The Department of Conservation has been forced to issue a warning to visitors to national parks, NZ Herald reports, after staff found Aucklanders carrying pet cats up Mt Taranaki in backpacks. “Bringing a pet into the park may seem a harmless thing to do,” DoC senior ranger Dave Rogers said, “but it has potentially deadly consequences for our native wildlife.” DoC advised that no pets are permitted in National Parks or dog prohibited areas unless express written approval is granted. Those flouting the rules face an instant infringement fine of up to $800.
