Aucklanders are advised of possible delays on part of the motorway network and roads near the central city, on Saturday, due to protest activity.
A large-scale Police operation will be running to prevent any unpermitted pedestrian access to the Auckland Harbour Bridge or motorway network.
The Freedom and Rights Coalition's permit to march on the bridge was declined in December by New Zealand Transport Agency Waka Kotahi.
Police have clearly advised the group that it will not facilitate access for the group.
Superintendent Naila Hassan, Waitematā District Commander, says Police will be well placed to respond to unlawful attempts to access the bridge on foot.
"A large operation has been planned, with resource coming from across the Auckland region and other parts of the country," she says.
"Our focus will be on ensuring everyone's safety and to minimise any disruptions to those Aucklanders going about their business as much possible.
"If you are accessing the motorway network near Victoria Park, or city centre and Ponsonby, please prepare ahead for delays and significant bus detours."
Superintendent Hassan says there is no permit to access the motorway network on foot, and anyone attempting to do this will be acting unlawfully.
"Anyone attempting this will be subject to enforcement action, and we strongly urge anyone considering taking part to think about their actions.
"Police reiterate that the public have the right to protest, provided that it is peaceful and lawful."
Police and NZTA jointly issued a statement of record earlier this month, outlining the risks to personal safety and infrastructure.
Police will continue to keep the public advised of any disruptions that arise through Saturday.
"We appreciate the public's understanding in this matter."
A second protest event in central Auckland, on Queen Street between Te Komititanga Square and Myers Park, is also expected to cause delays in the area on Saturday afternoon.
