Tatau Kahukura 2024 Table 45 publishes age-standardised rates (2001 Census Māori standard) and an official Māori vs non-Māori rate ratio of 2.34 (95% CI 2.25–2.44). The crude (not age-standardised) ethnicity gap is not in that table, so an explained-by-age share cannot be computed. Further official adjustment for NZDep, obesity, smoking, diabetes, rurality, or access is not published.

Worse

Are fewer people ending up in hospital for things primary care can treat?

Official Māori amenable mortality was 123.8 per 100,000 in 2018–20 versus 52.8 for non-Māori (Tatau Kahukura; age-standardised). Pacific amenable mortality halved from 281.1 to 151.1 between 2000 and 2020. Child ASH admissions were 23,206 in 2025. The 375.6 figure on older pages was all-cause age-standardised mortality per 100,000 in 2023, not avoidable mortality. OECD treatable/preventable mortality is not published for New Zealand.
