Southern Tararua & Project Kaka Aerial Pest Control Operations

EcoFX (Rentokil Initial) wishes to advise the public of its intention to aerially apply the toxin Sodium Fluoroacetate (1080) for the purpose of controlling pests in the Southern Tararua ranges.

The Southern Tararua operation is being undertaken as part of OSPRI New Zealand’s TBfree programme to protect local farms from tuberculosis infection. The Project Kaka operation is at the Northern end of OSPRI’s TB Management Area in Southern Tararua, OSPRI NZ is managing the Project Kaka operation on behalf of the Department of Conservation (DOC).

Control Area:

The Southern Tararua Ranges north of the Remutaka Hill Road (SH2), east of Akatarawa Road, south of Tarn Ridge Hut, west of Greytown. A map of the treatment area may be viewed on the OSPRI website:

Commencement Date:

The operation will commence with the application of non-toxic cereal pre-feed pellets beginning on the first day of favourable weather from early February 2026. At least 5 days following the completion of pre-feeding, in the next suitable weather window, the application of cereal pellets containing 1080 will commence.

Southern Tararua Bait Description:

Pre-feed: Cereal based pellet, approximately 16mm in diameter, brown in colour.

Toxic bait (Sodium Fluoroacetate (1080): Cereal based pellet, approximately 20mm in diameter & dyed green).

Project Kaka Bait Description:

Pre-feed: Cereal based pellet, approximately 16mm in diameter, brown in colour.

Toxic bait (Sodium Fluoroacetate (1080): Cereal based pellet, approximately 16mm in diameter & dyed green).

Managing risk

1080 is poisonous to humans, domestic and game animals. In areas where the toxin has been applied, dogs are highly at risk until poisoned carcasses have disintegrated. This takes four-to-eight months or longer.

There will be warning signs placed at entrances to the treatment area immediately prior to the operation.

Risks can be eliminated by following these rules:

• DO NOT touch bait

• WATCH children at all times

• DO NOT EAT animals from this area or within the buffer zone outside the treatment boundary. The buffer zone is 2 km for deer and pigs, 200 m for rabbits, and 1 km for hares and possums.

• Poison baits or carcasses are DEADLY to DOGS

Observe these rules whenever you see warning signs about pesticides. These signs indicate pesticide residues may be still present in baits and poisoned carcasses. When signs are removed, normal activities can resume. If in doubt, check with your local OSPRI office. Please report suspected vandalism or unauthorised removal of signs.
