The Office has confirmed that three people, including a three year old, died earlier this week after attempting to make the return crossing to the Ovalau mainland from Moturiki.
It also says four people are missing after leaving to go fishing three days ago off Rakiraki on the island of Viti Levu.
The NDMO says the incidents were associated with a weather system NOT connected to Cyclone Ula, which is passing through the Lau islands in the country's southeast.
