Sometimes placed in genus Nettion. Commonly treated as conspecific with A. chlorotis (which see for specific differentiation) and A. aucklandica, and relationship clearly very close, but sometimes separated out#R#R and differs from aucklandica in its shorter wings (male mean 132 vs 141#R, but correlated with weight difference below; ns); longer tail (male mean 89 vs 77#R) (at least 1); much lighter weight (mean for breeding males 371 vs 551#R) (score 3); upperpart pattern with clear pale borders to feathers (1); more white on lower flanks (1); darker plumage overall (1). Tail and weight proportions are confirmed elsewhere#R. Monotypic.
