The New Zealand dollar is down from a high of 88c against the greenback last July to just over 70c today, falling more than a cent following the Reserve Bank's decision to cut interest rates.
Travel agents say the falling dollar doesn't necessarily stop people taking trips overseas but may mean they spend a shorter time there, choose cheaper accommodation or eat out at least expensive restaurants.
However, the lower kiwi makes this country more attractive to tourists.
Tourism Industry Association chief executive Chris Roberts said a sustained fall in the dollar was great news for the sector and provide a second wind after strong growth in the past 18 months.
The fall against the Australian dollar was welcome, especially just before the ski season.
"It does take some pressure off - being around 90c is a lot better than close to parity," he said.
Tourism New Zealand, the government funded marketing organisation, is about to launch a campaign in key markets overseas and with New Zealand less expensive now the timing was ideal.
Roberts said although it was hard to measure, the domestic tourism industry did benefit when New Zealanders were discouraged from travelling overseas.
