The Avon River, known in te reo Māori as the Ōtākaro, is a distinctive urban fishery flowing through the heart of Christchurch in Canterbury, New Zealand. Unlike most productive trout waters, this river winds through one of New Zealand's largest cities, passing alongside Hagley Park and through busy inner-city corridors before continuing through residential and parkland areas. Despite its urban setting, the river holds a surprising population of fish, making it a genuinely unique angling destination — one where you might find yourself casting a fly within sight of city traffic and pedestrians. The Avon/Ōtākaro is not a river that typically appears on lists of famous New Zealand trout waters, yet careful observation of its waters reveals fish holding in spots that most passers-by would never suspect.
