric techniques, largely automated pixel matching and autocorrelation process. The DTM data was merged seamlessly and accuracy checked to meet the ortho imagery specification. The DTM was further processed and edited suitable for the ortho production.

This dataset is the definitive version of the annually released regional council boundaries as at 1 January 2023 as defined by regional councils and/or Local Government Commission, and maintained by Stats NZ (the custodian). This version contains 16 regional councils and area outside region (Chatham Islands Territory). The annual boundaries are used for the full calendar year from 1 January. The annual update may have no changes from the previous release.

​

The regional council is the top tier of local government in New Zealand. Regional councils are defined under schedule 2, part 1 of the Local Government Act 2002. They were established in November 1989 after the abolition of the 22 local government regions. Regional council boundaries must coincide with meshblock boundaries under schedule 3, clause 17 of the Local Government Act 2002.

​

Regional council boundaries are based largely on water catchments, such as rivers, lakes, and harbours. The seaward boundary of the regions is the 12 mile (19.3km) New Zealand territorial limit. In determining regions, consideration was also given to regional communities of interest, natural resource management, land use planning, and environmental matters.

​

There are 16 regions which cover every territorial authority in New Zealand, with the exception of the Chatham Islands Territory (included in 99 Area Outside Region). Five regions are administered as unitary authorities, which function as both regional council and territorial authority. These unitary authorities are Auckland Council, 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 legislative purposes. Regional councils are responsible for administrating many environmental and transport matters, such as land transport planning and harbour navigation and safety.

​

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 authorities straddle regional council boundaries, the affected area is statistically defined by complete regional councils. In general, however, regional councils contain complete territorial 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.

​

Regional councils are defined at meshblock level. Statistical area 1 and statistical area 2 geographies nest within regional council boundaries.

​

Numbering

The standard classification of regional council is a flat classification and contains 17 categories (including ‘99 Area Outside Region’).

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 considered 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.

This dataset is the definitive version of the annually released territorial authority boundaries as at 1 January 2023 as defined by territorial authorities and/or Local Government Commission, and maintained by Stats NZ (the custodian). This version contains 67 territorial authorities, excluding ‘area outside territorial authority’.

​

Territorial authorities are the second tier of local government in New Zealand, below regional councils. They are defined under schedule 2, part 1 of the Local Government Act 2002 as city councils or district councils. Territorial authorities were established in 1989 when 205 territorial local authorities were replaced by 75 territorial authorities. Territorial boundaries must coincide with meshblock boundaries under schedule 3, clause 17 of the Local Government Act 2002.

​

There are 67 territorial authorities: 12 city councils, 53 district councils, Auckland Council, and Chatham Islands Council. Five territorial authorities (Auckland Council, Nelson City Council, and the Gisborne, Tasman, and Marlborough district councils) also perform the functions of a regional council and are therefore unitary authorities. The Chatham Islands Council performs some regional council functions.

​

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. When defining the boundaries of territorial authorities, the Local Government Commission bases considerable weight on the ‘community of interest’.

​

Territorial authorities are defined at meshblock level. Statistical area 1, statistical area 2 and statistical area 3 geographies nest within territorial authority boundaries.

​

Maintenance

Local government boundaries may be changed through the Local Government Act 2002, an Act of Parliament, or a natural process such as the middle line of a river changing its natural course.

​

The Territorial Authority classification is released annually on 1 January to coincide with the update of meshblocks, but there are not always changes from the previous classification.

​

1989:

New Zealand’s local government structural arrangements were significantly reformed by the Local Government Commission in 1989. Prior to reformation there were 205 territorial local authorities: 28 cities, 78 boroughs, 67 counties, 31 districts, and 1 town district, as well as a multitude of ad-hoc authorities such as pest control boards, drainage boards, catchment boards, and domain and reserve boards.

​

These were replaced by 74 territorial local authorities, 15 of which were cities and 58 districts. The exception was Chatham Islands County which retained its county status.

​

1990:

Invercargill was proclaimed a city.

​

1992:

Nelson-Marlborough Regional Council was abolished by a Local Government Amendment Act. Kaikoura District was transferred to the Canterbury Region. Nelson City, and Tasman and Marlborough districts became unitary authorities.

​

1995:

The Chatham Islands County was dissolved and reconstituted by a specific Act of Parliament as the "Chatham Islands Territory", with powers similar to those of territorial authorities and some functions similar to those of a regional council. This included the addition of territorial sea, a coastal buffer extending to twelve nautical miles from the coastline.

​

1995:

Tasman District boundary extended to align with the Tasman Region boundary at the 12-mile limit.

​

1998:

Not Applicable category changed to Area Outside Territorial Authority

​

2004:

Tauranga District changed to Tauranga City.2006:Banks Peninsula District merged into Christchurch City as a result of a Local Government Commission decision following a 2005 referendum.

​

2010:

Auckland Council established under the Local Government (Tamaki Makaurau Reorganisation) Act 2009. Rodney District, North Shore City, Waitakere City, Auckland City, Manukau City, Papakura District, and Franklin District territorial councils, and the Auckland Regional Council, were abolished to become a unitary authority known as the Auckland Council. The area now consists of one city council (with statutory provision for three Māori councillors), 13 wards, and 21 local boards.

​

2015:

Wanganui District Council name changed to Whanganui District Council effective 1 December 2015.

​

2020:

Otorohanga District Council name amended to Ōtorohanga District Council.

​

Both changes were under schedule 2 of the Local Government Act 2002 and effective 17 January 2020.

​

2021:

A local government reorganisation transferred land between two territorial authorities, Western Bay of Plenty District and Tauranga City. The changes took effect on 19 February 2021 under schedule 3 of the Local Government Act 2002. Refer to the New Zealand Gazette notice for further details.

Lidar was captured for Auckland Council by NZ Aerial Mapping & Aerial Surveys Limited. The capture of the data commenced on 17th July and was completed by the 23 November 2013. The datasets were generated by both ASL and NZAM. All raw point cloud data was produced by NZAM & ASL prior to data being sent to Genesys International for the data classification and product generation. The survey area includes the Auckland city urban area and adjacent rural land. Data management and distribution external to Auckland Council is managed by Land Information New Zealand. Prepared DEM and DSM files are available through the LINZ Data Service https://data.linz.govt.nz/layer/3405-auckland-lidar-1m-dem-2013/ https://data.linz.govt.nz/layer/3406-auckland-lidar-1m-dsm-2013/

For CSV and Excel extracts, the Ecosystem Extent Domains document will assist in resolving domains. This layer has been created to assist the Council in identifying and managing threatened and at risk ecosystems in the Auckland region. The ecosystem classification system used in creating this layer was developed by the Department of Conservation (Singers & Rogers 2014) and refined by Nick Singers to match the specific nature of ecosystems found within the Auckland Region. For further information about the classification system, see Singers et al. (2015) Indigenous terrestrial and freshwater ecosystems of Auckland. The process of mapping the current extent of Auckland’s terrestrial and freshwater ecosystems has involved collating data and information from a variety of sources. For example, all terrestrial ecosystem data from past ecological surveys, held by legacy councils, was aggregated; numerous publications that documented the state of indigenous vegetation in Auckland were collated, including the Department of Conservation’s Protected Natural Area Programme survey reports and research papers for sites throughout the region. Ecological surveys carried out to potential SEAs assisted in filling knowledge gaps and to updating some of the existing data. The resulting data was used to inform the mapping of ecosystems. For further information on the ecosystems in the Auckland Region refer to:Singers, N.; Osborne, B.; Lovegrove, T.; Jamieson, A.; Boow, J.; Sawyer, J.; Hill, K.; Andrews, J.; Hill, S.; Webb, C. 2016.

**Territorial authorities **

Territorial Authority Local Board (TALB) is a derived classification. TALB is derived from the definitive version of the annually released local boards for Auckland and territorial authorities for the rest of New Zealand as at 1 January 2023, as defined by the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian). This version contains 21 local boards in the Auckland Council and 66 territorial authority boundaries for the rest New Zealand.

​

Territorial authorities are the second tier of local government in New Zealand, below regional councils. They are defined under schedule 2, part 1 of the Local Government Act 2002 as city councils or district councils. Territorial authorities were established in 1989 when 205 territorial local authorities were replaced by 75 territorial authorities. Territorial boundaries must coincide with meshblock boundaries under schedule 3, clause 17 of the Local Government Act 2002.

​

Local boards

Local boards share governance with a council’s governing body and each has complementary responsibilities, guaranteed by legislation. Local boards can propose bylaws and they gather community views on local and regional matters. Legislation enacted in 2012 allows for the establishment of local boards in areas of new unitary authorities that are predominantly urban and have a population of more than 400,000. The boundaries of local boards cannot be abolished or changed except through a reorganisation process. If new local boards are created they will be incorporated into this classification.

​

Local boards are defined at meshblock level. Stats NZ must be consulted if there is a proposed boundary change that does not align with the meshblock pattern. Local boards do not coincide with the statistical area 1 (SA1) or statistical area 2 (SA2) geographies.

​

Auckland Council local boards

The Auckland Council was established in November 2010 under the Local Government (Tamaki Makaurau Reorganisation) Act 2009. Seven territorial authorities within the Auckland Region were abolished and replaced by the unitary authority Auckland Council. Local boards fall within the community board classification. Changes were reflected in the 2011 and subsequent community board classifications.

​

For statistical outputs that use territorial authorities to aggregate and report data Auckland Council is treated as a single geographic entity, whereas previously data was provided for the seven territorial authorities. Presenting data for this single territorial authority hides meaningful patterns and trends for a significant portion of the population. A solution was to create a new classification of territorial authorities that includes the local boards for Auckland.

​

Numbering

TALB is a flat classification. Each category has a unique five-digit code. The first three digits represent the territorial authority code, ranging from 001 to 076 (with 999 being Area Outside Territorial Authority). The last two digits indicate if the territorial authority is further defined at local board level: 00 indicates the territorial authority is “not further defined”. Auckland retains sequential codes from the community board classification. The names for the classification are retained from the territorial authority and community board classifications.

Predicted natural flow path of water over the ground when the stormwater network is overloaded. This layer is a dissolved version of the OverlandFlowPaths layer where each segment is classified by its upstream catchment area, which will fall into one of the following ranges:2000-4000 m24000 m2 to 1 Ha1–3 Ha3–100 Ha>100 HaThe layer is an update of an existing layer and was created by WSP Opus in 2019.LineageThe OverlandFlowPaths layer is based on Auckland Council’s latest LiDAR data, which was flown in 2016 and became available after processing in 2018. The 2016 LiDAR data had a much higher point density (4 points per m2) than previous versions, which should result in more accurate flow paths. The layer was generated using the D8 flow model algorithm in ArcGIS.
