Taumarunui is a town in Ruapehu District on the North Island of New Zealand. The town is the administrative center of the district. The name Taumarunui is attributed to the last words of Māori chief PEhi Taroa - taumaru called a screen and nui big, so literally big screen, which is to protect him from the sun. Another derivation refers to a large screened area where the kumara is grown.
