What is internal migration?

This summary reports on migration out of and into Tāmaki Makaurau/Auckland to other parts of New Zealand between the 2018 and 2023 Census, based on the 2023 Census question on where residents were living five years earlier. The analysis only includes people who were usually resident in New Zealand at both the 2018 and 2023 Census. It does not report on movements within Auckland, or to and from overseas, and does not include those who were not (yet) born in 2018.

Overall net loss to other parts of New Zealand

More than 136,000 people who lived in Auckland in 2018 had moved to another part of New Zealand by 2023. Meanwhile, around 85,000 people who lived in other parts of New Zealand in 2018 had moved to Auckland by 2023. This constitutes a net loss overall of over 50,000 people.
