Abstract Frostfish spawning, as indicated by the presence of planktonic eggs, was observed mainly in north-eastern, but also in south-western, New Zealand waters in spring to autumn. Spawning takes place in the afternoon in outer shelf waters 50-200 m deep, with surface temperatures and salinities between 17.5 and 22.0°C and 35.3 and 35.6%o respectively. Egg and oil droplet diameters ranged from 1.65 to 1.75 mm and 0.40 to 0.43 mm respectively.

Keywords Trichiuridae; Lepidopus caudatus; spawning; eggs; larvae; distribution.
