On 1 February 1884 Defender and Taiaroa were shipped aboard the sailing ship Lyttelton from London to Port Chalmers, New Zealand. Taiaroa was sent to Deborah Bay, at Port Chalmers (port of the city of Dunedin), where a boat house was established for her.[1]
She received a pair of 18-inch Whitehead torpedoes that had been fitted at build to her two sisters, Waitemata and Poneke. These had to be dropped together to avoid unbalancing the boat's narrow hull. All four boats of the class quickly became obsolete, and before 1900 had fallen out of use.
After falling into disuse, she is believed to have been broken up. The mole built for the use of Taiaroa is now used as a pull-off carpark on the harbour road.
