Iwi affiliation

The census is the only source of comprehensive iwi information. Iwi listed as part of the Iwi classification can get comprehensive information regarding their people, at highly detailed levels . Iwi use the classification to formalise their iwi status, as it is used as the source of official statistics on iwi population numbers for Treaty claims and public policy.

The 2009 iwi classification update working group noted several issues with the iwi classification review process, and with the guidelines for inclusion that are part of the iwi statistical standard (Iwi classification). Statistics NZ experienced some negative reaction following a review process. The 2009 working group recommended that the statistical standard and classification be reviewed before the 2018 Census.

Our current recommendations relating to iwi affiliation

• We recommend that iwi affiliation is included in the 2018 Census. However, the iwi affiliation question, iwi statistical standard – including guidelines for inclusion in the iwi classification – and the iwi classification itself may change depending on the outcomes of a review of the statistical standard for iwi. This review is in the initial stages but is planned to be completed in time for the development of the 2018 Census content.
