Pittosporum cornifolium, known as tāwhiri karo in Māori, is a species of plant in the Pittosporaceae family. It is an epiphytic plant endemic to the North Island and the Marlborough Sounds of the South Island, New Zealand. In the wild it is considered rare and threatened, although it occurs more frequently on offshore islands in the north-east, along with P. kirkii, the only other epiphytic member of the genus. Also grows well as a ground plant and is a popular garden ornamental with two recognised cultivars.
