The Governor General of Solomon Islands has declared a nightly curfew in the troubled capital Honiara, after a third day of looting and destuction.
Sir David Vunagi says the curfew, which starts tonight, will go from 7pm to 6am and be repeated every day until it is revoked.
Sir David says it is a necessary measure for the preservation of public security.
Only authorised officers are allowed to move within the city during curfew hours and anyone found breaching the restrictions will be prosecuted.
Rioting has been continuing in Honiara today, with reports protesters had set a building on fire behind the Prime Minister's residence.
A protest on Wednesday calling for the prime minister Manasseh Sogavare to stand down has lapsed into major unrest which local police have been unable to contain.
Dozens of Australian police have arrived in Honiara to help local forces. More forces including Australian Defence Force personnel are due to arrive later today [Saturday].
Papua New Guinea security force personnel have also touched down in Honiara to support local police.
PNG's Police Commissioner David Manning is leading the PNG security contingent of 35 police and corrections officers.
An Australian Navy vessel is also enroute to Solomon Islands.
Tension is high in front of Sogavare's residence where more than a hundred protestors have been throwing rocks while police with riot shieds fire tear gas.
Australia's Federal police officers are also visible in front of the Prime Minister's residence.
RNZ Pacific correspondent Elizabeth Osifelo reported earlier that there are checkpoints set up around the city where the eastern part has been in flames.
"There's a lot of tension still and especially a few metres around the prime minister's residence. There's a group of protesters and people around there.
"The police are still trying to push people back and there's been tear gas fired," she said.
There is no confirmation where Prime Minister Sogavare is at this time.
Elizabeth Osifelo add that households in the capital are facing likely food shortages after looting during the ongoing unrest.
She said the destruction is focused on the city's east where many businesses have gone up in flames or been emptied.
"But as of yesterday, a lot of these little canteens that are located in the residential areas have also gone out of stock so a lot of families will definitely be affected if this holds up for another day or two.
Meanwhile, the opposition leader, Matthew Wale, is reiterating his call for the prime minister to stand down.
Wale said the basis for the unrest is a political problem, so it requires a political solution.
He categorically denies accusations that he has played a part in inciting the unrest, and is calling for MPs in the government to leave Sogavare's coalition
"MPs should listen to what the people are saying and not allow more destruction. The violence, of course I don't condone it. But at the same time, leaders have decisions to make," he said.
The prime minister has said that he was elected on the floor of parliamant and can only be removed on the floor of parliament.
But Wale said that the country's democratic processes were paralysed by the control of numbers in parliament.
He said the Sogavare government's move to switch diplomatic ties from Taiwan to China in 2019 has played a part.
"Sogavare controls those numbers because he attracts a lot of funding from loggers and - now it's very clear - from China. So China is interferring in our domestic politics. It's very, very clear."
According to Wale, people are angry because the country's system of government has become capitive to vested interests of logging and mining companies, as well as China.
"And so the interests of the people are sidelined or totally ignored and neglected, and that's why they feel they have to take it up themselves.
"It's a really tragic situation, it's an unfortunate situation that people lose trust in the democratic processes."
Wale said the national government's persistent persecution of Malaita province has brought things to a head.
New Zealand response
New Zealand's acting Foreign Minister, David Parker, said Aotearoa New Zealand is deeply concerned at the events unfolding in Solomon Islands.
He said New Zealand is a long-standing partner of the Solomons, and there are deep and enduring connections between the two countries.
Mr Parker said New Zealand's engagement in the Solomons is guided by the principle of tātou tātou - everyone acting together for the common good.
He said New Zealand stands with the government and people of Solomon Islands.
Mr Parker said New Zealand will remain in close contact with its Solomons counterparts and international partners, though there has not yet been a request for assistance.
New Zealand Police are currently providing advice and support to their counterparts in the Solomons.
The High Commission in Honiara is providing SafeTravel advice to New Zealanders in the country.
Only six buildings still standing in Honiara's Chinatown
RNZ Pacific correspondent in Honiara, Georgina Kekea, said there are only six buildings still standing in Honiara's Chinatown after two days of rioting.
She said there are also unconfirmed reports that one or more of the looters were trapped in burning buildings and lost their lives.
Ms Kekea said there is no longer an air of tension but scavenging is continuing, though there is little left for people to steal from the destroyed businesses.
"Only six of the buildings were OK because they had locals minding the buildings, otherwise most of the buildings in Chinatown have been burnt down, scavengers now coming in and getting whatever they can and going back to their homes with it. There is nothing much left from the buildings anyway."
Georgina Kekea said the police's focus is entirely on ensuring there is no more rioting, so looters are being ignored.
She said some buildings are still on fire.
