Note:  Brodifacoum is a serious rat poison, an anti-coagulant which kills the things that eat it over a long period of time. It has secondary by-kill on animals / things that eat things that have been killed by it.  Instead of slathering poison everywhere it’s time surely that NZ considered eco friendly extermination of pests, given our clean green classification is long gone. So also is our edible wild food. And not only were all the wekas exterminated at Tawhitinui Island, but the following also:

• Nearly 60% of the Tawharanui Regional Park dotterel population died through eating brodifacoum baits and poisoned sand-hoppers (2004)
• Brodifacoum residues continued to be found in wildlife more than 24 months after the brodifacoum poison drop in and around the Rotoiti Nature Recovery Project in Nelson (2005)
• The Rangitoto and Motutapu Island eradication by-kill included dolphins, penguins, fish, numerous dogs and birds
• Vast numbers of dead mussels
