This analysis included all new registrations of and deaths from myeloma recorded by the Ministry of Health, New Zealand, between 1985 and 2016. A total of 7,826 New Zealanders were registered with myeloma during the study period. Since 1985, the incidence of myeloma has significantly increased since 1985; the age-specific incidence of myeloma increased significantly for men. The incidence of myeloma is higher among Māori and in non-Māori, and higher in men than in women. Overall mortality rates have fallen since the late 1990s. Throughout the study period, mortality rates were uniformly higher among men compared with women. Mortality has fallen since 1995–1999 for women, and since about 2000–2004 for men. Myeloma mortality was highest in Māori men. While survival has improved significantly since 1990, the risk of death remains higher among Māori than among non-Maori.
