Melanoma

This section provides statistics relating to melanoma cancer registrations and deaths in Aotearoa New Zealand.

Melanoma is a serious form of skin cancer, and New Zealand has some of the highest rates in the world [1].

Please note that custom mortality data releases beyond 2020 are not yet available because data on external causes of death is not yet complete enough. For more information on the Mortality Data Collection, visit the Te Whatu Ora website.

Melanoma and environmental health

Melanoma is a serious form of skin cancer, and, together with Australia, New Zealand has the highest rates in the world [1]. In 2022, there were 3,116 registrations of melanoma in New Zealand.

Overexposure to UV radiation from the sun is the main environmental risk factor for melanoma. It has been estimated that more than 90% of all melanoma cases in New Zealand can be attributed to UV radiation exposure [2].

Other risk factors for melanoma include:

• fair skin, and skin types that burn or freckle easily

• a history of heavy sun exposure and sunburn, including sunbed and sunlamp use

• family history of melanoma.

There were 3,116 melanoma registrations in 2022

In 2022, there were 3,116 melanoma registrations in New Zealand. The melanoma registration rate has consistently been higher for males than females over the past 20 years. Melanoma was the third most commonly registered cancer in 2020 for males (behind prostate cancer and colorectal cancer) and for females (behind breast and colorectal cancer) [3].

For more information on melanoma registrations, view the surveillance report at the top of this page.

294 people died from melanoma in 2020

In 2020, there were 294 deaths from melanoma in New Zealand, down from 329 in 2019.

The age-standardised melanoma mortality rate was 3.2 deaths per 100,000 in 2020, well under the 2011 peak (5.3 per 100,000) (Figure 1). The decrease between 2015 and 2018 coincided with the introduction of two new treatments for advanced melanoma - Opdivo and Keytruda [4].

Melanoma mortality increases with age and is higher for males than females. In 2020, rates were at least twice as high for males aged 65+ years compared to females in the same age group.

Age-standardised melanoma mortality rates for 2011–20 were highest in the European/Other ethnic group (5.2 per 100,000), almost five times the rate for the next most affected group, Māori (1.1 per 100,000).

Note: A new surveillance report for melanoma mortality will be published once 2021 data is available from the NZ Mortality Collection. In the meantime, the key findings from the 2020 data are above, and a full report for data up until 2019 is available at the top of this page. The trends in the 2019 report are consistent with the 2020 data.
