A number of subspecies are recognised; Placostylus bollonsi arbutus and P. b. bollonsi are classified by the New Zealand Department of Conservation as being Nationally Endangered, while Placostylus bollonsi caperatus is classified as Nationally Critical.[2]

Buckley et al. (2011)[3] found based on molecular phylogeny research and shell morphology research, that there are no subspecies of Placostylus bollonsi.[3]
