WELLINGTON, New Zealand -- The death toll from a ferocious cyclone that tore through Fiji has risen to three as authorities continue to assess the extent of the damage to the Pacific Island chain.

George Dregaso from Fiji's National Disaster Management Office says two people on Ovalau Island died when the house they were sheltering in collapsed on them. Another man died on Koro Island, although it wasn't clear how. Police are investigating reports of two more deaths on the main island of Viti Levu.

Cyclone Winston hit Fiji Saturday with wind speeds of up to 285 kilometres (177 miles) per hour, destroying hundreds of homes and shredding crops.

A curfew has been extended through Sunday and police empowered to make arrests without a warrant.
