Pahau River
The Pahau River or Pahu River is a river of the north Canterbury Region of New Zealand's South Island. The river starts in the Tekoa Range,  northwest of Culverden, and flows north before turning south to flow down a long valley between two ridges. At the northern corner of the Canterbury Plains it turns southeast, flowing past the southern outskirt of Culverden to reach the Hurunui River  southeast of the town.
