Women's leather belts sold by the fashion website ASOS have been recalled after the metal studs in them were found to be radioactive.
About 50 of the belts, retailing for around NZ$50, are known to have been bought from the company.
They were made using cheap contaminated scrap metal in India.
The firm issued a recall in January, but details have slipped out only now and ASOS cannot say how many have been returned.
The threat was revealed when US port authorities tested a consignment of the peplum leather belts destined for American customers and found they contained Cobalt-60. Health experts say the substance releases gamma rays and that extended exposure is a known risk for cancer.
