Population growth from migration is continuing to increase with a net population gain 69,090 in the year to June.

That compares with a net gain of 58,259 in the year to June 2015 and 38,338 in the year to June 2014, according to Statistics NZ.

The latest figures show that population growth from migration is continuing to increase, both on an annual and monthly basis, although the rate of increase is slowing.

If present trends continue it is likely that net migration will probably peak somewhere just over 70,000 a year in the next few months.

In the year to June there were 125,055 people who arrived in this country on a permanent or long term basis and and 55,965 who left permanently or long term, giving the net gain of 69,090.

Of the 125,055 new arrivals, 30,759 were New Zealand citizens returning home and 94,296 were non-New Zealand citizens.

Of the 55,965 long term departures, 33,898 were New Zealand citizens and 22,067 were non-New Zealand citizens.

India was the biggest source of new migrants with a net gain of 12,031 people from that country in the year to June, followed by 10,433 from China and Hong Kong, 5010 from the Philippines, 4263 from the UK, 3125 from France, 3054 from South Africa and 3044 from Germany.

There was also a net gain of 1933 people from Australia in the year to June.

In a First Impressions note on latest figures Westpac senior economist Anne Boniface said June may have been the month that migration peaked and it may start to fall back.

"There has been a gradual slowing in arrivals of non-new Zealanders over the last year, which continued this month [June], while departures of New Zealanders ticked higher in June," she said.

"We expect annual net migration to fall over the coming years, as foreigners who arrived on temporary work or student visas over the past three years begin to depart, and as the recovering Australian labour market begins to attract New Zealanders across the Tasman."
