On Wednesday, a contractor working on Invercargill's museum demolition spotted a baby tuatara in an area formerly used for the animals. The baby tuatara was about the size of a little finger and blended into the dirt, he said. This week's discovery precedes the opening of a new tuatara enclosure at Queens Park animal reserve on 8 June. The new facility will house 18 tuatara, meaning the council will need to look at other homing options for the newly discovered babies.
