Type locality of Bathylagichthys kobylianskyi, Hikurangi Trench. Known from the Norfolk Ridge and Tasman Sea, and most specimens were collected in the vicinity of East Cape, North Island. The southernmost capture was on northern Chatham Rise slope (NMNZ P.35456) and the northernmost on the Norfolk Ridge, just outside the New Zealand EEZ. Another lot of specimens was collected in the northern central Tasman Basin, well outside the New Zealand EEZ. Individuals of this species were usually trawled at relatively shallow depths of 15 - 320 m over a bottom depth range of 800 - 4700 m (Ref. 97709).
