According to the New Zealand Herald, a man infected with coronavirus attended the TOOL concert in Auckland on February 28.
He may have been infectious at the time. He was in the general admission standing area in the front left-hand quadrant at Spark Arena.
The man, the partner of the woman announced as positive on Wednesday, has been in self-isolation since yesterday.
The couple returned from northern Italy last week.
Director-General of Health Ashley Bloomfield told media:
“We encourage all people in the area of the concert to be aware of the symptoms and contact the Healthline if concerned. The advice is that the risk is very low for all others who attended this concert.
“There was no way of tracking the people who were in that area of the concert. They are classed as causal contacts and the advice to them is to call Healthline if they have any symptoms.”
