Growth was coming from leisure travel rather than corporate business and was being driven by high consumer confidence, the high New Zealand dollar, cheaper air fares and new products sold through New Zealand stores.
The company's managing director, Graham Turner, said Australia, Britain, Singapore and China delivered record first-half earnings and New Zealand and South Africa recorded "strong" year-on-year growth.
India and Dubai both performed solidly but the United States and Canada finished the half "below expectations".
Meanwhile, online travel group Australian-based Wotif.com has posted an 18 per cent slide in its half-year profit. Wotif said it had made a net profit of A$22.6 million for the six months to December 31, down from A$27.5 million a year ago.
The company attributed most of the losses to increased spending on marketing and information technology.
