Sometimes placed in genus Nettion. Commonly treated as conspecific with A. aucklandica and A. nesiotis, and relationship clearly very close, but sometimes separated out#R#R and differs from both in its more obvious speculum in male (2); different patterning on upperparts in male (clear pale borders of feathers vs none, much less close barring, no green reflections in dorsal feathering) (3); generally more white at base of foreneck (1); larger size (wing female 194±8 vs 120±0; effect size 9.25; score 3)#R. Population of South I has sometimes been assigned a separate subspecies, peculiaris. Hybridization with A. platyrhynchos recorded. Monotypic.

Distribution:

Great Barrier I and isolated areas of North I (Mimiwhangata Bay and Teal Bay) and SW South I (Fiordland), in New Zealand; formerly more widespread (including Chatham Is). Reintroduced at several locations (Coromandel, Tawharanui, Cape Kidnappers, Tuhua I), but uncertain as yet if these populations will survive.
