Rotorua predator control projects have the chance to win $2500 for providing information on their work to Predator Free NZ.
The cash prize will be awarded to an established predator control group or entity that provides details of its location and target species before May 22.
"Across New Zealand community groups, hapu/iwi and private landowners make a huge contribution to predator control," said Partnerships Ranger Caraline Abbott.
"This is an opportunity for their hard work to be marked on a map so that Rotorua can be represented on a national map of predator control.
"Locally we've seen great results produced from landowners and groups who have dedicated themselves to controlling predators that have the potential to decimate native bird populations and destroy native forests."
