An increase in inflows of migrants would also maintain pressure on the housing market, where issues of limited housing supply were "already starting to bite."
The New Zealand tourism industry would be pleased with the stabilisation in visitor arrivals numbers this year, with June result particularly strong, said Smith. New Zealand would need to focus on courting visitors from Asia and Australia as arrivals from the UK and Europe continued to dry up.
The figures come after national carrier Air New Zealand chief executive Rob Fyfe this week told MPs not enough is being done to promote the country as an attractive destination. The tourism sector has been in the doldrums since the global financial crisis in 2008, when financial markets collapsed and oil prices surged, causing widespread unemployment and eroding people's discretionary spending on long-haul travel.
New Zealanders continued to quit the country for Australia in June, with 1,029 more people leaving than arriving.
There was a net outflow of 1,029 migrants in June, smaller than 1,491 a year earlier, taking the annual outflow to 3,191, turning around an inflow of 3,867.
