Status key Explanation Further information
Consultation OSPRI consults widely with landowners and land users affected by TBfree operations. The timing and boundaries of all aerial operations are published annually to allow affected parties to have their say on how operations are undertaken  Annual national consultation
Operational Planning The planning process includes consulting with iwi, landowners and government agencies regarding access and identifying any exclusion areas. It also includes stakeholder meetings and Ministry of Health (MOH) consenting processes Operational planning graphic
Notification Ahead of any aerial operation, contractors undertaking the work will notify all affected landowners and land users personally or through published notices. Aerial Ops: need to know
Pre-feed The target area is pre-fed with non-toxic cereal baits. Pre-feeding familiarises possums with the baits and encourages them to find more of the same. Aerial operation safety 
1080 applied - treated area under caution Signs communicating the risks to people and to dogs when entering the operational area are placed at all likely access points. Key public tracks are checked as required by consent conditions, and any required water monitoring is completed. Warning signs will remain in place until the operation reaches the "Operation complete" status. 1080 possum control factsheet Keep your dog safe
Operation complete Warning signs removed.  Please check guidance from the Ministry for Primary Industries and Department of Conservation before resuming normal activities, such as food gathering. Once an aerial operation is complete, a range of post-operational activity takes place. The first significant rain breaks down any residual baits into harmless substances and tracks or other areas of high public use within the baited area are checked and cleared. The post-operation period will depend on weather conditions and the rate at which bait and carcasses have broken down. Then warning signs can be removed.  Find out more in our After the Drop: What Happens Once Toxic Baits are on the Ground factsheet. Post operational factsheet TB information for Hunters
