The HS Maunganui was a hospital ship that served in the Royal New Zealand Navy (RNZN) during World War II.

Maunganui was converted from a 30-year-old oil burner, and was larger than the previous ships operated by the RNZN, those being the Maheno and Marama.

She set sail for Suez a day after finishing conversions, leaving on 22 April 1941 to assist 2 NZEF.

She arrived at Suez on 22 May 1941 taking casualties from Greece and Crete before returning to New Zealand on 10 June 1941 full with patients.

[1] On her 15th voyage, the ship was diverted to the Pacific to assist around various islands making repeated voyages to pick up and treat patients until the end of the war when she brought back one final load of 2 NZEF casualties from Italy and Egypt.
