This data was used to compare different ethnicities. We compared New Zealand Europeans with those identifying themselves as Maori.

A total of 69 cases were identified as Maori. The incidence of CM among Maori is 2.7 per 100,000. Maori had significantly greater Breslow thickness compared with New Zealand Europeans (1.3 vs. 0.80\u00a0mm, <jats:italic>P<\/jats:italic> &lt; 0.0001).
