Stewart Island/Rakiura is the third-largest island in New Zealand, diminutive in comparison to the country’s North Island and South Island. Yet it hosts a population of one of the largest of the kiwi: the Stewart Island tokoeka. This flightless bird, a subspecies of the Southern brown kiwi (Apteryx australis), numbers in the thousands on the island, dwarfing its human population of approximately 500.
The avian national icon is just one slice of the natural riches on Stewart Island/Rakiura, a roughly triangular piece of land about 30 kilometers (19 miles) south of the South Island. Rakiura National Park covers about 85 percent of the bright green island. And as the Māori name—Rakiura, meaning “glowing skies”—suggests, it’s a prime location for viewing the aurora australis.
On the northern half of the island, podocarp and hardwood forests featuring coniferous trees with ancient lineages blanket the land. Other areas are covered in shrublands and wetlands, as well as coastal dunes such as those lining Mason Bay. A diversity of birdlife, including the kiwi, populates these relatively untouched ecosystems. The tall trees of the podocarp forests produce various fruits attractive to avian inhabitants, such as bellbirds, with their pure-toned calls, and the rare kākāpō, the world's heaviest and only flightless parrot species.
