Taborsky, M. (1988). Kiwis and dog predation: observations in Waitangi State Forest. Notornis, 35(3), 197-202.
A wild dog was found to kill 13 out of 23 kiwis marked with transmitters.
The whole population may have lost 500 out of 900 birds, although this estimate may be conservative. The population will probably need 10-20 years and a rigorous protection scheme to recover to previous densities
