Probably closest to P. crassirostris, and sometimes still considered conspecific. Sometimes subdivided into two races, with nominate restricted to populations breeding close to Australia and New Zealand (and sometimes applied to Falkland Is), and race eatoni for all others#R, but uncertainty as to which race would be present at some locations; in past, name eatoni was erroneously applied to some populations of P. crassirostris#R. Several other races have been proposed, most notably subantarctica (Antipodes Is). Monotypic.
Subtropical and subantarctic waters, breeding in Falkland Is and South Georgia E through S Indian Ocean to St Paul and Kerguelen Is, and islands off SE Australia and Tasmania (including Bass Strait) and off New Zealand (S from Poor Knights, and including Snares Is and Chatham Is), S to Macquarie, Campbell and Antipodes Is.
