The Waiongana Stream is located in the Taranaki region of New Zealand's North Island, situated on SH3 midway between Bell Block and Waitara. It is recognized as a paddleable river, appearing on lists of Taranaki whitewater runs alongside rivers such as the Manganui and Waitara.

Access to the stream is possible from several road bridges, including Devon Road (SH3), Te Arei Road West (off Ninia Road), and Manutahi Road. The lower Waiongana can be reached by turning off SH3 onto Tate Road and then left into Brown Road. Paddlers should be aware that formal public access is limited along much of the stream, and landowner permission is generally required at most access points. A short stretch of esplanade reserve exists along the Waiongana at Brown Road, which represents one of the few points of confirmed public access.

Given the access constraints, it is advisable to contact local landowners or relevant authorities before planning a trip to confirm where put-in and take-out points are legally accessible.
