Duvauchelle Bay (Māori: Kaitouna) is a small town situated at the head of Akaroa Harbour on Banks Peninsula in New Zealand. State Highway 75 passes through the town. The Onawe Peninsula separates Duvauchelle bay from Barry's Bay. Duvauchelle is now part of Christchurch City Council jurisdiction since the city's amalgamation with Banks Peninsula District in 2006. From 1910 until 1989, Duvauchelle was the seat of the Akaroa County Council.
