There was a strong surge in population growth from migration in March, driven mainly by New Zealand citizens returning home as COVID-19 restrictions began to bite around the world, while fewer New Zealanders left the country to live overseas.
The latest figures from Statistics NZ show that 5784 NZ citizens returned to this country permanently or long term in March, more than double the 2181 that returned in March last year.
Conversely, just 1735 NZ citizens left the country long term in March, down from 3258 in March last year.
That provided a net gain of 4048 NZ citizens in March compared to a net loss of 1077 in March last year.
Migration of non-NZ citizens followed a different pattern, with arrivals and departures both down compared to a year ago.
There were 7436 non-NZ citizens who arrived long term in March, down from 8551 in March last year, while 3021 departed long term, compared to 3952 in March last year.
That gave an overall net gain of 4415 non-NZ citizens in March, down only slightly from 4599 in March last year.
Overall that meant there was a total net gain of 8463 people in March, more than double the March 2019 net gain of 3522.
However, Statistics NZ has warned that the latest figures are more uncertain than usual, due to COVID-19 travel restrictions in New Zealand and other countries, and may not be indicative of a long term trend.
"More New Zealand citizens than usual have migrated home, for a number of reasons, including possibly seeing New Zealand as a safe haven," Statistics NZ Population Insights Senior Manager Brooke Theyers said.
"At the same time, New Zealand citizens may have been unable or reluctant to head offshore."
Statistics NZ said the March figures were provisional, and were subject to revision, especially as some New Zealand citizens who recently returned may head back overseas once border restrictions were relaxed and international travel resumed.
