Data on Iwi affiliation is best collected through a self–completion questionnaire or in a face–to–face interview. Unless interviewers are fluent speakers in te reo Māori collecting information by telephone is likely to be difficult.
Nineteen percent of respondents to the 1996 Census of Population and Dwellings Iwi question stated that they did not know the name of their Iwi so providing a tick box for this option will speed processing.
As some Iwi names are common to more than one region, to enable the correct Iwi code to be assigned, information must be sought on both the Iwi and the region where the Iwi is tangata whenua.
Sufficient room must be provided on the questionnaire for respondents to be able to supply both the Iwi name and the region.
The questionnaire module below is an example that meets the requirements documented in this statistical standard. Other questionnaire modules may vary in format but should conform to the requirements contained in this statistical standard.
