San Francisco Frontiers - New Zealand protesters burn camp after riot police move in

Police abandoned their light-touch approach, with hundreds of officers using perspex shields, pepper spray and water jets to force back protesters, who responded by hurling bottles, bricks and paint bombs.

When it became clear police were winning control of the makeshift tent city that sprang up on parliament's lawns three weeks ago, the demonstrators torched it themselves.

"This is not over," one man yelled, while others chanted "Shame on you" at advancing officers as a thick pall of black smoke enveloped the area.

Police deployed an ear-splitting sonic cannon and high-pressure water hoses to help disperse the crowd, although a few dozen regrouped and fought running battles with police on nearby streets into the evening.

Prime Minister Jacinda Ardern backed the force's tough tactics, angrily denouncing the violence as a "desecration" of parliament's grounds.

"It was an attack on our frontline police, it was an attack on our parliament, it was an attack on our values, and it was wrong," she told reporters in parliament as rioting continued a few hundred metres (yards) away.

She said what began as a movement against coronavirus vaccine mandates -- inspired by similar protests in Canada -- had turned toxic and the demonstrators' conduct was "disgraceful".

Ardern said the protesters represented a small group whose extremism was fuelled by conspiracy theories and misinformation.

"We have a difficult journey in front of us, to address the underlying cause of what we have seen here today -- but in doing so, we will never, ever excuse it," she said.

- 'It needs to end' -

Police launched a pre-dawn push to clear roads around the legislature, using a large forklift truck to remove cars and campervans that arrived in the capital in a convoy on February 8 and were used to jam downtown streets.

In the afternoon, they turned to the protest's epicentre on the lawns of parliament, where around 3,000 people congregated at the height of the demonstration about two weeks ago.

Numbers have since dwindled to a hard core of about 300 who police commissioner Andrew Coster said had shown a willingness to use violence not shared by legitimate demonstrators.

"We've seen tactics (from protesters) today including spraying fire extinguishers at the police line, the throwing of paint, early on we saw weapons," he said.

He said police were not seeking confrontation but added: "This protest has now tipped over a balance and it now needs to end."

At least three officers were hospitalised with "non-life threatening" injuries in the operation to clear the parliamentary precinct, which left a few dozen angry protesters milling on nearby streets hurling stones.

The show of force came after vocal criticism from Wellington locals about the hands-off approach previously adopted towards the demonstrators.

Residents have complained about being abused by anti-vax activists for wearing masks, while schools and businesses close to the camp have closed for safety reasons.

In recent weeks, police have accused protesters of hurling human faeces at them, spraying a "stinging substance" at officers and slashing tyres on police cars.

Coster said Wednesday's operation came after efforts to "de-escalate" the situation and end the protest peacefully had stalled.

"We reached the stage where protest leaders were unwilling or unable to effect meaningful change," he said.
