More passengers are passing through Auckland Airport, led by tourists from China and the United States.
The country's main gateway said patronage rose 7 percent to 592,911 people in June, compared with the same period a year ago.
Travellers from China and United States jumped last month.
Auckland Airport said passenger numbers from China jumped by more than a quarter, while those from the US rose by a fifth.
That offsets a fall in patronage from Britain.
On an annual basis, passenger growth rose 6 percent.
Analysts said a lower dollar would make New Zealand more attractive as a travel destination, particularly to the fast growing Asian tourist market.
Some Chinese airlines were already planning to lift capacity to New Zealand to meet demand.
