Formally La Compagnie de Bordeaux et de Nantes pour la Colonisation de l’Île du Sud de la Nouvelle Zélande et ses Dépendances - was a French company inaugurated in 1839 by a group of merchants from the cities of Nantes and Bordeaux, with the purpose of founding a French colony in the South Island of New Zealand.
The company was formed after negotiations in August 1838 between whaling boat captain Jean-François Langlois and several Ngai Tahu Māori chiefs for the purchase of several thousand acres of land on Banks Peninsula, for which Langlois promised to pay a total of 1000 francs. Upon returning to France in 1839, Langlois set about founding a company with the help of several financial backers, the eventual aim of which was to claim the entirety of the South Island for France.
On 30 June 1849 the company's remaining New Zealand properties were bought by the New Zealand Company for the sum of £4,500.
