Dream team for Coromandel kiwi
Predator control and community effort a winner
Brown kiwi are thriving in Eastern Coromandel as sustained predator control efforts by the Department of Conservation and the local community pay off for the threatened birds.
Surveying of kiwi in the area between Tairua and Hot Water Beach has shown a 10 per cent increase from 2015 to 2020.
Numbers are expected to continue to increase following the recent distribution of biodegradable 1080 bait pellets at Whenuakite, which will provide further protection from stoats for kiwi.
Whenuakite Kiwi Care Group spokeswoman Janice Hinds says the area’s kiwi benefit from a combined predator control approach.
“We have an amazing crew of landowners who contribute to on-ground predator control, covering 3500 hectares.
“Then, every three to four years, the Department of Conservation and Waikato Regional Council apply 1080 bait — cleaning up the possums destroying the canopy, and the trap-shy rats and mustelids we miss.
“The difference is extraordinary.”
The Coromandel has a long history of environmental protection
and conservation work, much of it focused on species found in its expansive forests.

Leon Pickering says vulnerable brown kiwi are a particular focus of the aerial predator control programme.
“We know that kiwi chicks
are especially at risk — with up to 95 per cent of chicks being killed by predators in some locations.
“Sustained predator control, a paired system like this, means around 60 per cent of the chicks make it to adulthood.”
Monitoring has shown the recent aerial 1080 operation in Whenuakite reduced rodent populations to an undetectable level.
Stoats have also been controlled, at a rate of 90 to 100 per cent on average, through secondary poisoning as they feed on rodent carcasses.
While kiwi are more active at night, Janice says during the day there are further signs of the biodiversity gains from the programme.
“We’ve seen flocks of kereru¯ — up to 250 at a time, and the tomtits are spreading up from the South. We’ve seen po¯hutukawa trees flower for the first time in a lifetime.”
Leon says the support of the community has been critical to achieving this success.
“We’ve had landowners coming across kiwi in their backyards — they’re seeing the results. More and more are coming to us and asking to be involved.”
Whenuakite Kiwi Care Group is in it for the long haul.
“Dad [Arthur Hinds, 1946-2017] was involved from the early days, and now it’s a family thing — we just got our 21⁄2-year-old grandson some tramping boots. That’s some succession planning!”, says Janice.
“We would like to thank Save the Kiwi and Waikato Regional Council for their financial support to keep our work going.”
Whenuakite kiwi, and the whole forest ecosystem around them, are in good hands.
