Dog owners are being urged to keep their pets out of kiwi zones after four dogs were seen wandering inside Opua Forest in Northland.
The Advocate saw the dogs - two male, two female, all without collars and apparently unregistered - well inside the forest on Sunday afternoon. They were about 1km up a track from School Rd in Paihia to a lookout point.
Craig Salmon, of the conservation group Bay Bush Action, said owners needed to make sure they knew where their dogs were at all times and not just let them off the lead for exercise.
"If they're roaming the bush in a pack, we'd be really, really concerned - especially with kiwi already on their last legs, and all the effort we're putting into pest control in Opua Forest."
In 1987 a single dog lost in Waitangi Forest for six weeks killed more than 500 kiwi, Mr Salmon said.
