Those possum where their in NZ before humans came along, big tuff wallies man and his gun.
Sorry do you have interlectual issues apart from the inability to spell and compose a sentence, Grey Possum was introduced into NZ from Australia and is 1000% non native noctious species, due to its appetite for native birds eggs amoungst other things. So the Government poisons them and cars run over them and we do our part, sort of a Kiwi Cane Toad but much cuter.
The Air Ranger costs about the same price as a VMX bike and takes care of them nicely.
