Paul, the owner Endeavours Kindergarten in Flagstaff, was remanded at large without plea to seek legal advice.
She will reappear in court in January.
The gridlock saw the coalition protesters - including cars, van, trucks and motorbikes - begin their 23km journey north of Hamilton near Horotiu at 11am before travelling south to Waikato Hospital and back north to Te Rapa.
Meanwhile, the 36-year-old woman, from Rototuna North, accused of riding on the car is facing two charges - riding on a vehicle on a road in a position which may have been liable to cause injury to the rider and breaching Covid alert level 3 conditions by leaving home for a purpose other than for essential personal movement.
The charges have a maximum penalty of $1000 fine.
She is due to appear in the Hamilton District Court in January.
