E ngā mana, e ngā reo i tuku kōrero mai mō te rangahau o te oranga Māori e kīia nei ko Te Kupenga 2013 tēnā me hoki kōrero atu ki a koutou mō ngā āhuatanga a tō iwi. Heoi anō, tēnā koutou e tautoko mai te kaupapa nui nei.

To all those people of Māori descent who completed the Te Kupenga 2013 survey of Māori well-being, we return to you information about your iwi. Thank you for your support.

New tool shows information available

We’ve a new interactive data tool that looks at four cultural well-being measures for all iwi with respondents in Te Kupenga 2013. Most of the statistics were produced using a methodology called small domain estimation. We used this technique because most iwi did not have enough respondents in Te Kupenga to use our standard methodology.

The measures available are:

  • te reo Māori proficiency
  • importance of involvement in Māori culture
  • visited ancestral marae in the last 12 months
  • ease of getting help with Māori cultural practices.

See Iwi cultural well-being from Te Kupenga 2013, the interactive iwi data tool (with downloadable graphs and tables) on our new innovation website. The innovation site is a place for you to explore and provide feedback to us at Statistics NZ as we experiment with new ideas and initiatives.

The tool is housed on the innovation site initially to test its usability and to get customer feedback. Based on customer feedback a version of this tool may be developed for the main Stats NZ website.

About small domain estimation

Small domain estimation uses a statistical model that allows us to produce statistics for small groups (domains) in a survey. Information about small groups is usually too unreliable to publish when using Statistics NZ’s standard methods.

‘Small domain’ refers to a particular demographic (eg an iwi) within a larger group. The sample size in a small domain may be too small to generate accurate estimates directly from the data. We therefore use additional data, such as census information, to provide statistically sound estimates.

Te Kupenga small domain estimation for iwi

We used two information sources to create these iwi statistics.
• Te Kupenga – contains many variables but it surveyed only 5,500 people. It doesn’t have enough respondents from some iwi to give reliable estimates.
• 2013 Census – includes New Zealand’s population and the number of people in each iwi, including their age, sex, and whether they can hold an everyday conversation in te reo Māori. The census can produce estimates for small groups, but doesn’t contain details about topics available in Te Kupenga.

We combined Te Kupenga and census data using a statistical model – to produce estimates for smaller iwi (those with 1–180 respondents in Te Kupenga).

Other information

See Iwi estimates using small domain estimation – technical documentation for further details on the statistical model we used to produce the estimates.

Download the information for all iwi in a csv file from Te Kupenga iwi estimates – metadata for csv file.

A wider range of information is available for some iwi (those with over 180 respondents in Te Kupenga), using direct estimates from the survey. See Iwi statistics from Te Kupenga.
