Their Story

The arrival of kiwi pukupuku at Brook Waimārama Sanctuary marks a major conservation milestone. In May 2025, 41 kiwi were successfully translocated — the first time in over a century that this taonga species has roamed free in the Nelson region. Since then, their calls have echoed through the valley after dark.

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 South Westland in late 2025 with chicks sighted in early 2026.

Population

The population of kiwi pukupuku is estimated at around 2,000 to 2,100 individuals. Kapiti Island has around 1200 kiwi, with the rest on other pest-free islands and sanctuaries. Recently, a small mainland population was discovered in South Westland with less than a dozen adults. The Sanctuary hosts a small growing population with the capacity to hold around 300 kiwi

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 pest-free islands and sanctuaries. The Brook Waimārama Sanctuary provides the only secure mainland habitat for them in Te Waka A Māui (the South Island). 

Classified as Threatened – Nationally Increasing, kiwi pukupuku rely entirely on pest-free refuges. Larger kiwi when at a certain size are resistant to predation from stoats. Kiwi pukupuku however, remain vulnerable to stoats even as adults, and are especially vulnerable to dogs. Long-term success depends on maintaining pest-free status of sanctuaries and islands, establishing new populations and maintaining genetic diversity

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.

In May 2025, the Sanctuary welcomed 41 kiwi pukupuku and we have already seen evidence that breeding is going well. Learn more about their incredible journey and the many people involved in bringing these kiwi birds home to Nelson.
