Duvauchelle (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.
Statistics: New Zealand groups Duvauchelle in with other settlements fringing Akaroa Harbour, including French Farm, Wainui, Robinson's Bay and Takamatua. Together, they had a population of 735 at the 2006 census.
The site of an ancient Māori pā or fortified settlement is at Oinako, where the Duvauchelle Hotel stands today. At Te Wharau creek, a taua or war party of Ngāti Awa warriors camped during the battles led by Te Rauparaha in 1831.
The name of the town and bay comes from the surname of two brothers, who held land there from the Nanto-Bordelaise Company, at the time of the French settlement at Akaroa in the 1840s. It is thought that the brothers never lived there. In the following decade, land alongside Duvauchelle Bay was leased from the Canterbury Association by British settlers, including William Augustus Gordon, who was the brother of Charles George Gordon, the famous soldier and colonial administrator, known as "Gordon of Khartoum" after his death. The first freeholds were bought in 1857; economic activity was focussed on timber extraction and sawing, mostly totara trees. Domestic pigs were grazed in the forest, who mingled with the feral pigs that were already present. As the tree cover was cleared, it was replaced with pasture. The first settler at the Head of the Bay, the location of the present town, was a Frenchman called Libeau, who arrived in 1841. Timber exploitation was also the main activity, as well as boat building. The sawn timber was all carried out of the bay by locally built vessels. A public house and a shop were built in the 1850s. 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. The first permanent roads began to be constructed in the 1860s and 1879 saw the arrival of the County Council offices and the Post Office.
Both the Duvauchelle pub and the post office were both badly damaged by the earthquakes that struck the region in 2010 and 2011. The oldest parts of the pub were demolished after the earthquakes. The pub has not re-opened. The Post Office was demolished in late 2012.
