The private plan change proposes to amend the existing air noise boundaries and associated district plan provisions to allow for projected airport growth until 2037.
It was adopted in part by the council, but was appealed by Air New Zealand, Remarkables Park Ltd, Shotover Park and Wakatipu Residents Against Air Noise Inc. The last-named withdrew during the February hearing of the matter.
Remarkables Park and Shotover Park, the Queenstown Airport Corporation, the council and Air New Zealand reached an agreement over changes made to the plan change during the February hearing.
At the Frankton Community Association annual meeting at the airport on Wednesday night, airport chief executive Scott Paterson said although an agreement was reached, the court was still to make a decision.
"Our expectation is they will ratify it.
"There may be some changes.
"We'll be disappointed ... if the Environment Court is seen to overturn large parts of what the parties agreed ... Until we see it in writing, we won't know."
Should the agreement be confirmed by the court, it would place new air noise boundaries around the airport and the community.
"That places on us an obligation to comply.
"It places on notice any developers looking to build within those boundaries the standard they need to build [to] and it also places on us ...an obligation around mitigation."
Included in the airport's proposed mitigation measures was retrofitting some houses in the Frankton area with acoustic insulation and mechanical ventilation, meaning fresh air could circulate in homes without windows being open.
Other home owners would receive a "contribution towards ventilation".
"Who gets what?
"We don't know.
"All we know at the moment is some big lines on a map.
"Our desire is to turn those lines ... into conversations; identify people and addresses.
"All I can tell you right now, the focus from the airport is very much around trying to understand who lives where."
Mr Paterson said, should plan change 35 be accepted by the Environment Court, a community liaison group was likely to be established to help determine how the process would progress.
