Lynda Topp, one half of iconic comedy duo the Topp Twins, takes a journey along the mighty Waikato. From Port Waikato all the way to the river's hidden source outside Taupō, Topp makes frequent stops en route — including to interview Ginette Roose, daughter of Caesar Roose, a pioneer in modern commercial use of the waterway. Topp also explores some of the river's Māori history, dropping in at Rangiriri and Taupiri maunga, and meeting Eva Rickard. Whether steering the Olympic women's rowing eight, or getting up close with the torrid Huka Falls, Topp finds a good old cuppa at every bend of Aotearoa's longest river.
