The "faster, larger and more comfortable" Air Chathams SAAB 340 is set to service Whakatāne, with the first flights beginning on November 29.
With demand continuing to grow for air travel to and from the region, the SAAB can cater for up to 34 passengers, almost doubling the existing Metroliner service at 19 seats.
Air Chathams said in a statement the SAAB was faster, larger and more comfortable than the Metroliner and would be used for peak-demand services initially.
Passengers on Friday afternoon flights from Auckland at 3.15pm and 6.35pm, as well as those travelling from Whakatāne at 4.45pm, will fly in the larger SAAB 340.
