Rakaia is a town sited on the southern banks of the Rakaia River on the Canterbury Plains in New Zealand's South Island, approximately 57 km south of Christchurch on State Highway 1 and the Main South Line. Immediately north of the township are New Zealand's longest road bridge and longest rail bridge, both of which cross the wide shingle beds of the braided river at this point. Both bridges are approximately 1,750 metres (5,740 ft) in length.[citation needed]
Rakaia was also the junction of the Methven Branch, a branch line railway to Methven that operated from 1880 until its closure in 1976. An accident at the railway station in 1899 killed four people.
Rakaia's most obvious feature is a large fibreglass salmon. The river from which the town takes its name is known for its salmon fishing and jetboating. In 2025 the sculpture was temporarily moved to the workshop of its creator Phil Price for restoration.
The town and river were previously known as Cholmondeley, but the Māori name would eventually prevail over the English one.
The rural community of Acton is located south of the Rakaia township.
Rakaia is described by Statistics New Zealand as a small urban area and covers 11.30 km2 (4.36 sq mi). It had an estimated population of 1,680 as of June 2025, with a population density of 148.7 people per km2.
