For this reason, many of the area's rivers cascade over waterfalls as they approach the ocean (notably the iconic Purakaunui Falls on the short Purakaunui River).
Oleh karena itu, banyak sungai-sungai di area tersebut mengalir melalui air terjun saat mendekati lautan (terutama Air Terjun Purakaunui yang ikonik di Sungai Purakaunui yang pendek).
