Relief efforts are to be stepped up in Tonga today to help the thousands of people affected by Cyclone Ian, which caused extensive damage.
One person was killed in the Ha'apai islands when winds exceeding 280 kilometres an hour tore through on Saturday.
Most homes in the northern region have been either damaged or destroyed, including one village with about 40 homes on tiny Mo'unga'one Island were completely flattened, local media report.
Communication is difficult and power has been cut.
A spokesperson for the Tonga Power company, Seti Chen, says the damage is extensive.
"We are probably looking at about 90 percent of the lines, if not 100 percent of the lines, that are down. We have quite a few damaged transformers as well. All in all the damage on the actual network is quite extensive."
The New Zealand High Commissioner to Tonga, Mark Talbot, says New Zealand stands ready to help in the relief effort for the worst cyclone-hit areas.
"There may be some areas they may approach some of their friends in the region, including New Zealand. There are a whole of variety of things that New Zealand could offer by way of support. This is something the government of Tonga will reach its own decision on."
Mark Talbot says the New Zealand Government is contributing 50,000 dollars in initial aid.
