ZK-XXX (aircraft registration format)

ZK-XXX is a common aircraft registration prefix used in New Zealand, where "ZK" is the country code assigned by the International Civil Aviation Organization (ICAO). The format consists of "ZK" followed by a combination of three letters or sometimes numbers, uniquely identifying each aircraft registered in New Zealand. This registration acts as an aircraft's official ID, similar to a license plate on a car, allowing authorities and the public to identify and track the aircraft. It ensures safety, regulation enforcement, and proper record-keeping within the country's aviation system.
