The Ōtākaro/Avon River flows through the heart of Christchurch on New Zealand's South Island, running past the Botanic Gardens, through the city centre, past Margaret Mahy Playground and Kerrs Reach, and out to the Ihutai estuary. The river is spring-fed, which historically made it a significant mahinga kai (traditional food source) for Ngāi Tūāhuriri Māori, and it carries considerable cultural and historical importance as a place where early Māori and European settlers interacted in building the city of Ōtautahi Christchurch.

The primary access point for independent paddlers is the Antigua Boat Sheds, a historic facility over 130 years old, where single and double kayaks, pedal boats, and Canadian canoes are available for hire year-round. Another entry point noted by paddlers is near 127 Rossall Street, which provides access to a stretch passing private Fendalton gardens before continuing through the city. Waka experiences depart from 794 Colombo Street opposite Victoria Square and from Margaret Mahy Playground.

The river offers a calm, flat-water experience well suited to beginners and those seeking a relaxed paddle. The stretch through the Botanic Gardens is particularly pleasant, with river wildlife visible along the way. The character of the paddle is generally unhurried, passing through urban parkland and gardens rather than wilderness.

For those interested in guided cultural experiences, Waka on Avon operates 45-minute and 75-minute guided waka paddles led by local Ngāi Tūāhuriri guides. These experiences include a traditional mihi whakatau (welcome), instruction in paddling technique, and storytelling about the river's cultural history. Pricing for the 45-minute Kaitiaki experience is $79 for adults and $45 for children aged 5–15. The 75-minute Manaaki experience is $99 for adults and $55 for children.

Punting is also available from the Antigua Boat Sheds through the Botanic Gardens year-round, and from Worcester Bridge through the central city precinct in summer, which may affect river traffic in those areas. The river is accessible for independent paddling on personal watercraft, as confirmed by accounts of paddlers using their own kayaks on the river.
