Kairiru Airstrip (ICAO: AYKZ) is a small general aviation facility located on Kairiru Island, an island off the northern coast of Papua New Guinea in East Sepik Province. The airstrip serves as a vital link for the island's communities, providing access to essential supplies, medical evacuation services, and passenger travel in an area with limited alternative transportation options. Kairiru Island is home to several villages and a Catholic mission, and the airstrip historically supported missionary and humanitarian operations in the region. Like many remote airstrips in Papua New Guinea, it primarily handles light aircraft operated by mission aviation organizations and small charter services rather than scheduled commercial airline routes.
