The year 1838 showed a further increase to 26 ships. The number of Americans had more than doubled, but that season is notable for the first appearance on the New Zealand coast of large numbers of French whaleships. A single French ship, the "Mississippi", had worked from Cloudy Bay in 1836, but in 1838 she returned as one of a fleet of 16 French whaleships. Among these was the "Cachalot", commanded by Jean Langlois, whose land purchase from the Māori led to the French attempt to establish a Colony at Akaroa in 1840. The number of French ships sharply increased in 1841 and 1842 after the establishment of the French settlement at Akaroa. In the first four months of 1843, there were 17 French, and ten American whaleships out of a total of 26. After 1843, foreign whaleships no longer came to New Zealand due to the enforcement of Customs regulations.
