Waingongoro, North Island, New Zealand.
Occasionally placed in genus Notornis. Previously considered conspecific with extant P. hochstetteri of South I; recent studies suggest that the two are sufficiently distinct in biometrics and genetics to be treated as separate species, having evolved independently#R#R. [Note that, in earlier BirdLife International publication#R, name P. mantelli was incorrectly assigned to the extant form, while name P. hochstetteri was incorrectly assigned to the extinct form.] Monotypic.
Estimated year of extinction 1894. Demise attributed to anthropogenic modifications of habitat combined with hunting and predation.
