The Little River is a tributary of Rakaia River, about 7 km (4.3 mi) long, in the Canterbury Plains of New Zealand's South Island. It rises on the 2,185 m (7,169 ft) Mount Hutt and enters the Rakaia 314 m (1,030 ft) above sea level.[1]

Little River is also the name of a short river, roughly 2 km (1.2 mi), on Stewart Island,[2] about a 2-hour walk from Oban.[3]

Wairewa marae, a marae (tribal meeting ground) of Ngāi Tahu and its Wairewa Rūnanga branch, is located at Little River.[4] It includes Te Mako wharenui (meeting house).[5]

Power station

MainPower’s Cleardale power station, was built in 2010. It takes up to 450 L (99 imp gal; 120 US gal)/second[6] through a fibreglass penstock,[7] 2.3 km (1.4 mi) up from,[6] and 300 m (980 ft) above,[8] the station, to drive a 1 mW (1.3×10−6 hp) pelton wheel.[6] Power is generated at 400 volts and transformed to feed into Electricity Ashburton's 11 kV network.[8] Some water from the tailrace is used to irrigate 208 ha (510 acres),[9] with the remainder returned to the river.[6] The power station and penstock have been landscaped[10] and are now barely visible.[11]
