Queenstown mayor Vanessa van Uden says the community will be consulted about the effects of night flights at the region's airport.
At present, flights must leave no later than 30 minutes before official twilight because special lighting and the terrain prohibit night operations.
The Airport Corporation is pushing forward its case for evening operations, allowing aircraft to land and depart at the airfield after dark.
The airport is challenging for pilots because of the terrain.
The Civil Aviation Authority is due to release a safety report in the next few weeks.
Ms van Uden says if the safety case is made that night flights are possible then the community will be consulted about the implications.
