Extended warranties are being sold with misleading advice and shoppers are not told they already have similar protection under the law, a survey has found.
The warranties can cost hundreds of dollars and are sold as a "peace of mind" way to extend the 12-month manufacturer's warranties that come with a wide range of electronic goods.
But Consumer NZ say such deals are not generally needed because if a product breaks down after the manufacturer's warranty then consumers are still protected by the Consumer Guarantees Act (CGA).
Consumer NZ chief executive Sue Chetwin told the Herald that information given to shoppers about the need for extended warranties was so wrong it was deliberately misleading.
"There really is no excuse for the staff on the floor not understanding the Consumer Guarantees Act. So you would have to argue that this really comes from the top."
