Authorities say the latest downpours have caused severe setbacks to rehabilitation efforts.
The flash floods have been caused by heavy rain from the convergence of two low pressure groups over Fiji.
More rain is forecast over the next two days.
Western Division officials say assessments after last week's floods showed four-point-five million dollars was needed to repair heavy damage to sewerage and drainage systems and roads and bridges.
