"Tourism businesses are reaping the financial rewards and New Zealand society has benefited with more jobs, more economic activity and the vibrancy visitors bring as they travel around our country."
The number of international arrivals had risen by more than 15 per cent to 3.2 million in the past year, helped by airline capacity ramping up. The spike in tourism, particularly for summer months, has led government marketing body Tourism New Zealand to shift its focus to promote the shoulder seasons.
"Outside of the short peak periods we have lots of spare capacity. We still need to have more success in growing the shoulder," said Roberts.
Tourists were still concentrated on the main tourism "hotspots."
"There's been no evidence of dispersal in the past two years."
Roberts said while there had been some concern about too many tourists coming to the country, the figures did not back this up.
"Even in the peak season it is relatively low by international standards. On any one day in the peak season there are six visitors for every 100 residents."
