Boundaries of Iwi rohe, location of Marae and statutory acknowledgement areas within the Taranaki region.A statutory acknowledgement is a formal acknowledgement by the Crown of the mana of tangata whenua over a specified area. It recognizes the particular cultural, spiritual, historical and traditional association of an iwi with a site, which is identified as a statutory area. Statutory areas only relate to Crown‐owned land and include areas of land, geographic features, lakes, rivers, wetlands as well as coastal marine areas.

These boundaries comprise the proposed seven Māori electorates released by the Representation Commission in March 2025 for public consultation. Written objections to the proposed electorate boundaries can be made between 25 March and 27 April 2025. Refer here for more information about having your say.

​

The Representation Commission is convened by the Surveyor-General, its role is to re-draw electorate boundaries to make sure each electorate has about the same number of people. Stats NZ calculates the Māori electoral population, number of Māori electorates and electoral quota using the formula specified in the Electoral Act 1993. When setting the boundaries, the Representation Commission also considers existing boundaries, communities of interest (including iwi affiliations), the infrastructure that links communities (such as main roads), topographical features, and any projected variation in the population of those electorates during their existence.

​

Data is provided with tohutō/macrons (UTF-8 format). To support users with the compatibility of the data and the applications they might be using, additional fields are also provided in ASCII format.

​

The electoral populations are calculated from the 2023 Census data using the formulae specified in the Electoral Act 1993 and are confidentialised using Stats NZ confidentiality rules. The rules applied to the electoral populations are suppression of all unrounded counts below six (displayed as: ‘-999’) and random rounding to base three. There may be slight differences when comparing the total electoral population for electorates to totals derived using electoral population counts at meshblock level or another source.

​

In a small number of cases, the proposed electorate boundaries do not align to the annual 2025 meshblock boundaries exactly. This is due to meshblock adjustments that have been made as part of the Representation Commission’s process. Apart from these adjustments, a meshblock freeze remains in place until the Representation Commission has finished its electorate boundary review and the new electorate boundaries have been set.

Geographical boundaries

Statistical standard for geographic areas 2023 (updated December 2023) has information about geographic boundaries as of 1 January 2023. Address data from 2013 and 2018 Censuses was updated to be consistent with the 2023 areas. Due to the changes in area boundaries and coding methodologies, 2013 and 2018 counts published in 2023 may be slightly different to those published in 2013 or 2018.

​

Subnational census usually resident population

The census usually resident population count of an area (subnational count) is a count of all people who usually live in that area and were present in New Zealand on census night. It excludes visitors from overseas, visitors from elsewhere in New Zealand, and residents temporarily overseas on census night. For example, a person who usually lives in Christchurch city and is visiting Wellington city on census night will be included in the census usually resident population count of Christchurch city.

​

Caution using time series

Time series data should be interpreted with care due to changes in census methodology and differences in response rates between censuses. The 2023 and 2018 Censuses used a combined census methodology (using census responses and administrative data), while the 2013 Census used a full-field enumeration methodology (with no use of administrative data).

​

About the 2023 Census dataset

For information on the 2023 dataset see Using a combined census model for the 2023 Census. We combined data from the census forms with administrative data to create the 2023 Census dataset, which meets Stats NZ's quality criteria for population structure information. We added real data about real people to the dataset where we were confident the people who hadn’t completed a census form (which is known as admin enumeration) will be counted. We also used data from the 2018 and 2013 Censuses, administrative data sources, and statistical imputation methods to fill in some missing characteristics of people and dwellings.

​

Data quality

The quality of data in the 2023 Census is assessed using the quality rating scale and the quality assurance framework to determine whether data is fit for purpose and suitable for release. Data quality assurance in the 2023 Census has more information.

​

Quality rating of a variable

The quality rating of a variable provides an overall evaluation of data quality for that variable, usually at the highest levels of classification. The quality ratings shown are for the 2023 Census unless stated. There is variability in the quality of data at smaller geographies. Data quality may also vary between censuses, for subpopulations, or when cross tabulated with other variables or at lower levels of the classification. Data quality ratings for 2023 Census variables has more information on quality ratings by variable.

​

Māori descent concept quality rating

Māori descent is rated as very high quality.

Māori descent – 2023 Census: Information by concept has more information, for example, definitions and data quality.

​

Using data for good

Stats NZ expects that, when working with census data, it is done so with a positive purpose, as outlined in the Māori Data Governance Model (Data Iwi Leaders Group, 2023). This model states that "data should support transformative outcomes and should uplift and strengthen our relationships with each other and with our environments. The avoidance of harm is the minimum expectation for data use. Māori data should also contribute to iwi and hapū tino rangatiratanga”.

​

Confidentiality

The 2023 Census confidentiality rules have been applied to 2013, 2018, and 2023 data. These rules protect the confidentiality of individuals, families, households, dwellings, and undertakings in 2023 Census data. Counts are calculated using fixed random rounding to base 3 (FRR3) and suppression of ‘sensitive’ counts less than six, where tables report multiple geographic variables and/or small populations. Individual figures may not always sum to stated totals. Applying confidentiality rules to 2023 Census data and summary of changes since 2018 and 2013 Censuses has more information about 2023 Census confidentiality rules.

The 2023 and 2018 Censuses used a combined census methodology (using census responses and administrative data), while the 2013 Census used a full-field enumeration methodology (with no use of administrative data).

About the 2023 Census dataset

For information on the 2023 dataset see Using a combined census model for the 2023 Census. We combined data from the census forms with administrative data to create the 2023 Census dataset, which meets Stats NZ's quality criteria for population structure information. We added real data about real people to the dataset where we were confident the people who hadn’t completed a census form (which is known as admin enumeration) will be counted. We also used data from the 2018 and 2013 Censuses, administrative data sources, and statistical imputation methods to fill in some missing characteristics of people and dwellings.

​

Data quality

The quality of data in the 2023 Census is assessed using the quality rating scale and the quality assurance framework to determine whether data is fit for purpose and suitable for release. Data quality assurance in the 2023 Census has more information.

​

Quality rating of a variable

The quality rating of a variable provides an overall evaluation of data quality for that variable, usually at the highest levels of classification. The quality ratings shown are for the 2023 Census unless stated. There is variability in the quality of data at smaller geographies. Data quality may also vary between censuses, for subpopulations, or when cross tabulated with other variables or at lower levels of the classification. Data quality ratings for 2023 Census variables has more information on quality ratings by variable.

​

Age concept quality rating

Age is rated as very high quality.

Age – 2023 Census: Information by concept has more information, for example, definitions and data quality.

​

Using data for good

Stats NZ expects that, when working with census data, it is done so with a positive purpose, as outlined in the Māori Data Governance Model (Data Iwi Leaders Group, 2023). This model states that "data should support transformative outcomes and should uplift and strengthen our relationships with each other and with our environments. The avoidance of harm is the minimum expectation for data use. Māori data should also contribute to iwi and hapū tino rangatiratanga”.

Confidentiality

The 2023 Census confidentiality rules have been applied to 2013, 2018, and 2023 data. These rules protect the confidentiality of individuals, families, households, dwellings, and undertakings in 2023 Census data. Counts are calculated using fixed random rounding to base 3 (FRR3) and suppression of ‘sensitive’ counts less than six, where tables report multiple geographic variables and/or small populations. Individual figures may not always sum to stated totals. Applying confidentiality rules to 2023 Census data and summary of changes since 2018 and 2013 Censuses has more information about 2023 Census confidentiality rules.

Four Freshwater Management Units created from the NIWA REC Catchments: Taupo Gates to Karapiro. Karapiro to Ngaruawahia. Ngaruawahia to Port Waikato. Waipa River. These catchments encompass the area of the combined Healthy Rivers catchments. Used as the starting catchments for Healthy Rivers. The dataset includes boundary information for the Waikato and Waipa catchments that fall within the Waikato Regional Council legal boundaries or are covered by the RCP maps. This project is co-managed under the JMAs of Ngāti Maniapoto, Raukawa, Ngāti Tūwharetoa, Te Arawa River Iwi and Waikato-Tainui as at 12 February 2012.

The takutai moana legislation provides for recognition of customary interests of iwi, hapū and whānau in the common marine and coastal area of Aotearoa New Zealand and its offshore islands.The takutai moana legislation also provides for the right of all New Zealanders to access and use the common marine and coastal area (subject to any lawful restrictions, including for the protection of wāhi tapu and wāhi tapu areas).Applications had to be made by 3 April 2017 under te Takutai Moana Act 2011 and by 30 May 2021 under Ngā Rohe Moana o Ngā Hapū o Ngāti Porou Act 2019.Hon Andrew Little is the Minister responsible for the takutai moana legislation, and the Minister who can recognise customary marine title and protected customary rights on behalf of the Crown.The application areas described in the Crown Engagement layer are derived from maps and information provided to Te Arawhiti by applicants.A quality assessment of this layer was completed in late 2021. This QA ensured that descriptive information given by the applicant has been incorporated into application area boundaries. Some application boundaries will now differ from the original attached maps provided by applicants, given that further defining geographic information provided.An applicant may seek to refine their application area at any time. They must, however, submit an updated map and/or provide relevant geographical information. An updated map can be submitted by emailing Te Kāhui Takutai Moana at takutaimoana@tearawhiti.govt.nzThe landward boundary of all applications follows the New Zealand Coastline - Mean High Water Mark (Land Information New Zealand 2021) in the absence of a nationwide dataset for Mean High Water Springs.This data should not be considered a single point of truth. Application areas are indicative and only reflect what boundary information has been submitted by applicants.

Draft boundaries for Significant Natural Areas defined in the December 2016 report by Wildlands Ecologists. These boundaries were revised in July 2017 and are currently being updated as the Place Planning team carries out site visits to confirm the boundaries. SNAs are a natural ecosystem or habitat with significant indigenous biodiversity values. SNAs are identified by Wildlands Ecological Specialists against five criteria based on the Regional Policy Statement for Wellington Region. The criteria are: representativeness, rarity, diversity, ecological context, and tangata whenua values. We worked with ecologists and landscape specialists Wildlands and Boffa Miskell to map Wellington’s threatened indigenous flora and fauna based on Department of Conservation classification. We talked to local iwi about special landscapes. Policy 23 of the Regional Policy Statement for the Wellington region states ‘District and regional plans shall identify and evaluate indigenous ecosystems and habitats with significant indigenous biodiversity values; these ecosystems and habitats will be considered significant if they meet one or more of the following criteria: Representativeness: the ecosystems or habitats that are typical and characteristic examples of the full range of the original or current natural diversity of ecosystem and habitat types in a district or in the region, and: Are no longer commonplace (less than about 30 % remaining) Are poorly represented in existing protected areas (less than about 20 % legally protected) Rarity: the ecosystem or habitat has biological or physical features that are scarce or threatened in a local, regional, or national context. This can include individual species, rare and distinctive biological communities and physical features that are unusual or rare. Diversity: the ecosystem or habitat has a natural diversity of ecological units, ecosystems, species and physical features within an area Ecological context of an area: the ecosystem or habitat: Enhances connectivity or otherwise buffers representative, rare or diverse indigenous ecosystems and habitats, or Provides seasonal or core habitat for protected or threatened indigenous species Tangata Whenua Values: the ecosystem or habitat contains characteristics of special spiritual, historical or cultural significance to tangata whenua, identified in accordance with Tikanga Māori. In August 2019, the Place Planning team began engagement with members of the public whose property boundaries overlapped with an outstanding landscape boundary as part of the Backyard Taonga project. In March 2020, the Place Planning team began consultation on the Draft Spatial Plan as a precursor for a full District Plan review.
