Changes to data collection/processing
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.
Rates of mortality were recalculated from 1996 to2018 to reflect ongoing updates to data in the Mortality Collection, (eg, following the release of coroners' findings) and the revision of population estimates from Stats NZ. Population data used to calculate the rate of mortality was derived from datasets downloaded from the Stats NZ website. Estimated resident population counts are regarded as the best available population, and are used whenever possible as the denominator to calculate the rate of mortality.

About this dataset
The Mortality Collection (MORT) classifies the underlying cause of death for all deaths registered in New Zealand, and all registerable stillbirths (fetal deaths).
Purpose of collection
The Mortality Collection was established to provide data on causes of death for New Zealand’s vital statistics, for public health research, policy formulation, monitoring the effectiveness of health programmes, and cancer survival studies. A dataset of each year’s mortality data is sent to the World Health Organization to be used in international comparisons of mortality statistics.
Method of collection/Data provider
Data from 1948–1995 presented in these tables was sourced from publications in the Ministry of Health Mortality data and stats series.
Data from 1996–2018 was extracted from the New Zealand Mortality Collection electronic records.
