Air New Zealand is offering free flights to Christchurch as the battle for the cheapest airfares reaches its nadir.
The move comes just days after Jetstar offered one-cent flights every day this week - a deal which came hot on the heels of Air NZ's offer of $7 tickets between Auckland and Wellington on late night flights in the week before Christmas.
Air NZ said 1500 free one-way airfares into and out of Christchurch would be available to customers travelling between November 12 and December 2.
The airline's Australasian group general manager Bruce Parton said the seat-only free tickets would be available this week on selected flights between 16 domestic airports and Christchurch.
He said the Christchurch economy needed support and there were plenty of people from outside Canterbury who would want to fly in before Christmas to shop for presents, catch up with friends or "just enjoy some of the great food and wine the region has to offer".
