Stats NZ said the provisional net migration gain of 111,100 in the year comprised a net gain of 163,600 non-New Zealand citizens that more than offset the net migration loss of 52,500 Kiwi citizens.
For migrant arrivals in the March 2024 year, citizens of India were the largest group, with 49,800 arrivals.
About 31,900 Philippines citizens arrived. About 26,800 arrivals were citizens of China and 25,800 were New Zealand citizens.
The next largest groups by citizenship were from Fiji, South Africa, Sri Lanka and the UK.
“Country of citizenship is the nationality of passport used to arrive in or depart from New Zealand and is not necessarily the country of previous or next residence,” Stats NZ said.
For non-New Zealand citizens, the net migration gain of 163,600 in the year to March compared with a net migration gain of 105,000 in the March 2023 year.
It was well above the pre-Covid average for March years of 47,600.
For March this year compared with the same month in 2023, migrant arrivals were down 17 per cent and numbered 20,800.
Departures were up 98 per cent to 16,300.
An economist said many of the Kiwi citizens leaving were probably younger people with skills, trades and earning potential.
“Kiwis are not getting ahead and they’re looking offshore and thinking, ‘why not’?” ASB senior economist Mark Smith told the Herald.
“From an OE point of view, if you do have the skills in demand, you’ll probably go.”
The Stats NZ figures are provisional, meaning the agency does sometimes revise them later.
“They key stuff was the direction of the revision. In the past we’ve had the migration numbers revised up. Now they’re being revised down,” Smith said today.
Many of the departing citizens were probably heading to Australia and the UK, he said.
“All of these economies are facing similar challenges but arguably, they’re in a slightly [better] position than we are.”
Smith some of the departures were also due to pent-up demand for travel, which was suppressed for the first two years of the pandemic.
He expected net overall migration to cool from the latest figure of 111,100 to about 65,000 due to the sluggish New Zealand economy and a tightening of migration entry criteria.
This could impact the construction sector, especially residential construction, and the retailers selling consumer durable goods new migrants needed.
The loss of citizens was likely to have some corrosive effects on the economy, Smith said.
“You’re losing quite a lot of productive talent. New Zealand’s productivity track record has been abysmal since Covid.”
Smith said the latest migration data indicated a prolonged domestic economic slowdown.
Despite the generally grim prognosis, Smith said there was at least the prospect of the Reserve Bank cutting the Official Cash Rate sooner than expected.
