"Ngatokimatawhaorua is one of the world’s largest Māori ceremonial war canoes. The canoe is launched every year as part of the annual Waitangi Day celebrations. At 35.7 metres long, up to 2 metres wide and weighing 12 tonnes, the vessel is a striking sight as it glides on the water laden with up to 80 paddlers and 55 passengers."
