The man who died at an Auckland Managed isolation facility was a 44-year-old Recognised Seasonal Employer (RSE) scheme worker from Vanuatu.
He died on Wednesday night at the Crowne Plaza.
A managed isolation and quarantine (MIQ) spokesperson told Newshub an ambulance was called to the facility at about 7:30pm to attend a "sadly fatal" non-COVID-19 related medical incident.
"Our thoughts are with the deceased's family and friends at this difficult time," the spokesperson said.
Head of MIQ Jim Bliss told Newshub, MIQ staff did their best to assist the man while the ambulance was en route.
Support is being offered to all those in the facility including 155 other RSE workers who arrived with the man on Wednesday afternoon.
Bliss said it's a tragic situation for his family and those he travelled with.
“We are doing all we can to assist these RSE workers who are on their first day of 14 in managed isolation and who no doubt will be finding this very upsetting. Our thoughts are with them and his family. Staff on-site at the Crowne Plaza are providing support to all those who require it.”
It's the second death to occur in a New Zealand MIQ facility, in December a 63-year-old man returning from the Pacific Islands died at Auckland's Grand Millenium.
The man had no COVID-19 symptoms and his death was referred to a coroner.
