Waikato river is clam right here but that will change
The Waikato River is the longest river in New Zealand. Its catchment covers 14,260 square km or 12 per cent of the area of the North Island. The river starts its journey to the sea from high in the central North Island volcanic zone, 2797 metres above sea level.
From there it flows into Lake Taupo. Leaving the lake, the river cuts through the volcanic plateau flowing north, passing through eight hydro electric dams, and onto the lowlands from Cambridge to Mercer.
The river finally flows into the Tasman Sea at Port Waikato after a journey of 425 km from Lake Taupo.
The Waikato River is a tupuna (ancestor), a taonga (treasure), and the mauri (life force) of Tainui Waka and Ngati Tuwharetoa.
