Notes: This data is for the Auckland Region, including residents of Auckland, Counties Manukau, and Waitemata DHBs. A map of Regional Council boundaries can be found here. The credible interval is the 2.5th percentile and the 97.5th percentile, the years of expected life at birth is the 50th percentile. Further information on the regional life tables and methods can be found here.

Life expectancy at birth is a summary measure of age-specific mortality rates during a specific period. During 2012–2014, among residents of the Auckland Region, life expectancy at birth was 77.8 years for Māori females, 6.8 years lower than for non-Māori females (84.6 years). For Māori males, life expectancy was 73.7 years, 7.4 years lower than that of non-Māori males (81.1 years).

Note: Ratios in bold show that Māori rates were significantly different from non-Māori rates in the DHB.

There were 142 Māori deaths per year on average during 2008–2012. The Māori mortality rate was twice the non-Māori rate, or 164 more deaths per 100,000.

Ratios in bold show that Māori rates were significantly different from non-Māori rates in the DHB.

The leading causes of death for Māori women were IHD, lung cancer, COPD, breast cancer, and accidents. Apart from breast cancer, Māori mortality rates ranged between 2.4 to 4.5 times as high as non-Māori rates for these conditions.

For Māori men, the leading causes of death were IHD, lung cancer, accidents, diabetes, and COPD. Māori men’s mortality rates were 1.7 to 3.3 times as high as non-Māori rates for these causes.

Data on leading causes of death by ICD chapter are available in the accompanying Excel tables.


Potentially avoidable mortality


Avoidable mortality includes deaths occurring among those less than 75 years old that could potentially have been avoided through population-based interventions (including actions to address the social determinants of health) or through preventive and curative interventions at an individual level.

Amenable mortality is a subset of avoidable mortality and is restricted to deaths from conditions that are amenable to health care.
