An earthquake with a magnitude measuring six has been recorded on the Papua New Guinea island of New Britain.

There are no immediate reports of damage from the affected region and the United States Geological Survey office says it is unlikely to have caused a tsunami.

The quake struck at a depth of 43-kilometres under the coast near the district centre of Pomio in East New Britain.

The district is about 700 kilometres north-west of the site where a huge earthquake shook Solomon Islands on April 2.

The quake triggered a tsunami that killed 52 people and left thousands homeless.
