The next phase of a major pest eradication operation has started on Kawau Island, with Auckland Council and its partners working closely with landowners and residents to remove invasive wallabies and possums threatening the island’s native forest.
The ground-based operation, launched in early May, began in the southern part of the island and is gradually progressing northward. Trained hunters, supported by indicator dogs and thermal drones, are conducting the primary pest removal.
In areas where high populations persist, targeted toxins – specifically 1080 and Feratox – are being introduced and this was due to start last week, weather permitting. The use of toxins will follow strict conditions set by the National Public Health Service.
The programme is removing introduced species, which are devastating seedlings and native plants, and destroying vital habitats and food sources for indigenous wildlife. The long-term goal is to restore the island’s ecosystem by creating a pest-free sanctuary.
Safety Measures in Place
Auckland Council has emphasised that public safety remains a top priority.
“All toxin applications are guided by robust health and safety protocols,” a spokesperson says. “Warning signs will be in place, and visitors must strictly avoid touching or consuming any baits.
“In the event of accidental ingestion, call 111 and contact the National Poisons Centre immediately.”
Dogs are particularly vulnerable to 1080 poisoning if they consume baits or scavenge carcasses, and council is strongly advising that visitors keep their dogs off the island during the operation. Residents must keep dogs on leashes and under close supervision at all times.
In collaboration with Warkworth Vets, free muzzles and emetic medication are available for Kawau residents. The clinic is also prepared to treat any dogs affected during the eradication period.
While uneaten bait will be removed shortly after deployment, the risk of secondary poisoning for dogs will remain for up to six months. Signage and monitoring will remain in place throughout this period.
Council is targeting the months of July and August to complete the toxin operation in the south and then August and September to wrap up the toxin operation in the north.
