The Waimakariri River is one of the largest rivers in Canterbury, New Zealand. It is on the eastern coast of New Zealand's South Island. It flows for 151 kilometres (94 mi) southeast from the Southern Alps across the Canterbury Plains to the Pacific Ocean.

The river is a fine example of a braided river. As the photograph shows, for much of its upper reaches, the river is braided. It runs across wide shingle beds. As the river approaches the Canterbury Plains, it passes through a belt of mountains. There it is forced into a narrow canyon (the Waimakariri Gorge). Then it goes back to its braided form across the plains. It enters the Pacific north of Christchurch, near the town of Kaiapoi.

Most New Zealand river beds are unoccupied crown land, but the bed of the Waimakariri River is looked after by the Canterbury Regional Council (Environment Canterbury).[1]
