2018 Iwi affiliation estimated counts


Estimated iwi affiliation counts based on the 2018 Census


In April 2019 Stats NZ announced that it would not release official statistical counts of iwi due to the number of census records missing iwi affiliation data and the lack of alternative government data sources to fill the gaps. Since then, Stats NZ and iwi data technicians from the Data Iwi Leaders Group (Data ILG) have looked at methods to reduce the impact of missing iwi data. This work has led to the release of the 2018 iwi estimates on Te Whata and on the Stats NZ website at Iwi affiliation (estimated counts): 2018

For many purposes, the 2018 iwi estimates provide a more relevant and up-to-date picture than continued use of 2013 Census iwi data. These iwi estimates are not official 2018 Census counts and the quality of these estimates ranges from moderate to poor depending on how the data is used.
