Launched in 1911 to carry the Royal Mail and served on the San Francisco and Sydney runs. She was employed as a troopship during World War I and World War II. After finishing her troop service in June 1919 she was refurbished and converted from coal to oil burning at Port Chalmers. She returned to her previous route from 26 June 1922. She was sold to Cia Naviera del Atlantica, Piraeus in 1948 and renamed Cyrenia. She was sold in 1949 to Hellenic Mediterranean Lines and undertook service from Genoa and Piraeus to Fremantle, Melbourne and Sydney, carrying Greek, Italian and Jewish refugees and migrants.
In Greece the S/S Cyrenia is prominent due to Nikos Kavvadias' poem "The Seven Dwarves on the S/S Cyrenia and Thanos Mikroutsikos' song mentioning the ship. Kavvadias was the ship's radio operator.
