Amazing Species: Northern Brown Kiwi
The Northern Brown Kiwi, Apteryx mantelli, is listed as Endangered on the IUCN Red
List of Threatened Species™. Once widespread throughout the North Islands and northern
South Islands of New Zealand, this species now only survives in isolated and fragmented
populations, with unmanaged mainland populations declining at a rate of about 2.5% per
year.

Currently, the most significant threat to the survival of the Northern Brown Kiwi is the
predation of adult birds by dogs and ferrets, Mustela furo, and the predation of young
birds by introduced predators such as stoats, Mustela erminea. The clearance of habitat
fragments continues to threaten small populations of this species, while new avian diseases
are also a potential threat.
Conservation measures for the Northern Brown Kiwi currently underway include intensive
monitoring, involving radio-tracking and bird banding, as well as predator control. In 1995,
a dedicated rearing facility was constructed to conduct Operation Nest Egg (ONE), an egg
incubation and captive rearing programme. Further proposed conservation actions include
pest control, conservation education programmes and promotion of legislative changes.
