The Ministry of Health has confirmed a fourth positive test for COVID-19 in New Zealand.
This positive result is for a New Zealand citizen in his 30s, the partner of the second case announced earlier this week.
The Auckland couple had travelled to northern Italy.
The ministry says the man has been in self-isolation at home since Wednesday and does not require hospital-level care and neither does anyone else in the family home.
It says contact tracing is underway and close contacts are already in self-isolation.
On Friday afternoon, the ministry advised that the man attended the Tool concert at Spark Arena in Auckland last Friday night, 28 February, when he may have been infectious. He was in the general admission standing area in the front left-hand quadrant of the concert.
"We encourage people who were in the general admission standing area to be aware of symptoms of COVID-19. If people are symptomatic, we encourage them to contact Healthline’s dedicated COVID-19 number 0800 358 5453."
Spark Arena and Ticketmaster have worked together to get in touch with concert-goers who were in the general admission standing area in question and may have been close to the confirmed case.
The ministry says this is "what you should do if you were at the concert and were in that area:
· If you now have a fever (over 38 degrees), and a cough, or difficulty breathing, or a sore throat (flu-like symptoms) you should call Healthline’s dedicated COVID-19 number 0800 358 5453.
· if you don’t have any symptoms, please don’t call Healthline.
· Public Health are contacting anyone at risk of infection so remember, the risk is low for all others who attended this concert."
On Wednesday, the ministry's Deputy Director-General Māori Health, John Whaanga, told Te Ao that whānau Māori should follow some simple steps to help safeguard their health.
"We need to wash our hands, if you're sick stay home. If you're sick, ring Healthline to see if your symptoms are consistent with Covid-19."
Healthline's dedicated COVID-19 number is 0800 358 5453.
