Mr Dalton said he did not believe the price gouging claims.
"If in fact they were charging horrendous prices and it was so enormously profitable for Air New Zealand that they were able to subsidise other services elsewhere, then it would take five minutes and there would be a competitor in here," he said.
Mr Dalton and Hastings Mayor Lawrence Yule are due to meet Air NZ's regional services manager, Ian Collier, next week to voice concerns about the company's plans to restructure its Hawke's Bay operations.
The plan includes a proposal to close subsidiary Air Nelson's Napier crew base which would see 36 jobs, and about $2 million in annual wages, shifted out of the region.
The airline would reduce Q300 flights to the Bay, replacing them with larger ATR72 aircraft, saying the move will boost capacity in and out of the region, maintaining downward pressure on fares.
While Mr Dalton and Mr Yule have said they are determined to press the case for the region to retain jobs and services, Mr Dalton said he accepted the airline's plans to increase capacity on Hawke's Bay routes was aimed at keeping fares down.
"We can't have it every which way and I think we need to be very careful with Air New Zealand," he said.
"Don't forget a town like Masterton jumped up and down and made such a big hoo-ha about them being gouged on fares out of the provinces that Air New Zealand said: that's all right, we'll stop servicing Masterton."
Air NZ spokeswoman Emma Field said the Masterton decision had nothing to do with complaints about price gouging.
"Air New Zealand makes business decisions based on business realities. Decisions on where to operate to and how much seat capacity to put into any given market are driven by economic factors," she said.
