This is something all our editors have campaigned against for several years now and many articles have been posted and published in various places showing it does a lot more harm than good. There have also been several on Waikanae Watch (use the search box to find them). Poisonings in the Tararua Range have happened recently. It’s something that some (although not all) Maori iwi are fierecely opposed to, including Ngatiawa ki Kapiti which has sizeable landholding in the Waikanae/Reikorangi hinterland in the Tararua Range.
It’s something that should be asked of the candidates for the Kapiti seat on the Greater Wellington Regional Council. KCDC is not involved.
