Police are putting in place measures to prepare for anticipated protests around Parliament grounds next week.
The Freedoms and Rights Coalition, which has led recent protests in Auckland and Christchurch, is planning a protest in Wellington on 23 August.
A counter-protest group was also planning to gather near Parliament, police said.
Road closures and parking restrictions will be enforced around Parliament grounds, from 10pm on 21 August to deal with any disruptions.
Police said a traffic management plan, including road closures and parking restrictions, would be enforced from 10pm on 21 August around Parliament grounds to restrict unauthorised vehicle movement and parking until the end of the protests.
The road closures will be in place at the Parliament end of Lambton Quay, lower Molesworth Street, and Kate Sheppard Place.
While commuters and people who work or move through the area were being asked to plan ahead, police said they expected traffic disruption to be minimal.
"We acknowledge it is important that people have the right to peaceful protest.
"However, police will take action against unlawful behaviour.
"Our expectation of these protesters is that their protest will remain lawful at all times."
