Jetstar is ditching services from Wellington to Queenstown as it focuses on peak-time services between Auckland and Christchurch.
The budget airline earlier this year cut Wellington-Queenstown services from daily to four times a week and will end all flying on September 1.
Jetstar said it would add five Auckland-Christchurch services, partly to capitalise on extra demand from the rebuild of the earthquake damaged city.
A spokesman for the airline said it remained committed to New Zealand in spite of today's announcement and a cutback on flying on its entire network over early winter.
Jetstar chief executive for Australia and David Hall said the new schedule would provide a better spread of services to provide more choice to the leisure and business markets on main trunk routes.
