The Pororari River flows from Paparoa National Park on New Zealand's West Coast, emptying into the Tasman Sea near the village of Punakaiki. The river passes through a dramatic limestone gorge characterized by towering cliffs, enormous boulders, and deep emerald pools, with sub-tropical nikau palm groves and dense native rainforest lining its banks. The overall character of the paddling experience is calm and exploratory — the river is suitable for families, beginners, and first-time paddlers, particularly in the lower reaches and the Pororari lagoon near the river mouth. More experienced paddlers can venture further upstream toward the lower reaches of Cave Creek.

The primary access point is at the Pororari River bridge, located 1 km north of the Paparoa National Park Visitor Centre on State Highway 6. Parking is available at the car park adjacent to the bridge. Two local operators offer kayak and stand-up paddleboard rentals from this area: Waka Puna Paddle and Pedal Co (formerly Punakaiki Canoes) and Paddle 'N Carve, both of which supply safety equipment including life jackets. Typical hire sessions run between 1.5 and 2.5 hours.

As the river flows through Paparoa National Park, dogs are not permitted. Alcohol, drugs, and illegal substances are prohibited while using rental watercraft. Rental operators reserve the right to refuse hire during adverse weather or river conditions. Heavy rainfall can cause sections of the surrounding track to become impassable, and the area is subject to rockfalls in certain sections of the gorge. Hunters may be present in the lower and upper sections of the river area.

Paddle 'N Carve operates daily from November through April, indicating that the warmer months represent the primary paddling season. Wildlife visible along the river includes kingfishers and other birdlife. Notable features along the route include large rock formations, deep pools with striking water color, and the limestone gorge walls. The river mouth area includes a sandstone rock formation known locally as "the boot." The Pororari lagoon, situated near the river mouth and adjacent to Punakaiki Beach Camp, offers a particularly calm paddling environment.
