It was originally described by R. Kner and F. Steindachner in 1867. It is a non-migratory tropical blenny known from coral reefs in the western Pacific Ocean, and has been described from the Ryukyu Islands to eastern Australia. It has been recorded swimming at a depth range of 0–30 metres.

This species is endemic to New Zealand where it occurs around the North and South Islands, Stewart Island, Auckland Islands, Snares Islands, Antipodes Islands and Chatham Islands. The adults occur along sheltered coastal reefs and in harbours and bays with substrates consisting of rock and shell. They range in depth from intertidal pools to 12 metres (39 ft), or more. They prey on small benthic animals which are swallowed whole.
