Duvauchelle Bay (Māori: Kaitouna) is a small town situated at the head of Akaroa Harbour on Banks Peninsula in New Zealand.

The site of an ancient Māori pā or fortified settlement is at Oinako, where the Duvauchelle Hotel stands today.

[3] The name of the town and bay comes from the surname of two brothers Jules-Augustin and Louis-Benjamin Duvauchelle, who held land there from the Nanto-Bordelaise Company, at the time of the French settlement at Akaroa in the 1840s.

The first freeholds were bought in 1857; economic activity was focused on timber extraction and sawing, mostly tōtara trees.

[4] The first settler at the Head of the Bay, the location of the present town, was a Frenchman called Libeau, who arrived in 1841.

A small building that served as both church and school was built by local people on a half-acre plot of land donated by Lord Lyttelton.

It is grouped with other settlements including French Farm, Wainui, Robinson's Bay and Takamatua as the statistical area of Akaroa Harbour.
