"This is great news for tourism and those wanting to hit the slopes," says Carr.
"When it comes to our Auckland-Queenstown route, we'll be offering even more capacity over the school holidays than we did during the same time last year through upgauging 140 return services from our A320 to our larger A321neo aircraft between 29 June and 26 July."
The upgauging of aircraft will also add extra capacity to routes from Blenheim, Dunedin, Gisborne, Hamilton, Invercargill, Kerikeri, Napier, New Plymouth, Nelson, Palmerston North, Rotorua and Tauranga.
The airline told the Herald the 787-9 fleet was previously deployed between mid-to-long haul routes such as Chicago, Shanghai and Taipei prior to the Covid pandemic, due to their fuel efficiency.
Flights between Auckland and Christchurch are on sale for between $278 - $308 return.
