Air New Zealand will start night flights into Queenstown in July.
The airline has been working for several years on plans to extend its services to and from the resort town.
Queenstown Airport is spending up to $18 million widening its runway to 45 metres, and installing navigation lights.
Air NZ says the night flights will offer more options and flexibility for travellers as well as better connectivity to Auckland's international hub.
The new schedule "will be a game-changer for international travellers in particular, with same-day connections as well as reduced connection times both to and from a range of destinations across Australia, Asia and North America", said chief sales and commercial officer Cam Wallace said.
