A man escaped from the managed isolation Sudima Hotel in Rotorua last night.
The person was located within half-an-hour near the facility.
Air Commodore Darryn Webb, head of managed isolation and quarantine, said the person was taken to hospital for support and assessment.
Risk to the public health is low, officials said.
The man was reported missing from his room at 11pm on Wednesday. Defence Force staff found him at about 11.30pm.
Initial information is that the man exited through a fenced area.
Police enquiries are underway, including a review of CCTV, but indications are that he did not move beyond the immediate area, and there is no information to suggest the man came into contact with any other person while he was outside the facility, Webb said in a statement.
Due to concerns for the man's wellbeing he was taken to hospital where he is receiving support and assessment.
Public Health officials say the Covid-19 health risk has been assessed as low.
The man arrived in New Zealand from Brisbane on 8 September, and tested negative for his day 3 test. He is on day 9 of his stay and is symptom-free, and his next scheduled test is due around day 12.
Webb said security has been bolstered at the facility and they will review whether any additional measures are required. Standard Covid-19 procedures are being followed for staff who were in contact with him.
