More than 1700 Fijians have sought refuge in 46 evacuation centres and another 1800 are in tents, as bad weather batters the island nation.
Heavy rain and floods have cut access to roads, including the main road joining the capital, Suva, with Fiji's international airport at Nadi.
There have so far been no reports of death or serious injury.
Fiji Broadcasting Corporation journalist Maggie Boyle told Newshub the bad weather was particularly drastic, even for cyclone season.
"The main Rewa river burst its banks not once but twice over the last couple of days, flooding the entire Rewa delta, leading to a number of communities and villages being cut off from the main access roads and a number of houses taking in up to 1.6m of water."
Ms Boyle says initial cost estimates from the Water Authority of Fiji put repairs at about $1.8 million (NZ$682,000).
The Water Authority has issued a warning to boil all drinking water before consumption, and says some areas might get water cuts from burst mains or clogged intakes.
Fiji police say they are continuing to work as best they can despite the Ra police station being flooded.
