There are no cases of Covid-19 today - either in the community or in managed isolation, says the Ministry of Health.
Health officials are yet to reveal whether genomic testing has linked the Hamilton Covid-19 case to others from the Pullman Hotel.
The sequencing will be re-run later this week as the viral load in the sample was so low.
The person stayed in the managed isolation hotel between January 16 and 30 but tested positive on Saturday after isolating at home.
The case is considered to be historic, not infectious and the person has been discharged from the quarantine facility.
