It is an important place to Māori for the resource of pounamu (greenstone), only found in a few places in the South Island of New Zealand. When the region was sold to the British Crown in 1860 by the chiefs of Poutini Ngāi Tahu the rights to pounamu on the Arahura River were meant to be retained, these rights were ignored in the deed (Arahura Deed). In 1990s Ngāi Tahu and the government negotiated for ownership of pounamu from the river to be restored and this was settled in the Ngāi Tahu (Pounamu Vesting) Act 1997.^[5][6][7]

The lower reaches of the Arahura River were a major producer of gold in the past – and extensively mined, but are now worked out.

The historic Arahura road/rail bridge. It was replaced in 2009.

In 2009 the 120-year-old dual road/rail bridge across the river was replaced. Sections of the old bridge were reused elsewhere on the rail network and one complete span was retained for a local heritage park.^[8]

The river is the subject of a 2016 song of the same name by Marlon Williams.
