Northland was once covered in magnificent kauri forests – but almost all were logged after Europeans arrived in New Zealand. Felling the giant trees was dangerous work, and dams were built so the logs could be floated down rivers. Today a museum at Matakohe showcases the history of kauri forests and their exploitation.
