New Zealand falcon exists in the park in small numbers, and the great spotted kiwi is present on both sides of the divide. Riverbeds provide habitat for a variety of species. Pipits, paradise shelducks and Australasian harriers live there throughout the year. In addition, the riverbeds attract migrant birds such as South Island oystercatchers, black-fronted terns, banded dotterels and Canada geese. Birds of the streams and lakes include grey ducks, black teals and black shags.
Blue ducks exist in small numbers in the remoter mountain streams.
