Air New Zealand (ANZ) will upgrade the aircraft on some of its services between Whangarei and Auckland from a 19-seat Beechcraft 1900D to a 50-seat Bombardier Q300.
The Star Alliance carrier says that from 12 August it will replace four of its six daily 1900D services on the route with two daily Q300 services, while the remaining two services will continue to be operated using 1900Ds. The change will increase the available seats on the route by 48 each day.
The equipment change has been prompted by new Civil Aviation Authority requirements on Whangarei, which means that in some weather conditions the 1900Ds are not able to operate into the airport with a full passenger load.
"The design and configuration of the Q300 means it can operate within the current CAA restrictions with a full complement of 50 passengers," says the airline.
ANZ's 1900Ds are operated by subsidiary Eagle Airways, while the Q300s are operated by another subsidiary, Air Nelson.
