The Purakaunui Falls are a cascading three-tiered waterfall on the Purakaunui River, in The Catlins of the southern South Island of New Zealand. As one of very few South Island waterfalls away from the alpine region, it has long been a popular destination and photographic subject.
The falls are an iconic image for The Catlins region, and were featured on a New Zealand postage stamp in 1976.
