Air New Zealand (ANZ) will end two domestic services in the coming months.
The carrier says it will suspend five times weekly Wanganui-Wellington service in December, and withdraw its Auckland-Masterton service from February 2014.
ANZ will also raise the total seat capacity of the Auckland-Rotorua route by 30%, where it will deploy a 50-seat Bombardier Q300 aircraft to replace the 19-seat Beech 1900D. This will take place in February 2014.
The recent introduction of ATR72-600 turboprops into ANZ's domestic fleet has enabled it to free up capacity of the Q300s for the Auckland-Rotorua route. By replacing the Beech 1900Ds with Q300s, the route's economic viability has increased, the airline adds.
Rotorua is located in the Bay of Plenty region, on New Zealand's North Island.
