This species is classified as Vulnerable because it has a very small population. The possibility of accidental introductions of invasive mammal species to the islands is a continuing concern, although the species occurs at enough locations to be relatively secure in the short term.
Anas aucklandica (Sibley and Monroe 1990, 1993) has been split into A. aucklandica, A. chlorotis and A. nesiotis following Daugherty et al. (1999).
