Air Chathams Limited is an airline based in Te One, the Chatham Islands, New Zealand. It was established in 1984 and operates scheduled passenger services between the Chatham Islands and the North and South islands of New Zealand, as well as local charters. Its main base is Chatham Islands / Tuuta Airport. A fully owned subsidiary (Chathams Pacific) operated scheduled flights in Tonga until March 2013. The introduction of Chinese (PRC) aid financed aircraft and training facilities at the request of the Tongan government introduced competition to Chathams Pacific's routes. Air Chathams Ltd management decided not to compete with the new airline, Real Tonga, and ceased all Tongan operations. Air Chathams began serving the Auckland to Whakatane route on 29 April 2015.
The Britten-Norman Islander and Beechcraft Queen Air aircraft were used exclusively by the Air Chathams subsidiary, Chathams Pacific, in Tonga. The Convair 580s and the Metro III are used across the company's operations as well as contract freight services and charter work. The Cessna 206 provides a non-regular service between Chatham Island and Pitt Island and is on standby for Search And Rescue or local flights around the Chatham Islands as well.
