Our take on the latest National population estimates (Tue 18 May 2021)
Total NZ population estimate
5,116,350
As at March 2021
Population growth slows to 0.7%pa
Annual net migration down to 6,561
The key numbers...
- New Zealand’s resident population is estimated to have grown by just 0.7% since March 2020, with data now showing an entire year of closed borders and minimal migration. This population growth rate is the slowest since the end of 2012.
- Annual net migration has plunged in the last quarter, from 41,100 in December 2020, to 6,500 in March 2021. As the large increase in migrants coming into New Zealand before COVID-19 moves out of the annual numbers, net migration has now collapsed by 93%.
- For the first time since 2014, natural increase (births minus deaths) is now the biggest contributor to population growth after the dramatic slowdown in annual net migration.
- The Level 4 lockdown doesn’t seem to have significantly increased the number of births in the March 2021 quarter, with the population aged under 15 years of age remains flat.

...and our reaction
- As the boom of migrants at the beginning of 2020 moves out of the numbers, annual net migration has dropped to very low levels. With closed borders, and indication of a slow and cautious approach to reopening, we don’t expect net migration to pick up significantly before 2023.
- Skilled labour remains a major concern for many businesses, particularly in the construction industry, especially as consents reach record highs. With next to no migration and almost no growth in the working age population, these capacity constraints are likely to remain.
- Over time, lower trend net migration will limit additional demand for housing, and in part drives our expectations for slower house price growth in future years.
- The much-anticipated immigration speech by Economic Development Minister Stuart Nash (in Immigration Minister Kris Faafoi’s absence) failed to deliver any meaningful new announcements or changes to migration settings and therefore does not change our expectations on migration or population growth going forward at present.
