However, the Board of Airline Representatives says charges are still a threat to travellers.
Legal counsel for BARNZ Kristina Cooper said while Auckland's charges for landing aircraft on the airfield and for passengers passing through the domestic terminal were reasonable, the prices for passengers passing through the international terminal were "excessive and generate an excessive profit.
"Airlines operating in a hugely competitive environment are forced to either pass those costs on, so those fees ultimately come out of travellers' pockets, or else absorb the costs which can result in reduced services," she said.
BARNZ says New Zealand has one of the lightest handed regimes for airport pricing among developed countries.
"It is time for New Zealand to match good international practice and introduce some curbs on airports'
Wellington Airport - which the commission found could make a profit of $38 million to $69 million more than was needed for a "reasonable return" over the five years to 2017 - is going back to consult with airlines before setting its final fees.
