Pacific island nations seem to have avoided any major damage from the surging waves created by Japan's earthquake.
Oxfam Australia says minor property damage has been reported in Papua New Guinea, where the Boram Hospital in Wewak was flooded by waves.
About 50 of the hospital's 100 patients were evacuated to a police station where most are lying outside.
Oxfam says it is providing tarpaulins, food and water to patients.
In Bougainville, 20 people from the coastal village of Kobuan were evacuated after their homes were pounded by waves.
But in the neighbouring Indonesian province of Papua, a man is said to have been killed in a coastal village near the town of Jayapura.
Waves swamped the village destroying six homes and 10 hectare fish ponds.
In the Solomon Islands, water reportedly reached 50 metres inland, destroying at least one home and washing canoes away.
