Hemiphaga is the genus containing two species of large pigeons from New Zealand.
There are two subspecies of New Zealand pigeon, Hemiphaga novaseelandiae: H. n. novaseelandiae of mainland New Zealand and the Norfolk pigeon (H. n. spadicea) of Norfolk Island, now extinct. The subspecies differed in their plumage colour and shape.[1]

The genus contains two species:[7]
