Houhora Heads campground proprietor Cathy Wagener has appealed to the Far North District Council to paint arrows on the road to remind foreign drivers to keep left.
"These tourists, a lovely couple from Chile, had arrived the night before, having found the accommodation they had booked elsewhere closed," she said.
"On the morning of the accident, they went to the office and asked to book another night.
"They said they had fallen in love with the camp and wanted to stay on.
"They headed out the drive, and within a couple of hundred metres were involved in this dreadful accident."
Earlier the same morning in an unrelated incident, a campervan had been driven on the wrong side of the same road. A local woman who was following tooted and signalled until the driver realised their mistake and corrected.
"There have been a number of near misses on other occasions, and this is an ongoing problem," Wagener said.
"We have decided to put up a notice at the gate asap, reminding visitors to drive on the left.
"Would it be possible for the council to paint arrows on the road outside the camp as a further reminder to tourists to keep left?
"Perhaps this way another such tragedy could be avoided."
Mayor John Carter said he would ask council staff to address the issue, as they had been asked to do on West Coast Road in Waipapakauri and other tourist roads.
