This information is presented by prioritised ethnicity, by which each person represented in the data is allocated to a single ethnic group using the priority system Māori > Pacific peoples > Asian > European or Other. The 'European or Other' ethnic group includes persons of the following ethnicities: European (including New Zealander), MELAA (Middle Eastern, Latin American and African), Other and Unknown.
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
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.
