Contact tracing

Contact tracing helps notify people who may have been exposed to COVID-19. Find out how it works, what you need to do and the NZ COVID Tracer app.

How contact tracing works

Information on contact tracing, how to support contact tracing if you test positive, and getting alerts from the NZ COVID Tracer app.

Household Contacts

You are a Household Contact if you live with, or spend a night with, someone who has COVID-19. We recommend you test daily for 5 days with a rapid antigen test.

Close Contacts

You are a Close Contact if you had contact with someone with COVID-19 when they were infectious. Close Contacts do not need to isolate.
