A Rydges Hotel maintenance worker who contracted Covid-19 used a lift shortly after an infected guest in the managed isolation facility, investigations have revealed.
He said if the worker had been infected in the lift, it would most likely have been from a contaminated surface rather than droplets circulating in the air of the lift.
Prime Minister Jacinda Ardern said that showed how tricky Covid-19 was given it shared symptoms with many other health conditions.
Bloomfield revealed the man was tested on August 13 as part of the mandatory testing regime for all workers at managed isolation and quarantine (MIQ) facilities.
Hehir said it was particularly concerning no one has figured out what happened and how.
