Air New Zealand's last flight of the day between Auckland and Wellington is being promoted with a $29 "Night Rider" fare.
The airline says in a release that it adds the "equivalent" of 100,000 low-cost seats a year between the two cities, with $29 for a seat-only ticket and an extra $10 for a bag.
Between Sunday and Friday, flights will leave both cities at 10pm.
On Saturdays, the Auckland flight will leave at 9pm and return from Wellington at 10.30pm.
The 133-seat, Boeing 737 flights are on offer from today and kick in from November 5.
