The Waioeka River runs through a bush-clad valley south of Ōpōtiki in the Bay of Plenty region of New Zealand's North Island. The river offers grade 1 and 2 paddling throughout its length, making it well suited to beginner and intermediate paddlers while still providing an engaging experience for those with more experience.

The full paddling distance is 27 kilometres, with a shorter 11 km section ending at Graham's Bridge. Experienced paddlers can complete the run to Graham's Bridge in 45 to 60 minutes, while the full 27 km typically takes 2 to 3 hours. The full distance is not considered appropriate for families or inexperienced paddlers, and those newer to the sport are advised to paddle only a shorter section.

Access points are located along the roadside, with river access available at multiple spots. Paddlers should expect up to 5 minutes of carrying boats from the road to the water at these entry and exit points. There are no toilets or shops along the river, so paddlers should stock up on supplies in Ōpōtiki before setting out.

The river corridor is characterised by wilderness scenery and bush-clad surroundings throughout its length. Every October, the Waioeka hosts a multisport race in which hundreds of competitors paddle a section of the river, reflecting its reputation as one of New Zealand's well-regarded stretches of river for paddling.

For those interested in more technical whitewater, the Waioeka Gorge section near Whakatāne offers grade 3 conditions when the river level is above 2.2 metres. The Opato, a tributary of the Waioeka, provides grade 4 creeking when the Waioeka flow exceeds 3.0 metres. Flow information for the gorge section is available through an online flow site, with an alternative contact number of 0800 368-288 extension 9258. The marker post for the gorge put-in is located at the Wairere dam.
