How contact tracing works
If someone has COVID-19, the Ministry of Health and district health boards (DHBs) find people who may have been in contact with them to see if they have also been infected. This process is called contact tracing.
There are 2 types of contacts:
- close contacts, and
- casual contacts.
Health services will give advice to both of these types of contacts on what they need to do.
The Ministry of Health has more information about contact tracing, including:
- contact tracing phone calls
- detailed definitions of close contacts and casual contacts
- informative fact sheets.
How you can help
You can help make contact tracing easier for health officials by continuing to keep a record of where you go and who you meet.
