Key: How NZ's immigration works
Prime Minister John Key explains the current situation with NZ's immigration. The immigration surge continued to gather pace last month, with the net inflow of 4270 people the second-largest monthly gain on record. The rising trend has been driven by fewer New Zealanders leaving for Australia and more returning. The net loss of people to Australia last month would have fitted in a single airport bus - just 20, seasonally adjusted, compared with a net loss of 1550 in June last year.
