Waiau River, Hikuwai River, Uawa River are three names for the same river. Three sections are named differently in the order mentioned.

The Uawa River , called the Hikuwai River in the middle and in the upper course from the source from the Waiau River , is an approximately 50 km long river in the Gisborne region on the North Island of New Zealand .

geography

The river rises as the Waiau River in Waingaromia , about 11 km west of Mount Tutamoe and 4 km north-northwest of the settlement of Tauwhareparae at an altitude between 500 and 600 m, then flows first in an easterly direction and then continues in a semi-arc in a north-easterly direction to the small one Hikuwai locality . From here, the river is Hikuwai River called and moves meandering manner towards the south to near the settlement Mangatuna and from the mouth of the Mangatokerau River in the Hikuwai River from then uawa river called, to its confluence with the Pacific Ocean in Tolaga Bay . The estuary is about 54 km northeast of Gisborne .

Tolaga Bay with the place of the same name , Uawa River and Tolaga Bay Wharf (quay)

The different naming of the river is due to the identity of the Māori , for whom the river next to the place where they lived was very important. The village, the area and the river were often named the same (see example Uawa , Uawa River, Hikuwai and Hikuwai River).

Floods

Hikuwai River, 7 days after extreme rainfall

In the section of the Hikuwai River and the Uawa River, there is always the threat of flooding when it rains extremely heavily. The Hikuwai can then rise from 1.5 m normal water level to 10-12 m height. The highest level documented so far at 14.37 m was caused by cyclone Bola on March 7, 1988. A step-by-step evacuation plan comes into force from 11 m.
