The Ministry of Foreign Affairs and Trade has confirmed two deaths so far following the volcanic eruption and tsunami in Tonga on Saturday.

The Hunga Tonga-Hunga Ha'apai volcano, which erupted on Saturday, was about 65km north of Tonga's capital Nuku'alofa.

There is now a huge clean-up operation in the town, which has been blanketed in thick volcanic dust.

Serious damage has been reported from the west coast of Tongatapu and a state of emergency has been declared.

The Ministry of Foreign Affairs and Trade has confirmed two deaths so far, but Fiji-based United Nations co-ordinator Jonathan Veitch says there were still areas that had not been contacted.

The New Zealand Defence Force has today released images taken during a Royal New Zealand Air Force P-3K2 Orion reconnaissance flight on Monday over Tonga.

The flight was to assist in an initial impact assessment of Saturday's eruption.

Aid is currently being set to the island.
