The group plans to travel about 25km/h and the route includes: Paengaroa along the expressway, Hewletts Rd, Tauranga Harbour Bridge, and will end at the Sulphur Marine Car Park.
Police say they are aware of planned protest activity across the country on Saturday and will monitor activity.
"Police officers will maintain a presence and will respond to events as appropriate at the time," a police spokesperson said.
"As with previous large gatherings, police may follow up on any identified offences or breaches at a later time."
A Waka Kotahi spokesperson said traffic operations centres would be closely monitoring highways and supporting police today.
"Police's district teams will be responsible for managing traffic and crowds.
"Waka Kotahi will provide real-time messaging on traffic volumes and any delays or disruptions as needed, via our regular channels including Twitter and Facebook. State highway traffic information is continuously updated at: journeys.nzta.govt.nz/traffic," the spokesperson said.
The protest group is associated with Destiny Church, whose leader Brian Tamaki has been charged by police with breaching the Health Act for organising a series of protests at Auckland Domain.
