More than 4000 people are diagnosed with melanoma every year, accounting for 80 per cent of skin cancer deaths in New Zealand.
It has been estimated up to 25 per cent of farmers and growers have had a skin cancer.
Farmers and growers are at higher risk of catching melanoma due to New Zealand's UV radiation intensity, and the time they spend outside.
However, melanoma and skin cancers are preventable and curable diseases.
