The Huriwai River is a river of about 9km (06miles) in New Zealand's North Island. It rises in rough hill country to the southeast of Port Waikato, flowing west to reach the Tasman Sea 5km (03miles) south of the mouth of the Waikato River. The main tributary is the Mangapai Stream.[1]
The river has a waterfall in its upper reach, at the boundary of sandstone and conglomerate rocks.[2] Just north of the river's estuary, the Jurassic rocks have been described by the Geological Society as containing, "amazing fossil leaves and ferns".[3]
At the point where the river is crossed by Waikaretu Road, its water quality is in the lower 50% for macroinvertebrates.[4]
