HMNZS Hinau, first NZ Built Castle-class trawler and first RNZN ship to be built in New Zealand.

 

Hinau was laid down in 1940 and was of a composite design, using Kauri wood due to a shortage of steel at the time.^[2] Hinau was launched on 28 August 1941 at Senior Foundry Ltd, located at Auckland.^[3] Being the first naval ship built in New Zealand for the Royal New Zealand Navy.

In 1954, Hinau along with Rimu, and the tug Toia were sold to F. Appleton of Penrose to be scrapped at the Viaduct Basin.^[9][11] In 1958, the hulk of Hinau would be towed and ran aground for use as a breakwater and shingle bin in Whakatīwai, where she remains today.^[9] In 1998, she featured on the cover of the Dave Dobbyn album, The Islander.
