Consumer NZ chief executive Jon Duffy says sunscreens should be regulated. (File photo) On Tuesday, Gabriel Letizia Jr, the owner and executive director of AMA Laboratories, a consumer products testing company in New City, pleaded guilty on May 7 to defrauding customers by reporting laboratory test results for panellist testing that was not fully performed. Four former AMA employees have previously pleaded guilty in connection with the fraud. Duffy said a number of New Zealand-based manufacturers had used AMA Laboratories to justify SPF claims. “For many years, manufacturers sent us test reports from AMA Laboratories when our tests found their sunscreens weren’t up to standard. Manufacturers continued to rely on AMA Laboratories’ results despite our tests showing products failed to meet their label claims,” Duffy said.
