A lodge owner and 21 Australian tourists have been evacuated to the Vanuatu capital Port Vila after more attacks on a resort on Tanna.
At least one of the tourists is reported to have been injured after stones were thrown.
The Daily Post reports a fire started in the early hours of Tuesday morning when vehicles were set alight by what appeared to be petrol bombs.
The New Zealander who owns the resort, Hugh Lowe, told the paper staff fought the fire until 5.30am and managed to save some of the buildings.
The first six houses were burnt last month and were reported to be in retaliation for the alleged murder of a young Tannese boy.
Vanuatu's Deputy Prime Minister and Minister of Tourism, Moana Carcasses, says he won't tolerate people taking the law into their own hands.
He says Australia is Vanuatu's biggest tourist market and the Government won't stand by while Australian tourists are harassed.
He says he may send members of the Vanuatu Mobile Force to Tanna to arrest the perpetrators.
The Island's Nikoletan Council of Chiefs are reported to be holding urgent meetings to find a way out of the issue.
