HMNZS Moa (T233) was a Bird-class minesweeper of the Royal New Zealand Navy (RNZN) that served during World War II.

[5][6] On 29 January 1943, in concert with her sister ship Kiwi, Moa helped to ram and wreck the Japanese submarine I-1.

However, when the Moa put the forces ashore, local natives informed them that the Japanese had left ten days before.

[9] On 7 April 1943 Moa was refuelling from the USS Erskine M. Phelps at Tulagi Harbor when Japanese aircraft attacked.

[17] Seventy-one years after her sinking, Moa's name plate was recovered by divers and is being restored for eventual display at the Torpedo Bay Navy Museum in Auckland, New Zealand.
