UPDATED 5:00pm As the death toll continues to rise in Fiji, New Zealand's committed more aid funding and supplies.

A further $1.8 million is being donated to the recovery effort, bringing our total contribution to just over $2 million.

Foreign Affairs Minister Murray McCully said there'll also be another Defence Force flight to help with the clean up.

"Chainsaws and tarpaulins and that sort of stuff, as well as a joint reconnaissance team that will help with the assessment work."

Getting core services back up and running is the focus for New Zealand aid efforts.

Mr McCully said it's a major recovery operation, and the Fijian authorities need technical assistance for some of it.

"It could include things like getting the electricity supply back up and running, damage to water systems. Engineering skills particularly are a big focus at a time like this."

But it could be days before the full extent of the cyclone damage in Fiji is known.

The official death toll from Cyclone Winston - one of the most powerful cyclones on record - now stands at 10, however that number is expected to rise.

It's had a devastating impact on the islands.

Dozens of centres remain without power and water after the storm packing gusts of up to 325 kilometres an hour hit.

CARE Australia worker Anna Cowley said the impact will be tremendous.

"There are only a few houses still standing in certain villages. This one is the strongest one to hit Fiji for sure."

Unicef spokeswoman Alice Clements said it will take some time to get a clear picture.

She said stories are coming out about relatively established and large towns on the main island of Viti Levu, like Ba and Lautoka.

"Talking about the hospitals being severely damaged and at least one eyewitness was saying there isn't a house that isn't damaged."

Aid agencies are meeting with the Fijian Government and with each other today to coordinate the response.

Oxfam's Pacific regional director Raijeli Nicole said based on experience, safety, shelter, food, protection, water and sanitation will be the priorities.

"They main thing is to ensure all the key bodies that are involved in the response that we are coordinating and we are talking to one another."

Raijeli Nicole said it's very clear the Government is in the leadership role, which makes the work of international NGOs and other players very easy.
