Two brands of sunscreen are being recalled following tests that revealed their SPF rating was lower than claimed.
Consumer NZ is now calling for mandatory standards for the industry.
A Consumer NZ test found the Pure Blend Sunscreen SPF15++ in reality had an SPF rating of just 4.
The sunscreen, which was marketed as a natural product, would be pulled from shelves.
Consumer NZ chief executive Sue Chetwin said the same was applicable to Snowberry Family+ Sunscreen SPF30.
