WARNING – 1080 possum carcasses, Ōrongorongo River

23 September 2025 – Heavy rain overnight may have washed possum carcasses, poisoned with 1080, down the Ōrongorongo River following the recent 1080 operation in the Wainuiomata-Ōrongorongo Forest. We urge dog owners to keep their dogs away from the Ōrongorongo River and Wainuiomata Beach until council staff have checked for, and removed, dead possums poisoned with 1080. People are not at risk from poisoned carcasses.

This warning may be in place for up to four months.

If you’re a dog owner or walker, it’s good to know the risks that you might come across in our region’s outdoor spaces, and how you can prepare for them. Even the most well trained dog is likely to scavenge, or could eat something that might harm them.

We take risks to dogs very seriously, so we have put together some tips and resources you can use to keep your dog safe in our region’s parks, reserves and waterways.

For information on dog owner responsibilities, public exercise spaces, lost and impounded dogs, and reporting dog attacks, please contact your local council.
