Auckland commuters are facing delays on Sunday with farmers lobby group Groundswell bringing traffic to a halt on the Southern Motorway.
A police spokesperson told Newshub the protest group planned to meet at Great South Road in Ramarama at 9am before travelling to Ellerslie on Auckland's State Highway 1 Southern Motorway.
Waka Kotahi New Zealand Transport Agency (NZTA) said the convoy was causing delays between Drury and Takanini shortly after 11am but congestion has since eased.
At 11:30am, Google Maps showed a red line of traffic from Rainbows End near SH1 to near Ōtāhuhu.
Auckland Transport (AT) said it's aware of the protest and warned Aucklanders it could affect traffic.
"Auckland Transport is aware of an event involving slow-moving traffic on Sunday, that will likely cause disruption to transport across the Auckland roading network from 10am until 3pm," AT said in a statement.
"A convoy is expected to travel north on SH1 from the Ramarama on-ramp, exiting the motorway at the Onewa off-ramp across the Harbour Bridge."
AT said the protest group would then re-enter the motorway at the Onewa on-ramp southbound and then travel through the Auckland CBD to Ellerslie Racecourse.
"Please use the journey planner to plan your public transport journey in advance and expect delays in the surrounding areas," AT said.
The protest group is expected to gather at the Ellerslie Racecourse at 12:30pm on Sunday.
The protest is part of a 10-day trip starting in Invercargill on September 22 and going all the way up to Auckland on Sunday.
The farmers are protesting what they describe as "unworkable" regulations imposed on farmers through Labour's climate policies.
