Formerly treated as a race of N. boobook (which see) or, on molecular basis, of N. novaeseelandiae, but recently treated as a separate species#R#R, on basis of “DNA evidence…allopatric distribution…and some external similarity to its Australian counterpart”. In fact, is notably different from Australian boobook by virtue of smaller size (allow 2), much darker, richer brown coloration (2), more extensive spotting above, much more spotting vs streaking below (2) and different voice (allow 3); differs from similarly (but perhaps not identically) voiced N. novaeseelandiae 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). Monotypic.
