They were believed to be Swedish tourists who had not been in the country long.
"We took the keys off them and told them we would not be giving them back until the police arrived. I called the police and when they arrived we gave them statements."
One of the police officers told the tourists that if police received another complaint about their driving they would lose their vehicle.
"I really do think tourists coming into New Zealand need to take some kind of driving test before they are let loose on our roads," the eyewitness said.
"It was pretty scary watching the whole thing unfold."
Greymouth police reported this morning that a tourist had received an infringement notice for completing a U-turn in an illegal place in Tainui St.
However, the eyewitness disputed that: "No way was the driver was doing a U-turn - she was definitely driving up Tainui St on the incorrect side of the road".
