Today consumer researcher Jessica Wilson told Newstalk ZB's Mike Hosking it was time the Government banned clamping.
Property owners can legally clamp and charge as much as they like so long as the area is clearly posted as a private car park.
"These guys can buy a few clamps and set up shop. They're effectively holding consumers to ransom. We wouldn't expect to see this on council-owned properties - you park on the street or in a council-owned building - you don't get your car clamped but for some reason we're allowing private parking operators to get away with this."
Wilson said it was an archaic practice and time it was gone.
"Get rid of clamping. It's an egregious situation. These guys are effectively holding consumers to ransom," she said.
