Kiwi pukupuku
Little Spotted Kiwi
Apteryx owenii
Their Story
The Brook Waimārama Sanctuary is home to 41 kiwi birds translocated in May 2025 and their new chicks from the current breeding season (not yet counted). They are the smallest of the five kiwi species. Formerly widespread on both main islands, but now mostly confined to offshore islands and mainland sanctuaries. Flightless, with tiny vestigial wings and no tail. Nocturnal, therefore more often heard than seen. Male gives a repeated high-pitched ascending whistle, female gives a slower and lower pitched warbling whistle. Light brownish grey finely mottled or banded horizontally with white, long pale bill, short pale legs, toes and claws.
The best way to get a chance to see a kiwi bird in Nelson is on one of our Night Tours – you’re almost guaranteed to hear them calling to each other and if you’re lucky might catch sight of one foraging in the bush (see the video below of one tour attendee’s exciting discovery!)
Conservation Status

Endemic – Nationally Increasing
Endemic to New Zealand, this smallest of the kiwi species is found mainly on offshore islands (particularly Kapiti Island where the Sanctuary birds were translocated from) and mainland sanctuaries. A small remnant population was discovered in Fiordland in late 2025 with chicks sighted in early 2026.
Population

The population of kiwi pukupuku (little spotted kiwi) is estimated at around 2,000 to 2,100 individuals, primarily living in predator-free sanctuaries like Kapiti Island, with smaller populations on other islands and recent exciting discoveries of a small, breeding mainland population in South Westland. The Sanctuary hosts 41 adult kiwi pukupuku and an as yet uncounted population of chicks from the current breeding season.
Voice

Male gives a high-pitched ascending whistle, female gives a slower and lower pitched ascending trill; both sexes repeat calls 25-35 times per sequence.
Food

Little spotted kiwi eat mostly small invertebrates, especially earthworms; larvae of beetles, cicadas, flies and moths; spiders, adult beetles and some small fallen fruit and leaves.
Kiwi pukupuku are the smallest of New Zealand’s five kiwi species, standing about 25 cm tall and weighing around 1.3 kg. Their soft grey-striped feathers resemble fur, and they have long, pale beaks with nostrils at the tip — giving them an excellent sense of smell. Both sexes look alike, though females are larger with longer bills.
Nocturnal, kiwi pukupuku emerge after dusk to forage for earthworms, beetles, larvae, and other invertebrates. They use their sensitive beaks to probe the soil and leaf litter. Their presence is often revealed by the sound of rustling, loud calls, or footprints left in damp earth.
Kiwi pukupuku form lifelong pairs and defend small territories of a minimum of three hectares. Females lay one to two large eggs per clutch, incubated by the male for 65–75 days. Chicks hatch fully feathered and independent, though they remain near the burrow for several days. The maximum lifespan is uncertain, but kiwi pukupuku can live for 40–50 years.
Once widespread across much of Aotearoa, kiwi pukupuku almost disappeared completely from the mainland by the early 1900s due to predation by stoats, dogs, and cats. They now survive on a handful of predator-free islands and sanctuaries. The Brook Waimārama Sanctuary provides the only secure mainland habitat for them in Te Waka A Māui(the South Island). A small remnant population was discovered in Fiordland in late 2025 with chicks sighted in early 2026.
Classified as Threatened – Nationally Increasing, kiwi pukupuku rely entirely on predator-free refuges. Their slow breeding and ground-nesting habits make them especially vulnerable to introduced mammals. Long-term success depends on maintaining pest-free status of sanctuaries and islands, establishing new populations and the introduction of rare genetics into new populations.
In partnership with Ngāti Toa, Forty-one kiwi pukupuku were released in May 2025, establishing the Sanctuary’s founding population. Their nightly calls are now a treasured part of the Brook soundscape, and lucky visitors can occasionally spot them on guided night tours. With continued pest-free conditions, this population is expected to grow to over 300 birds.
Kiwi pukupuku were the first kiwi species successfully translocated to predator-free islands.
