Truckies are heading into Auckland city's CBD in convoy to protest against high petrol prices.
As many as 50 trucks have so far joined trucking company RNB Transport's protest, recently driving bumper-to-bumper past the Constellation Drive on-ramp along the Northern Motorway.
The empty haulage trucks are creeping along in the slow lane with lights flashing and some tooting their horns after the first protesters left Silverdale, north of the city, at 7am.
Organiser Rob Ryan said the truckies want to keep disruption to a minimum, but they're running out of options to get their voices heard.
"All we're trying to get noticed - that's all we're trying to do.
