Extra police were called to assist security as protesters tried to move up the steps of Parliament during a protest against the TPP trade deal.
Protesters had pushed through barriers at the front of Parliament in an attempt to move up onto the steps, says Inspector Chris Bensemann, Wellington Police Area Commander.
Police were called to help parliamentary security staff and "were able to contain a small determined group" of protesters to the bottom of the steps, he says.
"These protests have been mainly peaceful in the past but on this occasion a small group tried to move up the steps of Parliament before being stopped by police and security," Inspector Bensemann says.
The protesters eventually moved on and no arrests were made.
The protest was one of numerous demonstrations held in towns around New Zealand today against the proposed Trans-Pacific Partnership free trade deal.
In Auckland thousands of protestors turned out in the rain to march from Aotea Square down Queen Street.
Further south in Christchurch thousands of people turned out in the wet at Hagley Park to march up Riccarton Road, medical students, teachers and marketing executives among the crowd.
In Otago a large group of protesters marched through Dunedin's CBD.
Protests today end an action week by those opposed to the proposed deal.
Rallies were also planned in Wellington, Kataia, Hokianga, Whangarei, Hamilton, Colville, Tauranga, Whakatane, Napier, New Plymouth, Featherston, Nelson, Timaru, Little River and Invercargill.
In Nelson, some of the protesters formed a choir to sing their message.
The US Consulate General in Auckland had warned US citizens to stay away from a march from Aotea Square down Queen Street to Commerce Street. The consulate is in Customs Street East.
"We urge citizens to avoid the protest march route as even demonstrations intended to be peaceful can turn confrontational. We remind citizens to always exercise caution when in the vicinity of any large gatherings, protests, or demonstrations."
Bryan Bruce, a documentary film-maker and investigative journalist, along with New Zealand Council of Trade Unions secretary Sam Huggard were among those scheduled to speak at the Wellington protest.
