The Wairoa River, also known as Wairoa South, is the second longest river in the Auckland Region of New Zealand's North Island. It flows south from its sources in the Hunua Ranges, then northwards into the Hauraki Gulf. The Wairoa Reservoir and Hūnua Falls form sections of the river, and the Wairoa River flows adjacent to the township of Clevedon.
