Castle Class Composite NZ Made HMNZS Manuka
HMNZS Manuka was one of three composite New Zealand-built Castle-class trawlers commissioned by the Royal New Zealand Navy during World War II.
Background[edit]
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]
Construction[edit]
Manuka was laid down on 21 October 1940 and was of a composite design, using Kauri wood due to a shortage of steel at the time. [2] Manuka was launched on 23 September 1941, being built by Mason Bros Engineering Co, located at Auckland.[3] Being the third naval ship launched in New Zealand for the Royal New Zealand Navy.
Operational history[edit]
Manuka was the third of four composite minesweepers constructed for the Royal New Zealand Navy and was commissioned on 30 March 1942. The others were Hinau, Rimu, and Tawhai. Manuka served in the LL Group (later renamed to the 194th Auxiliary Minesweeping Division)[4] which was located at Auckland.
Post-war[edit]
In 1946, Manuka was leased to the Chatham Island Fishing Company, under the condition that she would only be used in New Zealand waters, and that she would be given back to the navy in case of an emergency.[5] Manuka would follow fishing fleets, working the coast that was sheltered.[6] At the end of the day the fishing trawlers would discharge their catches onto Manuka, where they would weigh, clean and process the fish. When she was full, she would sail to Wellington, often carrying radios for repair, and mail.[6] When the vessel returned it would carry supplies for the Chatham islanders.[6] As time went by while in service, there would be more and more problems no with the boiler on Manuka. to the point where she would need a replacement.[6] Over the course of her career she would also run aground multiple times while fishing.[7] In 1950, Manuka was moored in Port Hutt, acting as a floating freezer, with local trawlers storing their catches onboard. [6] On 4 October 1952, while anchored in Port Hutt, Manuka sunk at her moorings. There was nobody aboard when she sank.
HMNZS Nora Niven – Danlayer
The Nora Niven was a 90ft steam Trawler launched 17th November 1906. Built by Cochrane & Sons of Selby for the Napier Fish Supply Co of New Zealand this state of the art trawler with an Ice Making machine that could produce 3 tons of ice in 24 hour and cool storage compartments for 80tons of fish. In June 1917, a German surface raider, the SMS Wolf entered New Zealand waters. She laid two small minefields in New Zealand waters and sank two merchant ships. One (the Port Kembla) off Farewell Spit, and another (the Wairuna) off the Kermadec Islands. Two fishing trawlers, the Nora Niven and Simplon, were fitted as minesweepers and took up sweeping duties in these areas. Another brief flurry of activity occurred when Felix von Luckner, imprisoned on Motuihe Island after being captured in the Society Islands, escaped and commandeered a small vessel before being recaptured in the Kermadec Islands.

HMNZS Wakakura (T00) was originally a First World War Castle-class naval trawler built in Canada.
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.
She displaced 530 tons standard, could manage 10 knots (19 km/h; 12 mph) and was equipped with a 4-inch (102 mm) gun during World War II.
Wakakura is a Māori word which means “precious canoe” or “training boat”
World War II[edit]
Wakakura remained in commission throughout the Second World War as a training vessel and minesweeper. For the first part of the war she was part of the 28th Minesweeper Flotilla, until the flotilla was transferred overseas. From then the Wakakura was based at Lyttleton.
“A little trawler paid a big part in the lives of New Zealand’s pre-war and wartime naval reservists. Her Majesty’s Trawler (later HMNZS) Wakakura, purchased from the Royal Navy scrap heap ‘as is, where is’ to be a training ship, also left an impression on various wharves and a couple of other ships as she roamed from port to port around New Zealand instructing young would-be sailors in naval procedures.”[1]
During 1944 the Wakakura reported that it had sighted and depth charged a Japanese submarine off the Canterbury Coast, possibly sinking it. Naval historians concluded that while it was possible for Japanese submarines to be in the area, it was unlikely at that stage of the war.[2]
The ship’s bell was installed in the Devonport Naval Base Chapel.[3]
Cargo vessel[edit]
After the war in 1947 she was sold to the Tasman Steamship Company owned by a syndicate of 17 former merchant seamen. The ship was renamed SS Wakakura and converted to a refrigerated cargo vessel for use on the trans-Tasman run from Auckland and Wellington to Sydney.[4] The ships maiden voyage as a merchant ship was in October 1947 under Captain F A Barrett from Auckland to Sydney. The newspaper stated that the voyage across the Tasman Sea was expected to take 6 days.[5]
By 1948 the company decided that the ship was to small for the Trans-Tasman run and decided to purchase a larger vessel. The ship had made seven return voyages by the time.[6] The Fiji Government owned motor ship Viti was acquired by the company as a replacement.[7] When the Viti entered service the Wakakura was used for coastal shipping.[8]
The company put the ship up for sale in November 1950, and was sold to Mason Bros. Engineering Co. Ltd, being broken up at the Viaduct Basin in Auckland.[
