The Government is changing the law to ban those under 18 from using sunbeds.
Associate Health Minister Jo Goodhew said World Health Organisation statistics show the risk of skin cancer increases by 75% when sunbeds are used before a person reaches the age of 30.
Mrs Goodhew said more than 300 people die of melanoma each year in New Zealand, which along with Australia, has the highest rate of the cancer in the world.
The Health Act will be amended later this year to prevent those under 18 from using commercial sunbeds.
The measure was in a members' bill from the Hunua MP Dr Paul Hutchison.
Other strategies in the bill include promoting sun safety, improving training for health professionals and treating cancer faster.
