Where to see New Zealand's wildlife, from North Island sanctuaries to Fiordland, Rakiura and the Subantarctic.
The North Island's best wildlife is on islands and in sanctuaries where introduced predators have been removed or fenced out, so birds that have vanished from most of the mainland, such as takahē, kōkako, hihi and little spotted kiwi, can be seen close up. Sanctuaries are open all year, but spring and early summer (September to December) bring the most song and breeding activity. Island visits have strict biosecurity checks for bags and footwear.
Deep water close to the coast makes Kaikōura one of the few places in the world where sperm whales can be watched almost all year. Further south, Banks Peninsula is the stronghold of Hector's dolphin, and Farewell Spit at the top of the South Island is a major stopover for migrant shorebirds. Whale, dolphin and albatross trips depend on the weather and can be cancelled at short notice, so allow a spare day.
The south-east coast of the South Island holds the mainland's best-known seabird and penguin sites: a northern royal albatross colony at Taiaroa Head, yellow-eyed penguins (hoiho), little penguins, fur seals and New Zealand sea lions. Many of these places are managed viewing areas run by conservation groups or private operators, and some beaches are closed or restricted when birds are breeding, so check before you go and keep to the marked paths.
Wet, forested country on the west side of the Southern Alps and in Fiordland protects wildlife that is hard to find elsewhere: kiwi, Fiordland crested penguins, kea and the alpine specialists of the high country. Weather is changeable and many roads and tracks close in storms or snow, so book flexible plans. Guided night walks and boat trips are the easiest way to see the more secretive animals.
Rakiura / Stewart Island is mostly national park, with forest, beaches and a population of southern brown kiwi (tokoeka) that sometimes feeds in daylight. Further south, the Subantarctic Islands are a World Heritage area of albatrosses, penguins and sea lions that can be reached only by permitted expedition voyages. Landings depend on weather, permits and strict biosecurity checks.
