The Waikato is a region of the North Island of New Zealand that lies to the south of Auckland and is named for the Waikato river, that traverses its length. The Waikato river has several hydroelectric dams and the manmade lakes behind them are used for a range of water sports.
This area of New Zealand is partly agricultural, with dairying being the major agri-industry.
