The net outflow of migrants continued in January, pushing the annual population loss from migration to 3100, its highest for more than 10 years.
Permanent and long-term departures exceeded arrivals by 650 in January, on a seasonally adjusted basis. That is a level exceeded only once (in September last year) since February 2001. The net flow has been negative for 10 of the past 12 months.
The loss over the past year compares with an average gain of 16,300 over the preceding 10 years.
In the year ended January there was a net loss of 38,100 people to Australia, the largest yet recorded, reflecting 51,900 departures offset by 13,800 arrivals, Statistics New Zealand said. In both directions most were New Zealand citizens. But economists noted that on a seasonally adjusted basis departures to Australia have been declining in recent months.
They were now at their lowest level since February last year, Infometrics economist Matt Nolan said, and had declined 13 per cent from their peak last September.
