Corporation chief executive Steve Sanderson yesterday said the new noise boundaries, which had been extended in all directions, would allow for the airport's projected growth through to 2037.
If the change is approved, the airport's operating hours, which begin at 6am, will also be extended by two hours to midnight.
In the past 13 months, the corporation has held a public open day, attracting about 80 people; met residential groups; completed mail drops to more than 2000 residents; and held individual discussions with several residents.
It had also spoken extensively to its "neighbours", including Five Mile, Remarkables Park Ltd, Quail Rise and Stalkers.
"We are confident this noise plan change will go through, although along the way it may . . . change," Mr Sanderson said.
Queenstown relied on the airport for tourist arrivals and the facility was indirectly responsible for more than $500 million of its gross contribution to the district and more than 1000 full-time jobs.
The corporation was also committed to meeting the costs of acoustic insulation in living and sleeping areas of homes within two of its revised boundaries, he said.
Between 70 and 80 houses were expected to fall into the night-time noise boundary and the air noise boundary; the two closest boundaries to the airport.
The cost of insulation for the mix of houses was difficult to estimate. Each house would be assessed individually if the proposal was approved.
The application will be publicly notified in coming weeks before it goes to a resource consent hearing.
The airport has already exceeded the allowed growth in its existing noise boundary, which took into account growth to 2015.
Possibly the most contentious of the noise boundaries was the night-time noise boundary, Mr Sanderson said.
It would become an issue when the runway-end safety area was constructed and approved (the deadline for which is October 2011), the Civil Aviation Authority had satisfied its safety requirements, and runway lights were installed.
He said the proposal to extend the airport's hours to midnight was linked to the night-time noise boundary.
The extension, if approved, would allow for night flying.
Frankton resident Robert Rutherford said he would not object to the corporation's plans as "we made the decision to live here".
"I don't think anyone else plans to object either."
