The Shag River has undergone a name change.
The river will now be known as Waihemo Shag River, after the river's name was officially changed by the New Zealand Geographic Board.
Flowing from the Kakanui Mountains, the river is 75km long and meets the ocean at Shag Point, 7.5km east of Palmerston.
The name alteration was proposed by the late Jim Hinkley, and supported by Kāti Huirapa Runaka ki Puketeraki, Te Rūnanga o Moeraki, both Ngāi Tahu Papatipu Rūnanga and mana whenua.
Kāti Huirapa Runaka ki Puketeraki chairman and deputy upoko Matapura Ellison said Hinkley reached out to the rununga for support and it was happy to oblige.
