The story behind it
The Waikato starts high on the volcano Ruapehu, rests for a while in Lake Taupo and then pushes north through green farmland. Its name means flowing water in the Maori language, and for the Maori people it is a tupuna, an ancestor, not merely a river. In 2017 the neighbouring Whanganui River was even given the legal rights of a person, which shows how seriously rivers are taken in New Zealand. Along the Waikato stand many dams; their power stations light the city of Hamilton and much of the North Island. Steam rises near the banks where hot springs bubble out of volcanic ground. Trout swim in the clear upper reaches, black swans paddle in quiet bays, and rowing crews train on the wide, calm stretches below.
Questions children ask
How long is the Waikato?
The river is about 425 kilometres long. That makes it the longest in New Zealand, although the country has many rivers. Its whole course lies on the North Island.
Which country does the Waikato flow through?
It flows entirely through New Zealand, on the North Island. Its route leads from the volcanic highlands past Hamilton to the west coast. No other country shares this river.
Where does the Waikato end?
It ends in the Tasman Sea at the settlement of Port Waikato. The mouth is guarded by long black sand bars and strong surf. Swimming is dangerous there, but seabirds love the place.
