|}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.
Background
The vessel was ordered after the New Zealand government, facing a requirement for more minesweepers to operate in home waters, chose the {{sclass2|Castle|trawler|0}} design because it was simple enough to be built with the country's limited ship construction facilities at the time.{{Cite web |date=2015-10-06 |title=HMNZS Waiho Castle-Class Minesweeper |url=http://forum.rnzna.org.nz/index.php?action=dlattach;topic=110.0;attach=39 |archive-url=https://web.archive.org/web/20091221205319/http://forum.rnzna.org.nz/index.php?action=dlattach;topic=110.0;attach=39 |archive-date=2009-12-21 |access-date=2023-11-07 |website=National Museum of the Royal New Zealand Navy |language=en-GB}}
Operational history
File:HMNZS Tawhai's launch.jpg. ]]
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.{{Cite book |last=McDougall |first=R.J. |title=New Zealand Naval vessels |publisher=GP Books, Informing New Zealanders |year=1989 |isbn=0-477-01399-6}} At the 28 September 1943 Navy Office conference, use of the Tawhai as a servicing vessel was considered but was declined. 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. In 1946, she would be purchased by the UNRRA to rebuild the decimated Chinese fishing industry. {{Cite web |date=10 September 1946 |title=Trawlers for China |url=https://paperspast.natlib.govt.nz/newspapers/GISH19460910.2.41?end_date=31-12-1989&items_per_page=10&page=8&phrase=2&query=+tawhai+&snippet=true&sort_by=byDA&start_date=01-01-1945 |access-date=2023-12-10 |website=paperspast.natlib.govt.nz}} She was last seen with the Awatere and Pahau fishing at Formosa (now Taiwan).
