Another New Zealand island declared rat free19/08/2013 09:20:17 Rodent eradication successful on Taranga Island
July 2013. There has been no sign of rodents on Taranga Island, off the Whangarei coastline north of Auckland, since a large-scale eradication took place there in May 2011. Monitoring has just been completed now that two years have passed since the aerial application of bait. No rodent sign was recorded, which confirms they have been eradicated.
The NZ Department of Conservation (DOC) and Ngatiwai Trust Board worked together on "Project Restore" with the objective of removing the rodent threat to the continued existence and recovery of the many threatened species that live on the island.
Monitoring was carried out in June 2012 and then again in May 2013 using rodent detection methods that consisted of tracking tunnels, rat traps, observations from people working on the island and rodent detecting dogs scouting the island. DOC Programme Manager Keith Hawkins says "After two years of no kiore (Pacific rats) being found we are confident that the eradication was successful. Two years allows for any kiore that may have survived the bait drop to have bred to detectable levels and be picked up by monitoring".

Taranga has extensive historical features and holds spiritual significance. Taranga Island is part of the Hen and Chicken Islands group and is ranked as internationally important. As a nature reserve, Taranga is strictly a 'no landing zone' to protect the rare and endangered flora, fauna and local endemics that are present on the island.
Now the island is kiore free, DOC urges boaters to be extra vigilant, ensuring they are not taking unwelcome guests out with them as that is the only way they can get there. Not storing food on your boat and having traps set on board are easy measures that can be taken.
