Fanal Island (73 ha) is the largest island in the Mokohinau Group, Hauraki Gulf, New Zealand. Pacific rats, or kiore, (Rattus exulans) reached these islands between about 1100 and 1800 A. D. Pacific rats were removed from all islands in this group, except Fanal Island, in 1990. An aerial application of Talon 7-20 (containing brodifacoum at 20 ppm) at a nominal rate of 10 kg/ha was made on Fanal Island on 4 August 1997 with the intention of eradicating the rats. Despite heavy rainfall immediately after the poisoning operation, and the fact that baits were not of optimum palatability, the rats were eradicated.
