As a section of external fencing was being replaced outside the smoking area of Auckland's towering Stamford Plaza a 32-year-old man, newly returned from India and on day four of quarantine, took his chance and escaped from managed isolation.
What happened for much of the next hour is still unclear, but what is certain is at some point the man, who had been tested for Covid-19 and was awaiting results, went into a nearby Countdown supermarket on Victoria St West and bought items at a self-service checkout.
Security charged with guarding those in managed isolation tried to follow him but lost him. The police were called and despite an extensive search of the area he eventually walked back into the downtown hotel around 8pm.
Had he walked directly along Albert St to the Countdown store 450m away, it would have taken just six minutes. If he took the same direct route back, 12 of the missing 70 minutes can be accounted for. Even with a generous allocation of 10 minutes for shopping, there still remains a 50 minutes window where no-one seems to know where he went.
Police are now scouring CCTV footage to determine his movements around Auckland's busy CBD.
The Auckland Regional Public Health authority has also launched an investigation after the second breach of someone in managed isolation in four days.
It's working with Countdown, who were forced to close the store for deep cleaning today, on any contract tracing and testing requirements.
Countdown chose to close, staff self-isolating
Kiri Hannifin, Countdown's health and safety general manager today said the closure of the central Auckland supermarket was the company's decision - not Government officials'.
The Victoria St West Countdown didn't close until 10pm last night after the man's visit, despite police attending the scene, and then reopened at 7am this morning.
Shelf-stackers worked throughout the night, refilling supermarket products at the busy central city store.
"I made the decision to close the store," Hannifin said.
"We were not advised to close the store, nor did we know until mid-morning that the man was Covid-19 positive. We did so because we thought it was the right thing to do."
Eighteen Countdown staff were now self-isolating and would be paid for the duration of their time off work, she said.
The head of managed isolation and quarantine Air Commodore Darryn Webb says CCTV footage from within the supermarket has confirmed there was no close contact between the man and any staff or customers during his time there.
Health Minister Chris Hipkins said the man was wearing a mask and there was low risk to the public.
But as a result of this latest absconding incident, all fences in place at managed isolation facilities across the country are being replaced with 6 feet-high fences.
Webb said they were also reviewing the arrangements in place for smokers, and security in smoking areas.
The man, who is a New Zealand citizen and arrived from New Delhi on July 3 and the latest Covid case in the country, will be summonsed to appear in court after he recovers and is clear to leave quarantine charged under section 26 (1) of the Covid-19 Public Health Response Act 2020.
