HMNZS Mako was the first of 16 Harbour Defence Motor Launches ( HDML) to be delivered to the RNZN in 1942 and served in that function during WW2. In 1948 she was reclassified as a Seaward Defence Motor Launch (SDML) and then served as a coastal Fishery Protection vessel for the next 28 years. The engines were replaced 1958 with Foden 12 220 bhp increasing her speed to 12 knots. Over the years Mako was also used for many other tasks, including assisting in a whale survey in 1962. This excellent seaboat remained a familiar sight around the NZ coastline until 1976 when she was decommissioned and sold. Mako is now in private use in Australia.
