Over 800 people evacuated from the volcanic island of Manam are facing food shortages on Papua New Guinea's mainland.
The islanders were evacuated after the eruption alert level for the Manam volcano was raised to stage three in late April.
According to the newspaper The National, the islanders have been at the Potsdam Care Centre in Madang for almost a month.
Manam leader Paul Maburau said the Madang provincial disaster office gave each family a bail of rice, 5kg of flour and two litres of oil when they first arrived.
He said they had now run out of food and couldn't find any way of obtaining more.
Mr Maburau said people at the care centre were also getting sick and the nearest health centre did not have any medical supplies.
Citing a lack of communication with the Madang government, he said the islanders were confused about whether they would be going back to the island or not.
Mr Maburau said he got two 200-litre containers of petrol from the provincial disaster office and used one to get food from the island on a dinghy but said that was not enough.
Some people, he explained, were starting to leave the care centre and return to the island because of food shortages and other problems.
Mr Maburau appealed to the government to provide a piece of land for them to do their own gardening.
