Managed isolation and quarantine staff including New Zealand Defence Force staff assisted by hotel staff, worked to ensure 60 returnees evacuated the premises safely to the designated assembly point.
"Emergency evacuation and preservation of life must always be the priority in such situations.
"The safety of our staff and returnees is our top priority to ultimately ensure the safety of our community."
All isolation facilities operate in a Level 4 environment, the spokeswoman said.
"In evacuation situations where guests need to be evacuated outside, strict infection prevention controls, developed by the Ministry of Health, are followed to manage the risks of spreading Covid-19.
"These protocols include use of PPE and masks and physical distancing rules. All these protocols were followed."
Returnees safely returned to their rooms at approximately 7.10pm when the facility was declared safe.
Cleaning of areas used by returnees during the evacuation has taken place.
