The river drains the western flanks of the Tararua Ranges around Reikorangi and the Akatarawa Valley, then passes to the south of the town of Waikanae before entering the Tasman Sea at Waikanae Beach. Tributaries include the Maungakotukutuku Stream, Ngatiawa River, and Reikorangi Stream. The estuary of the river is a significant reserve providing shelter and habitat for local and migratory seabirds. It also provides a major recreational location, both for residents and tourists.

Water up to a maximum amount is taken out of the river as water supply for Waikanae and Paraparaumu. This sometimes leads to water restrictions if the river runs low, however in January 2005 the river burst its banks after heavy rain. The river has good water quality and high aquatic biodiversity, but there are occasional blooms of toxic cyanobacteria after prolonged periods of low flow during hot, dry weather.
