Health authorities are investigating a possible link between an Auckland mall worker who tested positive for COVID-19 and another case.
Dr Ashley Bloomfield announced during Friday's 1pm press conference the two positive cases of coronavirus may have been on the same bus.
"The community case which is under investigation who works at St Lukes Mall has been linked to a current community outbreak using genome sequencing," the Director-General of Health said.
"However there is no yet known epidemiological link with the outbreak and investigations continue into the source of exposure.
"One specific line of enquiry is that this case and another case may have been on the same bus."
Dr Bloomfield took a moment to reiterate the importance of wearing masks, particularly public places such as public transport, and when it is difficult to maintain physical distancing.
"We will update you as that investigation proceeds," Dr Bloomfield said.
