An ocean exploration company's been contracted to resume the search for the Malaysia Airlines flight which vanished in 2014.

Flight MH370 was travelling from Malaysia to Beijing when it disappeared with 238 people on board, including two New Zealanders.

The family members of the people on the missing flight have been sent a note by Malaysian authorities that Texas company Ocean Infinity will resume the search that was called off last year.

It's reported the company will use the Seabed Constructor vessel for the search as the ship carries eight unmanned submarines and can scan 12-hundred kilometres every day.
