First South Island Tuatara hatchlings in hundreds of years

Two tuatara hatchlings have been sighted at the Orokonui Ecosanctuary near Dunedin. They're the first to be seen since adult tuatara were released at the ecosanctuary eight years ago. It's thought tuatara haven't thrived in this part of the world for eight hundred years. Kathryn Ryan speaks with Professor Alison Cree, Otago University's Department of Zoology, whose team made this exciting discovery.
