Air New Zealand is ramping up its regional services in the wake of Jetstar's withdrawal.
The airline will operate an additional 253 one-way flights in December on services it operates between Auckland and Napier, New Plymouth, Nelson and Palmerston North, as well as between Nelson and Wellington, adding more than 15,500 seats in the process.
Cam Wallace, Air New Zealand chief revenue officer, said the airline has been looking at ways to help support the routes affected by Jetstar's withdrawal from the regions.
"Air services are extremely important for regional New Zealand, particularly over the busy holiday period, so we're pleased to be able to step in and add capacity to the routes impacted."
Wallace said the airline was also looking at additional capacity on regional services post December.
