During the Second World War the New Zealand Government purchased three Bird class minesweepers and four Isle Class minesweepers.
To this small fleet, eleven minesweeping trawlers were built in New Zealand along with twelve anti-submarine, B Type Fairmiles. Sixteen Harbour Defence Motor Launches (HDMLs) were also purchased from overseas.
After the war, many of these 72 foot HDMLs were retained to work around the New Zealand coast.
This is their story as told by those who served in them.
