Hāwea Conservation Park is home to many threatened birds, including kea, rock wren, falcon, black fronted tern, wrybill, kaka and parakeets, as well as gecko, and special plant species including thePittosporum patulum, the red flowering mistletoe, the tree daisy Olearia lineata and coral broom.
The park also has spectacular landforms including the broken, craggy tops of the McKerrow Range and the high, glaciated peaks of Barth, Huxley, Strauchon and Brewster. The park straddles the transitional zone from the glaciers of Mount Aspiring National Park to the dry grassland of the Lindis country.
