COMMISSIONER Central Lieutenant Colonel Laisenia Tuitubou says they will know the actual cost of damage to infrastructure by the floods in the Central and Eastern divisions in two to three weeks.
Lt-Col Tuitubou said the estimated figure now stood at about $3million to $4m.
"Maybe it will be more," he said.
"Costing is expected to surpass $5m, $4m on infrastructure alone.
"We anticipate in the next two to three weeks where we can get the actual costs, when everything is accessible. Some of the areas are not accessible by foot, even by vehicle so our team has to walk."
He confirmed 11 evacuation centres in the Central and Eastern divisions were still activated.
"Eight in Naitasiri, two in Rewa and one in Naikorokoro Village," Lt-Col Tuitubou said.
"About 400 to 500 people are still in these centres. We are awaiting clean up by fire officers and spraying by the Health Ministry. They won't move back to their homes until the all-clear is given from the Health Ministry." He confirmed that 70 per cent of the clean-up and spraying had been done.
