Police were called to an Auckland hotel on Monday because of concerning behaviour by a person who was in quarantine.
The person had a mental health episode which required two separate police call-outs.
Air Commodore Darryn Webb said the person had returned from overseas and was quarantining in Jet Park Hotel in Māngere.
"He had a mental health issue," Webb told reporters at a press conference this afternoon.
"The onsite staff did a great job of calming him, getting him back to his room, but that escalated once again.
