The full Māori name of the river is 'Te Wairoa Hōpūpū Hōnengenenge Mātangi Rau', which means the long water which bubbles, swirls and is uneven. This refers to its turbulence and hidden currents. Ruakituri, Hangaroa, Mangapoike, Mangaaruhe and Waiau Rivers are all tributaries of the Wairoa River.
The river is best enjoyed from the Wairoa River Walkway, which winds along the banks of the river from the historic lighthouse in the CBD, finishing at the famous lookout point on Pilot's Hill. In the few years since the walkway was started, it has become a mainstay in the recreational activities of both residents and visitors alike. On any day of the week, people can be seen enjoying the path, whether it be taking a leisurely stroll, running or cycling with the family.
