Data for 2022 is preliminary. Data for 2021 is provisional.
2022 data is preliminary due to the number of deaths with no known cause awaiting coroner's findings. 2022 data for assault, intentional self-harm and motor vehicle accidents are not presented, as these causes are typically more influenced by coronial cases.

This dataset includes deaths where COVID was coded as the underlying cause of death. These deaths are coded to the following ICD classification; Chapter 22 Codes for special purposes > U00–U49 Provisional assignment of new diseases of uncertain aetiology or emergency use > U07 Emergency use of U07. The 3-character code U07 can also include vaping-related deaths, though none were reported in 2020 or 2021.

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.
Please note that Stats NZ recently revised their population estimates for the period back until 2006, based on information from the 2018 Census. This will affect rates for a number of causes of death, particularly for Māori.

The Mortality Collection (MORT) classifies the underlying cause of death for all deaths registered in New Zealand, and all registerable stillbirths (fetal deaths).

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.

Data from 1948–1995 presented in these tables was sourced from publications in the Ministry of Health Mortality data and stats series.
Data from 1996–2022 was extracted from the New Zealand Mortality Collection electronic records.
