The wheel-clamping law change came after several businesses indiscriminately clamped motorists and charged hundreds of dollars.
Motorists complained that they had only stopped for a few minutes or were unaware parking was not permitted because of unclear or ambiguous signage.
One of the
most notorious examples
was a West Auckland retail complex where a company called Elite Parking Services clamped shoppers' cars and demanded as much as $450 to get their car released.
In many cases, the shoppers had only been parked for a few minutes in what appeared to be a 120-minute parking zone.
Another business, Bamford Antiques in Ponsonby, gained a reputation for aggressively clamping motorists, in one case charging a couple $760 to get their car released.
The AA and Consumer NZ said that if the new law change failed to deter rogue clampers, a ban on clamping should be introduced.
An outright ban was considered but rejected by government officials during development of last year's law change, because they did not see it as a widespread problem.
The crackdown on wheel clampers was based on anecdote rather than hard evidence of a significant problems, officials at the Ministry of Business, Innovation and Employment said.
