The company started last year and had been selling fish to locals, exporting fresh and frozen tuna.
The Director General for Fisheries, Moses Amos, said the government had decided to inject over $US873,000 into the joint venture to push the production of canned tuna.
The financing is part of a multi-million dollar package allocated to the productive sector.
Amos said the production of canned tuna is a step forward for Vanuatu in preparations towards disasters.
He said the factory should be able to produce over 2200 cans of tuna a day, using one ton of fish.
