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 2014 was extracted from the New Zealand Mortality Collection electronic records on 24 July 2017. Rates have been re-calculated for data on deaths registered between 1996 and 2014, to reflect ongoing updates to data in the New Zealand Mortality Collection (eg, following the release of coroners' findings) and the revision of population estimates. This has resulted in small changes to some numbers and rates from those reported in previous publications.
At the time of data extraction, there were 543,262 deaths registered from 1996 to 2014. Included in this data were 476 deaths provisionally coded (awaiting coroners’ findings) and 25 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.
