Opening night has sold out, but tickets are still available for other World of WearableArt shows ahead of the fashion festival's return to the capital next Thursday.
WOW chief executive Meg Matthews said ticket sales opened with "a complete boom" on February 1.
"We are going into the show 99 per cent sold out, which is a really strong position to be in.
"Opening night is sold out, but there will still be some tickets left available for the rest of the shows."
WOW began in 1987 as a promotion for a rural art gallery in Nelson, and is now an internationally recognised show.
Of the 158 garments on stage this year, 51 per cent were from domestic designers, and 49 per cent were from international designers, Ms Matthews said.
"That firmly cements us as an international competition.
"It is a largely New Zealand audience, but this year is our biggest-ever contingent of international designers coming to the show, and they will, of course, bring family and friends with them."
A total of 47,000 tickets were available for WOW's 11 shows, beginning on September 26 and finishing on October 6.
Hospitality New Zealand deputy chief executive Sara Tucker said bookings related to WOW were very strong across the board, and on par with last year.
Visitors seemed to be coming mainly from locations around New Zealand, although Boulcott Suites in the inner city had groups booked in from Australia and Singapore, she said.
WOW attracted "large numbers of groups of women who are big food and beverage spenders and shoppers," Ms Tucker said. "It's been a bit quiet recently, so this is very welcome."
Intercontinental Hotel director of sales and marketing Geoff Naumann said bookings were about the same as at this time last year.
"The WOW side of things is peaking on Friday, Saturday and Sunday for those out-of-towners coming for performances.
"We will still fill up during the WOW period."
