The Christchurch earthquakes and the flight schedule havoc caused by the Chilean volcano had not damaged tourism as much as feared, he said.
"These adverse events had their main impact during what is always the low tourism season. On an annual basis the arrivals have held up and spending hasn't collapsed."
Tourism Industry Association policy and research manager Simon Wallace said a positive to take from the latest data was the continual growth of China.
Chinese visitor numbers were up 25.2 per cent for the year ended June at 132,000, with spending up 12.4 per cent at $410 million.
The level of international tourist spending could be increased within the changing mix of visitor markets, Wallace said. "It's about the service, it's about the types of products that we're offering and getting that added value into the products and that will encourage more spend and I think many of our operators are starting to acknowledge that."
The falls in global markets during the past few days would impact confidence in some markets, like the UK and US, which would spill through to tourism. "I think clearly that's the case but with the exchange rate dropping as it has done over the last few days it's actually a good thing because it means that international visitors are getting more for the their dollars here," Wallace said.
Goldman Sachs economist Philip Borkin said UK and US households were paying down debt and overseas travel - particularly to a far away country like New Zealand - was a luxury item for many people.
"When you throw the currency on top of that which makes it quite an expensive destination to even start with it's hardly one where you're going to see strong pick up going forward.
"It's hardly a favourable outcome for the New Zealand tourism sector unless the currency continues to fall, and while that's possible in the near term, we still believe that given the US problems the US dollar will eventually weaken again once we get this little rout out of the way and up goes the kiwi."
