Kiwis heading to Vanuatu are being warned as the islands of Ambae and Maewo have been evacuated due to the eruption of the Manaro Voui volcano.
Local authorities have raised the volcanic alert level to three out of a possible five.
New Zealanders in or on their way to Vanuatu have been told to follow all instructions of local authorities and to evacuate if asked.
With the potential threat of volcanic ash affecting flights to Vanuatu from New Zealand, travellers have also been advised to confirm their flights are going ahead by contacting their airline or travel agent.
If travel is disrupted due to the volcanic eruption, the advice is to keep all receipts in relation to the trip in case you need to make a travel insurance claim.
