Brief History
Short Mk V Sunderland NZ4115

MOTAT’s Sunderland is one of the rarest aircraft in the collection. It is one of four remaining in the world and the only example in New Zealand.

This Sunderland was one of sixteen that were brought to New Zealand after World War II for the Royal New Zealand Air Force. Most of its service was with 5 Squadron at Laucala Bay in Fiji, but it also served with the Maritime Conversion Unit at Hobsonville.

The Sunderlands were much loved and appreciated in the Pacific for the search and rescue and mercy missions they carried out. This included anything from searching for missing fishermen, survivors from aircraft wrecks or missing vessels. They also dropped off emergency medical equipment and picked up sick or injured people and took them to hospital.

The Sunderlands were replaced by Orions in 1966 when NZ4115 was withdrawn from service and donated to MOTAT. It was ferried to its present site at MOTAT and reassembled by the RNZAF during February/March 1967.
