Jennings said police will be monitoring the movement of protest groups travelling to Wellington.
Separately, Farmers’ protest group Groundswell NZ have organised a Drive 4 Change event and will be travelling north on State Highway 1 from Timaru to Christchurch on Sunday as part of their drive to all the way to Auckland. A spokesperson said the protest is not one of the groups heading to Parliament and will be bypassing Wellington city.
“Poor weather is expected across Canterbury over the coming days, and motorists should travel to the conditions,” Jennings said.
“There is expected to be additional congestion, so police advise Canterbury motorists to anticipate delays on their travel or take alternative routes where possible.”
Motorists in Christchurch should expect heavier traffic around Tower Junction on Sunday afternoon as the convoy arrives.
It will continue north on State Highway 1 to Kaikōura on Monday morning.
Any unlawful activity or disruption on the road network should be reported to police, Jennings said.
More details on road closures in Wellington will be provided early next week.
Police have warned parking will be restricted, so anyone travelling into the city should make alternative arrangements or use public transport where possible.
“While there will be some disruptions, our aim is to ensure residents and the wider public can continue to go about their daily business as uninterrupted as possible,” Jennings said.
