The electorate was named after a little-known river past Morrinsville, and Tisch was successful in lobbying to have the electorate renamed after the Waikato River.
Mangateparu is a farming service community located close to the west bank of the Piako River, eight kilometres north of Morrinsville in the Waikato region of New Zealand.
Piako River, a river system that drains into the Firth of Thames
The Waitoa River catchment drains the Hinuera Flats and broad southern Hauraki Plains, before converging with the Piako River in the large wetland known as the Kopuatai Peat Dome, northeast of Tahuna.
In the Māori language Tahuna means sandbank, likely to refer to the sandbanks along the nearby Piako River, where a Māori settlement started.
