Te Kupenga iwi estimates – metadata for CSV file

See Downloads on Iwi cultural well-being from Te Kupenga 2013 for csv tables that contain iwi-level estimates produced using Te Kupenga 2013 survey.

The file is comma separated.

Information for opening the file in Microsoft Excel to read macrons

Some variables and variable names contain unicode text in order to produce macrons in te reo text. These are encoded using UTF-8. If you are opening the file in Microsoft Excel follow these steps to view the information correctly:

  1. Save the CSV file.
  2. Open Excel. 
  3. Import the data using Data-->Get External Data --> From text. 
  4. Browse to your file and select it.
  5. In the import wizard, choose ‘Delimited’ as the file type and change the File Origin to "65001 UTF" (or choose correct language character identifier).
  6. Change the Delimiter to comma.
  7. Select where to import to and Finish.


The file contains the following variables:

  • roheDesc – text description of the rohe associated with the iwi
  • iwiCode – iwi classification number
  • iwiDesc – text description of the iwi
  • measure – One of four selected measures/variables for which iwi estimates have been produced
  • measureTeReo – Te reo version of measure
  • responseDesc – Text description of the response option selected
  • responseDescTeReo – Te reo version of responseDesc
  • response – Numeric coding of the response option selected
  • methodology – either SDE (estimate produced using small domain estimation) or survey estimate (produced using Statistics NZ’s standard survey estimation methodology)
  • estimate – estimate
  • lowerConfidenceInterval – estimate of the lower 95% confidence interval
  • upperConfidenceInterval – estimate of the upper 95% confidence interval.

The file contains one row per iwi, measure, response combination.


The estimates are for the usually resident Māori population of New Zealand, living in occupied private dwellings on 2013 Census night, aged 15 years and over, and who identified themselves as having Māori ethnicity or Māori descent.

The iwi estimates include all people of Māori descent who gave that iwi as their iwi, or one of several iwi, in the 2013 Census.

The confidence intervals give the range in which we are 95 percent confident that the true population value falls.
