He said the largest group of people leaving New Zealand were between the ages of 25 and 44, which was a concern for the labour market.
“If we take these figures alongside the age breakdown of migrants entering or leaving the country, it seems likely that much of the country is experiencing a relative drain of its workforce of 25- to 44-year-olds,” he said.
“And apart from a few urban areas and tourism-intensive hotspots, those losses are not being mitigated by an inflow of similarly aged people from overseas.”
Kiernan said it was also interesting to see an increase in the number of people over 55 leaving New Zealand, following a spike up in the Covid-19 years.
“It may well be that as conditions have changed and the world has settled down a bit, and our economy is slowing, that some of those people are heading back overseas again,” he said.
“There was some older people coming back in their sort of late 40s and early 50s, seeing some of those people leave again, that would match up with the previous flows that we’ve seen.”
