The Arahura River is located on the West Coast of New Zealand's South Island. It flows for approximately 30 kilometers, starting in the Southern Alps and emptying into the Tasman Sea. The river is known for its clear waters and scenic surroundings, making it a popular spot for fishing and outdoor activities. The Arahura River is historically significant to the local Māori people, particularly the Ngāti Waewae iwi. The river is associated with traditional stories and practices, including the collection of pounamu, or greenstone, which is highly valued in Māori culture.
