The short answer is yes, but a darker skin colour is associated with a reduced risk of developing skin cancers. Current statistics in NZ shows that there may well be a lower risk for Maori and Pacific peoples. One serious issue is that for Maori and Pacific people who do develop melanoma, often these cancers are thicker and more serious [Melanoma.org]. One type of melanoma tends to occur on the soles of the feet, palms of the hand and under the nails in those with darker skins.
