Nationwide unadjusted Statistics NZ figures showed a record net gain of 59,600 migrants in the July 2015 year. The annual gain in migrants has been setting new records for the past 12 months.
The increased net gain of migrants in the July 2015 year was driven by more arrivals and fewer departures. Migrant arrivals (117,100) continued to reach a new high, up 14 per cent from the July 2014 year.
Migrant departures numbered 57,500, down 6 per cent.
The increase in migrant arrivals between the July 2014 and July 2015 years was led by India, Australia, the Philippines and China. The increase in arrivals from Australia involved New Zealand citizens and non-New Zealand citizens.
The fall in migrant departures was mainly due to fewer New Zealand citizens leaving for Australia.
