J. F. Gmelin, 1788,
Queen Charlotte Sound, South Island, New Zealand.
May form a group with N. rudolfi, N. boobook (which see) and N. leucopsis; often considered to include N. boobook, but separated specifically by morphological and molecular differences. Formerly treated as conspecific with N. leucopsis, which differs from present species in its larger size (effect size for male wing, based on published data#R, 3.75; score 2), albeit with same-length tail (allow 1), paler brown coloration which shades paler on lower underparts so that undertail-coverts whitish where New Zealand birds rusty-buff (2), more spotting on head and neck (1), whiter spotting below (1), and feet pinkish-grey#R vs buffy-yellow to orange-buff (ns). Birds of North I formerly separated as race venatica, but differences from nominate minimal and possibly not constant. Two extant subspecies recognized.
