HMNZS Tawhai was a New Zealand-built composite Castle-class trawler built for the Royal New Zealand Navy during World War II for the intention for use as a minesweeper, later being converted into a fishing trawler.
The vessel was ordered after the New Zealand government, facing a requirement for more minesweepers to operate in home waters, chose the Castle-class design because it was simple enough to be built with the country's limited ship construction facilities at the time. [1]
Tawhai was the last of four composite minesweepers to be built for the RNZN, the others being Hinau, Manuka, and Rimu. Tawhai was originally built for use as an LL Magnetic minesweeper, but by mid 1943, it was clear Tawhai was not needed as another LL minesweeper, so was to be completed as a conventional minesweeper. [2] At the 28 September 1943 Navy Office conference, use of the Tawhai as a servicing vessel was considered but was declined. [2] Tawhai would be 'work suspended' at the date of delivery when 95% complete and was declared surplus to the War Assets Realisation board in October 1944 for disposal. [2] In 1946, she would be purchased by the UNRRA to rebuild the decimated Chinese fishing industry. [2] [3] She was last seen with the Awatere and Pahau fishing at Formosa (now Taiwan). [2]
HMNZS Wakakura (T00) was originally a First World War Castle-class naval trawler built in Canada. Ordered by the Admiralty, the vessel, named TR 1, was loaned to the Royal Canadian Navy for use on the East Coast of Canada. She was purchased by New Zealand in 1926 and transferred to the Royal New Zealand Navy when it was established in 1941.
The Royal Naval Patrol Service (RNPS) was a branch of the Royal Navy active during both the First and Second World Wars. The RNPS operated many small auxiliary vessels such as naval trawlers for anti-submarine and minesweeping operations to protect coastal Britain and convoys.
The Castle-class minesweeper was a highly seaworthy naval trawler adapted for patrol, anti-submarine warfare and minesweeping duties and built to Admiralty specifications. Altogether 197 were built in the United Kingdom between 1916 and 1919, with others built in Canada, India and later New Zealand. Many saw service in the Second World War.
A danlayer was a type of vessel assigned to minesweeping flotillas during and immediately after World War II. They were usually small trawlers, fitted for the purpose of laying dans. A dan is a marker buoy which consists of a long pole moored to the seabed and fitted to float vertically, usually with a coded flag at the top.
HMNZS Tui (T234) was a Bird-class minesweeper of the Royal New Zealand Navy. She was commissioned in 1941 for minesweeping and anti-submarine roles. Tui was the first of two ships with this name to serve in the Royal New Zealand Navy and was named after a native bird from New Zealand.
HMNZS Moa (T233) was a Bird-class minesweeper of the Royal New Zealand Navy (RNZN) that served during World War II.
Commissioned minesweepers and danlayers of the Royal New Zealand Navy (RNZN) from its formation on 1 October 1941 to the present. The RNZN was created two years into World War II. For coherence this article covers the war years from the start, and thus includes also the New Zealand minesweepers operating from the beginning of the war.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some, known in the Royal Navy as "Admiralty trawlers", were purpose-built to naval specifications; others were adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
HMNZS Hinau was one of three composite New Zealand-built Castle-class trawlers commissioned by the Royal New Zealand Navy during World War II.
HMNZS Rimu was one of three composite New Zealand-built Castle-class trawlers commissioned by the Royal New Zealand Navy during World War II.
HMNZS Manuka was one of three composite New Zealand-built Castle-class trawlers commissioned by the Royal New Zealand Navy during World War II.
HMNZS Hautapu was one of eight steel New Zealand-built Castle-class trawlers built and commissioned by the Royal New Zealand Navy during World War II.
HMNZS Maimai was one of eight steel New Zealand-built Castle-class ships built and commissioned by the Royal New Zealand Navy during World War II.
SS Taiaroa was a New Zealand-built Castle-class ship built for the Royal New Zealand Navy during World War II with the intention for use as a minesweeper, later being converted into a fishing trawler.

HMNZS Aroha was one of eight steel New Zealand-built Castle-class ships built and commissioned by the Royal New Zealand Navy during World War II. She was the first steel Castle-class trawler launched for the Royal New Zealand Navy.
HMNZS Waiho was one of eight steel New Zealand-built Castle-class ships built and commissioned by the Royal New Zealand Navy during World War II. She was the last Castle-class trawler built for any navy.
