Air Chathams Limited is an airline based in Te One, the Chatham Islands, New Zealand. It was established in 1986 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 aid financed aircraft and training facilities made the continuation of Chathams Pacific impossible.
