The MIQ facility believed to be the gateway that let the Delta variant of Coronavirus into the community is now empty of guests.
Auckland's Crowne Plaza hotel is being investigated as a possible source of transmission after a New South Wales returnee was staying there prior to testing positive for Covid-19 and being transferred to Jet Park.
Managed Isolation and Quarantine joint head brigadier Rose King said the Crowne Plaza was currently empty because the most recent cohort had left after completing the mandatory two weeks.
The next cohort is not due until September 9.
