Roy Morgan's international director of tourism, travel and leisure, Jane Ianniello, said that with the strong Australian dollar and cheaper airfares the United States had become a more appealing and affordable destination for Australians.
"By contrast, the widespread media coverage of the Christchurch earthquake in late February 2011, followed by the June 2011 quake, has caused the 'Shaky Isles' of New Zealand to lose favour as a holiday destination. The popularity of both islands has been adversely affected," she said.
Statistics New Zealand figures show the number of tourists from Australia dipped a fraction last year to 1,155,792, down 634 from 2011.
The 2011 figure was boosted by Rugby World Cup visitors and Tourism New Zealand chief executive Kevin Bowler said numbers were up 3 per cent on the year before the tournament.
"We still see opportunities in that market particularly in special interest around ski-ing, the new cycle ways, there's a whole lot of new things that Australians haven't found out about New Zealand," he said.
The figures for last year show a 6 per cent rise to 476,000 in the number of arrivals from Australia visiting friends and relatives, not traditionally the highest spenders.
"We'd like to see the holiday segment of the market growing more than it is. Obviously holiday makers are going to spend more consuming products and services," said Bowler.
