Off the beaten track with Kennedy Warne

Today Kennedy joins Kathryn to talk about how technology is being harnessed in the fight against New Zealand's pests and predators. He's been looking at eradication projects in Northland, including Bay Bush Action, which is trying to free 2500 ha of Opua State Forest of predators, and Backyard Kiwi, which has been targeting stoats - and might be contributing to the health of kauri in the area in the process.
