Air Chathams claims "skyrocketing" prices being charged by Aotearoa's largest Airport will dampen demand on regional routes and threaten its viability.
Auckland Airport plans to spend up to 8 billion dollars over 10 years upgrading facilities and that means airlines are facing increased user charges to cover costs.
The airport says its domestic charges have been rock bottom for years and up to 50 % lower than comparable airports.
Air Chathams operates services to Whakatane, Whanganui, Kapiti and the Chatham & Norfolk islands from its hanger in Auckland.
Chief operator officer Duane Emeny speaks to Lisa Owen.
