New Zealand's native birds are reaping the benefits of aerial 1080 operations.

The Department of Conservation says a recent 1080 drop over Northland's Russell Forest has been even more effective than anticipated.
In September Newshub Nation attended the aerial pre-feed operation, where baits not laced with poison were dropped so that rats and possums got used to feeding on them.
​
This meant a few weeks later, when the baits containing 1080 were dropped, they decimated the rat and possum populations. Nearly all the rats have been wiped out and 80 percent of the possums have been killed according to DOC monitoring.

The Department of Conservation (DOC) says the 1080-poison drop on Northland's Russell State Forest has proven an outstanding success.

The Environmental Protection Authority will investigate a 1080 drop which left eight cattle dead in the Waikato.

When I last visited a forest frequented by orange-fronted parakeet/kākāriki karaka, there was quiet optimism.
