* The prioritised ethnicity classification system is used in this table and below. This means each person is allocated to a single ethnic group, based on the ethnic groups they identify with. Where people identify with more than one group, they are assigned in this order of priority: Māori, Pacific Peoples, Asian, and European/Other. So, if a person identifies as being Māori and New Zealand European, the person is counted as Māori. See Ngā tapuae me ngā raraunga: Methods and data sources for further information.

The data categorized by ethnicity come from National Health Index (NHI) data collection, linked to data held in the EpiSurv database.

Note: Up to date hospitalisation figures are reported each day in the Ministry’s COVID-19 media statements. These figures are reported by DHBs nationally and there can be a lag in reporting detailed statistics. From February 23, 2022 data provided directly by the 4 Northern Region DHBs is used to supplement the nationally reported hospitalisations. Hospitalised cases are either cases recorded in EpiSurv as being hospitalised or cases who are recorded as being in a Northern Region hospital for more than 24 hours.


Details of COVID-19 deaths

All deaths where someone has died within 28 days of being reported as having a positive test result for COVID-19 are now reported. This approach is in-line with that taken by other countries — such as the United Kingdom — and it ensures that all cases of COVID-19 who die are formally recorded to help provide an accurate assessment of the impact of COVID-19.

In many instances, further investigation will provide more information about the contribution of COVID-19 to their death.

This contribution can range from death not related, for instance someone with COVID-19 who dies in a car accident; to COVID-19 being a contributing cause, for example when someone dies with an existing health condition combined with COVID-19; and to COVID-19 being recorded as the cause of death.

Deaths that are still being investigated are reported as still to be classified.

Of the 461 deaths that have been officially coded as due to COVID-19, 9 occurred more than 28 days after testing positive. In addition, COVID-19 has been coded as contributing to 237 deaths. Of the deaths that occurred within 28 days, 176 have been ruled as not related to COVID-19 and 134 deaths are yet to be classified.
