Melanoma affects many New Zealanders

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

In 2019, there were 2,727 melanoma registrations in New Zealand. The melanoma registration rate has always been higher for males than females over the past 19 years (Figure 1).

362 people died from melanoma in 2016

In 2016, 362 people died from melanoma in New Zealand. The mortality rate has stayed consistently higher for males than females (Figure 2).

New Zealand has one of the highest rates of melanoma in the world

New Zealand and Australia have the highest rates of melanoma incidence and mortality in the world (Figures 3a & 3b).

Melanoma rates among European/Other ethnicity is five times the rate among Māori

In 2019, almost all melanoma cancer registrations were for people of European/Other ethnicity (2610 out of 2727 registrations, 96%). Only a small number of registrations were among Māori (70 registrations), Pacific people (6 registrations) and Asian (7 registrations).

Melanoma among European/Other ethnicity is five times the rate among Māori. Males had a higher rate than females in the European/Other ethnic group (Figure 4). This has been consistent since 2001–2010.

The percentage of thick melanomas were greater for Māori than non-Māori

In 2019, the percentage of melanomas with thickness larger than 2mm were greater for Māori compared with Non-Māori (Table 1) despite the lower age-standardised rate in Māori.
