About the data used in this edition

Data from 1948 to 1995 presented in these tables was sourced from publications in the Ministry of Health Mortality data and stats series. Data from 1996 to 2016 was extracted from the New Zealand Mortality Collection records on 07 June 2019. At the time of extraction, there were 606,450 deaths registered from 1996 to 2016. Included in this data were 641 deaths provisionally coded awaiting coroners’ findings and 41 deaths awaiting coroners’ findings with no known cause.

Ethnic breakdowns of mortality data are only shown from 1996 onwards because there was a significant change in the way ethnicity was defined, and in the way ethnicity data was collected in 1995. For more information please refer to the Ministry of Health report, Mortality and Demographic Data 1996.

Disclaimer

In this edition, data for causes of death was extracted and recalculated for the years 1996–2016 to reflect ongoing updates to data in the New Zealand Mortality Collection (for example, following the release of coroners’ findings) and the revision of population estimates and projections following each census. For this reason there may be small changes to some numbers and rates from those presented in previous publications and tables.

We have quality checked the collection, extraction, and reporting of the data presented here. However errors can occur. Contact the Ministry of Health if you have any concerns regarding any of the data or analyses presented here, at data-enquires@health.govt.nz
