* 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 or 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.

Vaccination details

Note:
1. No breakdown by location, ethnicity or age group is available for cases and vaccine data to protect patients' privacy.
2. Cases that are under-12 are reported in the “Under 12 years old” category.

Note: Up to date hospital occupancy figures are reported each day in the Ministry’s COVID-19 media statements. On July 7 2022, the Ministry started switched to reporting only COVID-19 related hospitalisations. Data from the previous 90 days is preliminary and incomplete. Data from the National Minimum Dataset is used as it becomes available. Hospitalisation data reporting is high asynchronous and updates are generally unrelated to current hospitalisations. For a weekly time series see the Ministry's COVID-19 Data GitHub repository.

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.
