Wild Kiwi Predator Management and Welfare

Kiwi face existential threat from introduced predators, and predator control programs are essential for their welfare and survival in New Zealand.

Key Facts

Kiwi populations declined by 94% following introduction of cats, stoats, rats, and possums
Without intervention, 95% of kiwi chicks die before reaching adulthood
Kiwi are nocturnal and flightless, making them highly vulnerable to mammalian predators
Operation Nest Egg removes eggs from the wild for incubation, releasing juveniles at predator-free size
1080 aerial drops and ground trapping programs reduce predator density across large areas

Welfare Considerations

Kiwi chicks attacked by stoats experience traumatic deaths as the predators target the head. Stoat population irruptions following beech mast events can kill entire cohorts of chicks across large areas. Adult kiwi caught by dogs suffer serious bite injuries that cause prolonged suffering and often fatal infections. Predator control interventions, while creating some welfare harms for the target pest species, prevent immeasurably greater suffering for vulnerable kiwi across their range. The welfare math strongly supports intensive predator management given the scale of kiwi population decline.

What You Can Do

Support Predator Free 2050 New Zealand through donations and advocacy
Participate in local kiwi recovery programs and predator trapping networks
Keep dogs leashed and away from kiwi habitat, especially at night
Donate to Kiwis for kiwi which funds predator control and Operation Nest Egg
Advocate for continued government funding of aerial 1080 operations which protect kiwi at landscape scale
