Solarium operators will be expected to ban people under 18 and those with very fair skin from using their sunbeds, under new voluntary standards.
Sunbed therapists are criticising the guidelines, which also recommend the maximum UV intensity of sunbeds be cut by 40%.
Indoor Tanning Association spokesperson Gabrielle Brown said no one from the industry in New Zealand was invited to participate in discussions were held jointly by Standards Australia and Standards New Zealand.
Ms Brown said the committee which decided the standards was one-sided, with 80% wanting the indoor tanning industry shut down.
Committee chairperson Craig Sinclair said the association was invited, but did not attend the meetings.
