Under the label Brasserie de Wallis and Futuna the micro-brewery plans to produce 250,000 bottles a year, local television says.
The project was launched by New Caledonian businessman Pierrick Maury, who has already opened a brewery in New Caledonia.
Mr Maury said he was still seeking investors in order to have as broad an ownership as possible, selling minimum stakes of $US100.
Once operational, the plant is expected to have nine employees.
Annual beer consumption in the territory is more than one million bottles a year.
