The New Zealand Government has pledged a further $2 million for both Fiji and Samoa after Cyclone Evan ripped through the countries.
Torrential rain and gale-force winds have destroyed homes and left a trail of devastation.
The repair bill will top hundreds of millions of dollars.
Foreign Affairs Minister Murray McCully announced on Wednesday that the additional funds had been offered to both countries to assist with the recovery effort.
The Government has already contributed $600,000 to Samoa and $400,000 to Fiji.
A New Zealand Royal Air Force P3 Orion is now in Fiji helping to survey the damage after earlier assisting in Samoa.
Meanwhile, a state of natural disaster has been declared for the western and northern divisions of Fiji - expected to be in place for a fortnight - as the clean-up from Cyclone Evan continues.
Inmates from Natabua prison and 100 local soldiers are helping with the clean-up, The Fiji Times is reporting.
Thousands of people took refuge in evacuation centres, as the cyclone pounded northern parts of Fiji for more than 12 hours on Monday, causing flooding and extensive damage.
Roads were closed and power and water supplies were cut.
No fatalities were reported.
A search for 10 fishermen missing from four fishing boats after the cyclone struck Samoa late last week was called off on Tuesday morning.
Four people were known to have died in the cyclone, and about 5000 people had been displaced in Samoa.
