The Kermadec Spiny Dogfish is known from the Kermadec Islands (north of New Zealand) in the Southwest Pacific, specifically around Raoul Island, and south to at least Curtis and Chesseman Islands. However, this species is potentially widespread on oceanic ridges and seamounts in the Southwest Pacific.
This species is sympatric with the larger Northern Spiny Dogfish at Raoul Island. Bottom longline and dropline catch-effort data and submersible footage indicates that Squalus spp. (probably Northern Spiny Dogfish and Kermadec Spiny Dogfish) are abundant at upper slope depths around the Kermadec Islands (Beaumont et al. 2009).
