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 5km (03miles) northwest of Renwick.
In August 2014, the name of the river was officially altered to Ōhinemahuta River.[1] 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.
