This dataset is the definitive version of the annually released regional council boundaries as at 1 January 2025, as defined by the regional councils and/or Local Government Commission and maintained by Stats NZ. This version contains 16 regional councils and area outside region (Chatham Islands Territory).

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.

Guide for Council District Map

This dataset represents the local legislative boundaries of the Lexington-Fayette Urban County Council. The Council districts are determined by the Fayette County Board of Election's voting precinct boundaries and 2020 Census demographic data. Voting precincts are grouped together to create the districts. Updates are made by Lexington-Fayette Urban County Government ordinance approximately every 10 years as new Census data is released in an attempt for population equality in the districts. The districts in this dataset were defined during a series of public meetings held by a Redistricting Committee consisting of 15 appointed members (one community member appointed by each sitting Council Member) and assisted by Lexington-Fayette Urban County Government GIS, Council, and Planning staff as well as the Fayette County Board of Elections. The ordinance for the Council Districts in this dataset received second reading by the Urban County Council on December 7, 2021.

This dataset is the definitive set of territorial authority boundaries as at 1 January 2025 as defined by the Local Government Commission and/or the territorial authorities themselves but maintained by Stats NZ, clipped to the coastline. This clipped version has been created for cartographic purposes and so does not fully represent the official full extent boundaries. 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

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:

Ōtorohanga 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.

2023:

A local government reorganisation transferred land between two territorial authorities, Whakatane District and Kawerau District. The changes took effect on 1 September 2024 under schedule 3 of the Local Government Act 2002. Refer to the New Zealand Gazette notice for further details.

This dataset is the definitive set of annually released regional council boundaries for 2022 as defined by the regional councils and/or Local Government Commission and maintained by Stats NZ (the custodian).

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 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.

The seaward boundary of any coastal regional council is the twelve-mile New Zealand territorial limit. Regional councils are defined at meshblock level. Statistical area 1 and statistical area 2 geographies nest within regional council boundaries.

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.

Following each census, Detroit City Council is required by the 2012 Detroit City Charter to redraw the boundaries of the City's seven non at-large districts to be "as nearly of equal population as practicable, contiguous, compact and in accordance with any other criteria permitted by law" (Sec. 3-108). After considering six district boundary proposals meant to meet these criteria, City Council selected the boundaries described in this document by an 8-1 vote on February 6, 2024. These boundaries will be used to determine resident districts when voting in 2025 municipal elections, and will officially take effect January 1, 2026.
