HMS Taiaroa was a colonial service Defender-class torpedo boat designed by Thornycroft & Company for the defence of New Zealand. She was named after Te Matenga Taiaroa, a 19th-century Māori chief of the Ngāi Tahu iwi. She was built at Chiswick in 1883 and shipped to New Zealand, where she was assigned to the defence of Port Chalmers.
