Data is available by statistical area 2.

    Māori descent indicator categories are:

    • Māori descent
    • No Māori descent
    • Don’t know

    Map shows the percentage change in the Māori descent census usually resident population count between the 2018 and 2023 Censuses.

    Te Whata

    Under the Mana Ōrite Relationship Agreement, Te Kāhui Raraunga (TKR) will be publishing Māori descent and iwi affiliation data from the 2023 Census in partnership with Stats NZ. This will be available on Te Whata, a TKR platform.

    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.

    Description

    This dataset contains counts of people of Maori descent by the official language indicator from the 2013 Census. The data is presented at meshblock level and uses the 2013 Census boundaries. The variables provided are as follows:

    • Number of Maori Descent who speak te reo Maori
    • Number of Maori Descent who do not speak te reo Maori (includes no language)

    This dataset allows for the comparison across areas to determine the strength or otherwise of te reo Maori language for people of Maori descent.

    Notes: Confidentiality rules have been applied to all cells in this table, including randomly rounding to base 3. Unrounded counts of less than 6 have been confidentialised. Individual figures may not add up to totals, and values for the same data may vary in different tables. -999 indicates cells have been suppressed for confidentiality reasons

    Description

    This dataset contains information on:

    · Estimated resident population (ERP) at 30 June 1996, 2001, 2006, 2013, and 2018 for total population

    · ERP at 30 June 2018 by ethnic groups (European or Other (including New Zealander), Māori, Pacific, Asian, and Middle Eastern/Latin American/African) – estimates and percentage

    · Sex ratio – number of males per 100 females

    · ERP at 30 June 2018 by broad age groups and median age

    · Geographies available are regional council areas, territorial authority and Auckland local board areas, Statistical Area 2, and urban rural.

    Note: The geography corresponds to 2020 boundaries

    Note: -999 indicates data are not available.

    About the estimated resident population

    The estimated resident population at 30 June in the census year is based on the census usually resident population count, with updates for:

    · net census undercount (as measured by a post-enumeration survey)

    · residents temporarily overseas on census night

    · births, deaths and net migration between census night and 30 June

    · reconciliation with demographic estimates at the youngest ages.

    The estimated resident population is not directly comparable with the census usually resident population count because of these adjustments.

    For more detailed information about the methods used to calculate each base population, see DataInfo+ Demographic estimates.

    Ethnic groups

    It is important to note that these ethnic groups are not mutually exclusive because people can and do identify with more than one ethnicity. People who identify with more than one ethnicity have been included in each ethnic group.

    The 'Māori', 'Pacific', 'Asian' and 'Middle Eastern/Latin American/African' ethnic groups are defined in level 1 of the Ethnicity New Zealand Standard Classification 2005. The estimates for the 'European or Other (including New Zealander)' group include people who belong to the 'European' or 'Other ethnicity' groups defined in level 1 of the standard classification. If a person belongs to both the 'European' and 'Other ethnicity' groups they have only been counted once. Almost all people in the 'Other ethnicity' group belong to the 'New Zealander' sub-group.

    Time series

    This time series is irregular. Because the 2011 Census was cancelled after the Canterbury earthquake on 22 February 2011, the gap between the 2006-base and 2013-base estimated resident population is seven years. The change in data between 2006 and 2013 may be greater than in the usual five-year gap between censuses. Be careful when comparing trends.

    Rounding

    Individual figures may not sum to stated totals due to rounding.

    More information

    See Estimated resident population (2018-base): At 30 June 2018 for commentary about the 2018 ERP.

    Description

    This dataset is the definitive version of the annually released Māori ward boundaries as at 1 January 2023 as defined by the territorial authorities and/or Local Government Commission, and maintained by Stats NZ (the custodian). In 2023, there are 34 Māori wards (excluding Area Outside Māori Ward) within 29 territorial authorities.

    The Local Electoral Act 2001 provides that Māori wards may be established in territorial authorities. If a territorial authority decides to have Māori wards, the wards within the council are known as general wards and Māori wards.

    The first Māori ward was established by representation review in 2019 and first appeared in the 2020 geographic boundaries released by Stats NZ. Changes to government legislation that allowed councils to decide on whether to include Māori wards in their arrangements resulted in 33 new Māori wards being added to the 2023 classification.

    Māori ward boundaries are defined at meshblock level.

    **Numbering **

    Māori wards are numbered based on their corresponding territorial authority. Each Māori ward has a unique five-digit code. The first three digits represent the territorial authority that the Māori ward lies within. The following two digits are sequential and represent the number of Māori wards within a territorial authority.

    Territorial authorities that do not have Māori wards use “99” at the end of the Māori ward code, and the descriptor “Area Outside Māori Ward”.

    There is also a code of 99999 for those areas outside of territorial authority areas.

    Generalised version

    This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

    Macrons

    Names are provided with and without tohutō/macrons. The column name for those without macrons is suffixed ‘ascii’.

    Digital data

    Digital boundary data became freely available on 1 July 2007.

Area covered
Description

Dataset contains Māori descent indicator census usually resident population counts from the 2013, 2018, and 2023 Censuses, as well as the percentage change in the Māori descent indicator counts between the 2013 and 2018 Censuses, and between the 2018 and 2023 Censuses. Data is available by statistical area 2.

Māori descent indicator categories are:

  • Māori descent
  • No Māori descent
  • Don’t know

Map shows the percentage change in the Māori descent census usually resident population count between the 2018 and 2023 Censuses.

Footnotes

Te Whata

Under the Mana Ōrite Relationship Agreement, Te Kāhui Raraunga (TKR) will be publishing Māori descent and iwi affiliation data from the 2023 Census in partnership with Stats NZ. This will be available on Te Whata, a TKR platform.

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.
