Hawaiian had increased services rapidly in response to demand on routes to Australia and the airline wanted to add breadth to markets when it could.
Dunkerley said fares would remain competitive.
"It's a competitive marketplace - where competition suggests where we have to be we'll be there."
Hawaiian was geared to leisure customers with a higher proportion of seats in economy than most other full-service carriers and that was how it managed its costs.
Dunkerley said the low-cost carrier model did not generally work on long-haul travel. "They want low prices but they don't want low service, they want the kids to be entertained and want healthy food on the aircraft - they don't want to feel they're being cheap."
The airline spent about $55 million operating the route and although load factors had started slightly below the global average of aircraft being 80 per cent full, it expected to match that figure in the coming quarter.
Flight Centre chief Mike Friend said the Hawaiian market "had gone ballistic" since the arrival of the airline and Air New Zealand had responded by putting on more capacity.
More traditional Pacific destinations such as Fiji and the Cook Islands seemed unaffected but Friend said other places including Thailand, Malaysia and Bali were more likely to suffer given they were about the same price as a package to Hawaii.
Hawaiian flies to 11 destinations on the United States mainland. Dunkerley said Los Angeles was the favourite for Kiwis, although Las Vegas had seen good take-up which the airline had not expected.
International Air Transport Association figures show Asia-Pacific is forecast to be the world's most profitable region during the next year.
"The big shifts in the world economy play well to what we're trying to do," said Dunkerley.
He said the airline pulled out of Manila in August but was starting new services to Taipei and Japan and, from next April, Beijing.
Tattoos hidden for flyers' sake
Hawaiian Airlines says it takes a similar line to Air New Zealand on frontline staff having tattoos - if they're not covered they can't work.
The airline's president and chief executive, Mark Dunkerley, said the issue came up often.
"This is a subject on which we have a great deal of debate - our policy is the same as Air New Zealand's in practice - no visible tattoos," he said.
"We look at our customer base. We carry a lot of people from Asia and they see tattoos in a much different light," Dunkerley said.
"We think it's important to make all our customers feel at home therefore our policies around this go to the most conservative."
