Raoul Island is the largest and northern-most of the Kermadec Islands. It is the above water part of a large, underwater caldera, and has an active volcanic crater. Alison Ballance joins Department of Conservation threatened plant specialist Peter de Lange for a walk on the track to Denham Bay, high above the crater lakes, to find out about the island’s native plants, where they have come from and how they coped with many years of goat browsing and seed predation by rats.
