Conducted by the Tourism Industry Association (TIA) the survey also found that 12 per cent of exhibitors estimate that they expect to generate more than $100,000 in turnover as a result of attending the event.
Tourism New Zealand's Chief Executive Kevin Bowler says TRENZ is a key event on the travel trade's annual calendar.
"TRENZ is much more than a just a trade show. By bringing key international travel sellers down to New Zealand, they are able to experience first-hand the very product they promote.
"As a result, their increased knowledge and personal experience will make them more effective at selling New Zealand - resulting in more visitors, staying longer and doing more."
As a result of attending TRENZ Buyers say they expect to increase total client numbers by almost 10,500, 4.5 per cent increase on the previous year's total. They commonly identified 4-5 new products or suppliers of interest.
"Delegates have told us this was one of the best TRENZ events ever, with 99 per cent of international Buyers and 98 per cent of New Zealand Exhibitors rating their attendance as either 'very successful' or 'successful'," said Tourism Industry Association Chief Executive, Martin Snedden.
These delegates also reinforced the importance of TRENZ, with 80 per cent of Buyers and 72 per cent of Exhibitors saying TRENZ is more important than other purchasing and marketing activities they undertake.
"This is an excellent result for TRENZ and TIA. It's fantastic to see that delegates continue to rate TRENZ as one of the most important marketing activities they undertake. Even in this era of virtual meetings, you can't beat face-to-face contact and solid relationships to seal a deal," Mr Snedden says.
Planning is now underway for TRENZ 2013, which will be in Auckland, 21-24 April 2013.
TIA manages TRENZ, which brings together about 280 New Zealand tourism operators (Exhibitors) with a similar number of invited international travel and tourism Buyers and Media from New Zealand's major tourism markets. The event directly helps to grow New Zealand's tourism industry, worth $9.7 billion in foreign exchange annually.
TRENZ is supported by Tourism New Zealand, Air New Zealand, Qantas and other industry partners.
