Jetstar has launched a New Zealand sale, Newshub reports, with 50,000 domestic airfares between the main centres on sale from $26 each. Flights between Auckland, Wellington and Christchurch are $26 each way in the sale, while flights to Queenstown cost $55 from Auckland or $35 from Wellington. For domestic travellers, the sale is a good sign that competition between Jetstar and Air New Zealand is heating up.
