It's been confirmed the person who attended three gym classes in Auckland before testing positive for Covid-19 is a healthcare worker at the country's only quarantine hotel.
It's likely the worker contracted the virus at the Jet Park near Auckland Airport, but exactly how is still being investigated by health officials.
Authorities have urged 89 close contacts who attended gym classes at Takapuna's Les Mills to self isolate and get tested.
