The Manawatū River in New Zealand's North Island offers several distinct paddling sections ranging from Grade 1 to Grade 2 under normal conditions, making it accessible to recreational paddlers and those training for multisport events. The Manawatū Gorge section is rated Grade 2 and is largely flat water with a few manageable features, suitable for a relaxed float. Below the gorge, from Ashhurst through to Opiki and continuing toward Palmerston North and Foxton, the river is predominantly flat water and is regularly used for multisport training. The river ultimately flows out to the Tasman Sea near Foxton.

The primary hazards on the river are strainers in the form of logs and willow trees. Logs are a particular concern on the Ashhurst to Opiki section, and both logs and willows require attention on the stretch down to Ballance. Paddlers should be vigilant for these obstacles throughout the lower sections. When the river is in flood, conditions change significantly — the river can rise to Grade 4, and rescue of a capsized paddler becomes extremely difficult. In flood conditions, the river is recommended only for advanced kayakers.

Flow information is available through the Horizons Water Line at 0508 435-663, which is a useful resource for checking conditions before heading out. Near the river mouth at Foxton, a boat ramp is available for a $10 launch fee, providing access for those wishing to paddle or cruise the lower reaches toward the sea.
