The Waingaro River is located in the Golden Bay region of New Zealand and is regarded as a classic destination for advanced packrafters. The river features a demanding grade IV gorge section followed by sustained grade III whitewater that continues all the way to the takeout, making it a technically challenging run suited to experienced paddlers.

Access to the put-in involves a 7-hour hike along the Kill Devil track, which involves significant elevation gain before descending into bush near the river. A DOC hut is available near the put-in, providing an overnight option for those arriving the day before paddling. The approach hike is considered worthwhile in its own right, offering extensive views before dropping into the forested valley. The full trip is best planned as a two-day adventure.

Water levels are an important consideration — optimal flows are necessary to get the most out of the run, and paddlers should time their trip accordingly. The river's character can be deceptive: at least one party found that significant whitewater continued well beyond the grade IV gorge, with challenging grade III rapids persisting for additional hours of paddling. Paddlers should not assume the technical difficulty eases after the gorge section.

Safety preparedness is essential on this remote river. Carrying a Personal Locator Beacon is strongly recommended, as the logistics of a rescue in this backcountry setting are complex. One documented incident involved a paddler completing the trip with an injury rather than activating a PLB, a decision later described as regrettable — underscoring the importance of being willing to call for help when genuinely needed.

The river runs through attractive native bush, and the overall environment is remote and wild. The combination of the multi-day hike-in, technical whitewater, and backcountry setting makes this a committing undertaking that rewards thorough preparation.
