Door-to-door salespeople who ignore a home's "do not knock" sticker will be risking a fine of up to $10,000 under new rules.
And the business they work for could be stung up to $30,000.
The Government says it is tightening the rules on uninvited door-to-door vendors. From 2020, they will have to leave immediately if told to, including by a sticker or other written notice, or risk being taken to court by the Commerce Commission under the Fair Trading Act.
Chiefs of door-to-door businesses that sell on deferred payment terms would have to be listed on a public register and pass a "fit and proper person" test, said Commerce and Consumer Affairs Minister Kris Faafoi.
The changes were announced today with the legal crackdown on loan sharks.
