The figures reported here are provisional and will be finalised next year.

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, 2021 or 2022.
In 2022 there were 1,937 deaths where COVID was the underlying cause of death. In 2021 there were 16 deaths and in 2020 there were 25 deaths where COVID was the underlying cause of death, as reflected in this web tool.

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.

Each month Births, Deaths, and Marriages (BDM) sends National Collections and Reporting electronic death registration and stillbirth registration data. The registration data is matched to Certificates of Causes of Death (HP4720 and HP4721), sent in by funeral directors, and coroners’ reports supplied by the Coronial Services Unit.

Additional information on underlying cause of death is obtained from hospital discharge data in the National Minimum Dataset (NMDS), the New Zealand Cancer Registry (NZCR), the NZ Transport Agency, Water Safety NZ, the Internet, and from writing letters to certifying doctors, coroners, and medical records officers in public hospitals.
