Matahiwi is a farming community 55 kilometres (34 mi) upriver from Whanganui, New Zealand, home to the Māori hapū known as Ngā Poutama of the iwi Te Āti Haunui-a-Pāpārangi. The township takes its name from the bush-clad puke (hill) on the western side of the Whanganui River, right above the local marae, whose name translates as "the face on the ridge" (mata, face; hiwi, ridge).
