The Avon River is a river at Christchurch, New Zealand. It is known by the Maori as Otakaro or Putare Kamutu. It was named Avon by John Deans in 1848 after the River Avon, Falkirk, Scotland. It flows all year round, obtaining water from artesian sources. It flows into the Pacific Ocean via an estuary near Sumner.
