Waimakariri River

The Waimakariri River, formerly briefly known as the Courtenay River, is one of the largest of the North Canterbury rivers, in the South Island of New Zealand. It flows for 151 kilometres (94 mi) in a generally southeastward direction from the Southern Alps across the Canterbury Plains to the Pacific Ocean. In Māori, Waimakariri has several meanings, one of which is "river of cold rushing water". The river is known colloquially in Canterbury as "The Waimak".
