Iwi affiliation data released today by the Māori-designed platform Te Whata shows iwi populations have increased by an average of 46% during the last 10 years.
It is the first time census data has been released by an organisation before Stats NZ – part ofa partnership between Stats and the Data Iwi Leaders Group (Data ILG).
Lead technician for the Data Iwi Leaders Group Kirikowhai Mikaere said the data provides a more accurate insight than ever before.
“There has been an increase in all iwi affiliation populations, however, in addition to a real-world population increase, the numbers reflect the incorporation of additional data sources by way of the combined collection model, improvements in response rates for Māori, and changes to the question design and functionality online, meaning whānau Māori were able to more accurately and appropriately reflect their whakapapa.”

Which is the biggest iwi in Aotearoa?
Ngāpuhi retain the title of New Zealand’s largest iwi by a wide margin; 184,470 people whakapapa to the iwi, meaning just under a fifth of all people of Māori descent affiliate to Ngāpuhi.

Iwi populations are also youthful, with on average, 46.5% of individuals affiliated with an iwi being under the age of 25.
Data from the 2023 census showed the median age of the Māori population is 27.2 years, more than a decade younger than that of the total New Zealand population, which sits at 38.1 years.
