In brief
Consumer NZ tested ten widely available sunscreens and discovered that seven did not meet their labeled Sun Protection Factor (SPF) claims, with one product marked SPF 50 delivering only SPF 14 in laboratory tests. All products satisfied broad‑spectrums, but the findings highlight gaps in regulatory oversight and the need for regular independent testing.
In a study released on Oct. 30, 2026, Consumer NZ—New Zealand’s consumer advocacy group—reported that seven of ten popular sunscreens tested failed to meet the Sun Protection Factor (SPF) levels advertised on their labels. The investigation, carried out in Wellington, highlighted that a product bearing a label of SPF 50 offered only SPF 14 in laboratory conditions.
Consumer NZ sampled ten sunscreens that are widely sold across the country, ranging in price from about $4 to $76 per 100 ml. The tests were carried out under the stringent broad‑spectrum criteria, meaning all ten products met the requirement to protect against both UVA and UVB radiation, though most fell short of their claimed SPF values.
“New Zealand has one of the highest skin cancer and melanoma rates in the world,” said Belinda Castles, a researcher at Consumer NZ.

According to Consumer NZ’s statement, only three of the tested sunscreens met their labeled SPF claims. The agency noted that the findings “highlight the need for regular independent sunscreen testing,” as current regulations do not specify how often sunscreens must be re‑tested. The group added that previous investigations had found some companies relying on test reports that were several years old.
The transparency urged by the group follows similar concerns highlighted by other media outlets. An article in the New Zealand Herald described the same result – seven out of ten sunscreens failing to deliver their claimed SPF levels – and noted the wide price range of the products examined. The Herald report also emphasized that the failures occurred despite the products meeting broad‑spectrum protection standards.
While the study did not reveal specific brands, the lack of alignment between advertised and tested SPF levels has drawn attention from health professionals and consumer advocates alike. Health professionals stress that under‑protective sunscreens can increase the risk of UV‑induced skin damage, including skin cancer, especially in a country with a high incidence of the disease.
The Consumer NZ findings suggest that consumers should exercise caution and possibly look for third‑party lab results when choosing a sunscreen. The consumer group advocates for tighter regulatory frameworks that mandate updated testing at regular intervals to ensure product labels accurately reflect the protection they provide.
