HMAS Lachlan paid off at Fremantle, having steamed 32,737.7 miles since commissioning in the Royal Australian Navy. She commissioned the same day as HMNZS Lachlan under the command of Lieutenant Commander PD Hall DSC RN. Lachlan arrived in Auckland in November 1949. The period of the loan was initially three years but this was extended several times and in 1962 Lachlan was purchased by the New Zealand Government. The ship’s service as a unit of the Royal New Zealand Navy was again as a survey vessel. In February 1975 she paid off for alongside service and later in the year she was deleted from the Navy List.
