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.

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

This dataset is the definitive set of annually released boundries of local boards for Auckland and territorial authorities for the rest of New Zealand for 2022, 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. This version contains 21 local boards in the Auckland Council and 66 territorial authority boundaries for the rest New Zealand.

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 classification.

Levels 21 - 23 (1:282 - 1:71)Aerial Imagery 24-25 Color Infrared covers aerial images for the Auckland Region in color infrared. Infrared aerial photography involves capturing images using infrared light, which is outside the visible spectrum. This type of photography is useful for a variety of applications, including environmental monitoring, agriculture, and land management. Infrared imagery can reveal details not visible to the naked eye, such as vegetation health, water stress, and temperature variations, making it valuable for assessing plant vitality, detecting heat sources, identifying areas of moisture, and infrastructure conditions, making it invaluable for environmental monitoring and urban planning.Data Acquisition:• Phase 1: Aerial photography was captured over the Auckland region and the Hunua Ranges covering approximately 2,051 km². The data was captured between September 2023 – April 2024.• Phase 2: Aerial photography was captured over the Auckland District, covering approximately 1,949 km². The data was captured between September 2023 – April 2024.• Phase 3: Aerial photography was captured for the Auckland District covering approximately 2,129 km². Data capture took place between March 2024 – April 2025.

Please contact us at gis@aklc.govt.nz to request the four-band imagery.The remaining areas that are not part of this product have been captured in 2025 and will be added to this service by end of 2025. Map Projection All 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).EquipmentThe majority of the photography was captured using Vexcel's digital UltraCam Eagle Mark 3 (UCE-3) 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. This camera was fitted to a GSM 3000 gyro-stabilised mount and IGI AEROcontrol GNSS/IMU positioning system. Some portions were flown using Vexcel's digital UltraCam Lp (UCLp) camera fitted with the 70 mm lens and flown at an altitude of approximately 2,952 ft (900m).Sun Angle Imagery 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 32 to 59 degrees.Urban Building Displacement Specification Urban 0.075 m GSD imagery using the UCE-3 camera 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 is 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 Control A combination of existing control and LINZ benchmarks were observed for use with the aerial triangulation and bundle adjustment.DTM for Ortho Production The 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 set of annually released territorial authority boundaries for 2022 as defined the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian). This version contains 68 features.

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. Territorial authorities are the second tier of local government in New Zealand, below regional councils. The 67 territorial authorities comprise 13 city councils including the Auckland council, 53 district councils, and the Chatham Islands Territory.

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

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.

Merge of Department of Statistics Meshblock Level 1 boundaries and Topo Coastline, plus Chatham Islands to give a better map of the land area for each Territorial Local Authority (TLA). Unitary Authorities are also clipped for their TLA role. TLA boundaries are MHWS which is not mapped in the Cadastral database and is only approximate using the 1:50,000 coastline and island borders, but it is better than the generalised meshblocks. Reloaded to fix topology error that merged Kapiti and Porirua.

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.

​

Opotiki District Council name amended to Ōpōtiki 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.

​

Numbering

The territorial authority classification is a flat classification. Territorial authorities are given a unique three-digit code. The classification contains 68 categories (including ‘999 – Area Outside Territorial Authority’).

Auckland Urban Heat Assessment provides a highly detailed map of how temperatures vary across Auckland and the factors influencing these temperatures. Temperature predictions were generated using climate modelling tools, data from local climate monitoring stations, high resolution land cover data, and census data. The dataset was generated over a five-month period from 1stNovember 2021 to 31stMarch 2022, which coincided with Auckland's hottest summer on record.The datasets are useful to support communication on heat-related hazards and to inform decision making and planning for future heat impacts. The data is also useful to find synergies in heat and carbon mitigation solutions and to inform climate change risk assessment for Auckland.Further details on methods and findings are available in the technical report on Knowledge Auckland:https://www.knowledgeauckland.org.nz/publications/auckland-uban-heat-assessment-technical-report/The Urban Heat Datasets were produced for Auckland Council by Arup New Zealand Limited.Creation Date: October 2024Update Cycle: AdhocContact Person:Ayushi KachharaSenior Climate Analyst, Chief Sustainability OfficeAuckland Council
