The colonial service Defender-class torpedo boats were designed by Thornycroft & Company for the defence of New Zealand, built at Chiswick in 1883 and shipped to New Zealand. They were quickly obsolete and were left to deteriorate in situ. The remains of Defender are preserved at the Lyttelton Torpedo Boat Museum.
