Stewart Island's Ulva Island Bird Sanctuary is a remarkable oasis of native flora and fauna. Located in Paterson Inlet, just off Stewart Island’s coast, this predator-free sanctuary provides an idyllic setting for New Zealand’s rare and native bird species to thrive. Managed meticulously to remain free of introduced pests, Ulva Island offers an experience that is nothing short of magical for bird watchers and nature lovers alike.
The sanctuary is a rare gem for viewing native birds in their natural habitat. Ulva Island’s lush forests, featuring towering rimu, totara, and matai trees, are home to an impressive array of avian species that have become difficult to find elsewhere in the country. One of the most sought-after sightings here is the Stewart Island brown kiwi, or Tokoeka, a nocturnal bird with endearing habits that can sometimes be spotted during daylight hours. Lucky visitors may also encounter yellow-eyed penguins, one of the rarest penguin species in the world, which occasionally make an appearance on the island's quiet beaches.
Other birds you’re likely to encounter include the curious weka, kākā (forest parrots), tūī, and the vibrant green kākāriki (parakeet). Ulva Island also serves as a sanctuary for the South Island saddleback and the Stewart Island robin, both of which have seen population declines elsewhere but flourish here due to the absence of predators. The island is a paradise for hearing the harmonious songs of bellbirds and tūī echoing through the forests, which adds a soothing soundtrack to any hike.
For those exploring Ulva Island, there are well-maintained walking trails offering various levels of accessibility, from easy walks to more immersive treks. Guided tours are also available and are a popular choice, as experienced guides provide insights into the island’s unique ecosystem, the history of conservation efforts, and the complex relationships between native plants and animals. They help spot and identify birds you might otherwise miss and can share the cultural significance of the area as a former Maori hunting ground and a source of prized native timber.
In addition to its natural beauty, Ulva Island reflects New Zealand’s dedication to conservation. Efforts to keep the island predator-free have led to successful breeding programs for endangered bird species, helping ensure their survival. Visitors are encouraged to respect the island's strict biosecurity measures, such as checking for seeds and dirt on shoes, to help maintain the sanctuary’s pristine environment.
