A campervan that caught on fire while it was being driven along a highway in Tasman has since been extinguished, authorities say.
A witness says the driver noticed the engine was on fire as they were driving along the Coastal Highway (SH60), in Upper Moutere, just before 1:30pm on Friday.
They pulled over quickly at the intersection with Westdale Rd after noticing thick, black smoke pouring out of the bonnet.
