Ōhinemahuta River

The Ōhinemahuta River, formerly known as the Onamalutu River, is a river of the Marlborough Region of New Zealand's South Island. It initially flows northeast, turning southeast to reach the Wairau River 5 km northwest of Renwick.

In August 2014, the name of the river was officially altered to Ōhinemahuta River. The former name of the river, Onamalutu, was a corruption of Ōhinemahuta, which refers to the place where the Rangitāne/Ngāti Mamoe ancestor Hine Mahuta once lived.
