Air New Zealand is pulling flights between Auckland and Kapiti Coast from April.
The domestic service has operated since 2011 and the national carrier says passengers booked on flights are April will be "re-accommodated on alternative services".
"Customer demand for domestic travel continues to experience steady growth with the airline adding 630,000 more seats nationwide this financial year alone and an expectation that it will further grow the regional turboprop network alone by 4.5 percent or 265,000 seats in the coming financial year, " Air New Zealand said this morning.
"Against this backdrop, the airline is making domestic schedule adjustments to better match its aircraft seat capacity to areas of growing customer demand and is committed to continuing to grow the wider regional network.
"On withdrawal, Air New Zealand will extend support to any other airline that operates the route as it has in other ports," the airline said.
Air NZ will fly its last Auckland-Kapiti service will run on April 3.
Kapiti Coast Mayor K Gurunathan said it was "appalling" that the national carrier would treat a community in this manner.
He said he was given 24-hours notice that Air New Zealand was pulling the service.
