The river split into two parts after a flood in 1967.

The lower, northern part of the Waitangitāhuna River is now a 24 km long independent river in the West Coast region on the South Island of New Zealand . After a flood in 1967, the river split into two parts. A name change followed in December 2018. On maps, the river is often referred to as the Waitangitaona River .

geography

Today the river is geographically formed by the confluence of Matainui Creek and Graham Creek and flows in a meandering shape in a wide left curve parallel to the Whataroa River , towards the Tasman Sea , in which it flows.

history

In March 1967, a flood changed the bed of what was then known as the Waitangitaona River . The flood diverted the original river, which previously turned east 1.7 km east of Lake Wahapo , now west and fed from now on to the adjacent lake. A small part of the river also supplied the Graham Creek going east , which flowed into the old riverbed of the Waitangitaona River . Hydraulic engineering measures that took place in the mid-1980s finally ensured that any re-occurring floods could no longer change the river bed. This sealed the division of the river into two parts and, by definition, placed the origin of the lower, northern part of the river at the confluence of Matainui Creek and Graham Creek .

In October 2017, the New Zealand Geographic Board accepted the proposal to rename the lower northern part of the Waitangitaona River to Waitangitāhuna River , as the spelling of the river had been translated incorrectly in the 19th century and should now be corrected. The upper, southern part of the river, however, should be called the Waitakitāhuna-ki-te-Toka River , so that the two rivers, now running independently of each other, could be distinguished.

In another meeting of the New Zealand Geographic Board , the request of the locally based Māori was granted to change the name of the two new parts of the river uniform to Waitangitāhuna River , which happened with the publication in the government gazette on December 20, 2018.
