There are no new cases of Covid-19 in the community today.

Prime Minister Jacinda Ardern and director general of health Ashley Bloomfield will hold a press conference at 3pm after a Cabinet meeting.

The last community case reported is Case O which is a household contact of Cases I, J, K and L who all are in the Auckland quarantine facility. Case O was reported last night.

They were moved to the Jetpark Hotel as a precaution on February 23 so were in quarantine during their infectious period which means there is no risk of spread in the community.

Case M and N - the 21-year-old who went to the gym after getting tested for Covid and his mother - have also been moved to the Jetpark along with their other household family members.

Contact tracers have identified 21 close contacts from the Manukau Institute of Technology who are being followed up with.

Health officials said to check the Ministry's website for the specific times where there could have been exposure to the virus.

"The vast majority of people on the campus at the same times as Case M are considered casual contacts and need to watch for symptoms. They do not need to have a test unless they have symptoms, or are a close or casual plus contact. All casual contacts should be limiting their movements and interactions with other people. Under Level 3, everyone in Auckland should also currently be staying at home."

There have also been 154 casual plus contacts identified from the student's visits to City Fitness Manukau and Hunters Plaza. These people need to stay home until they get a negative test result.

If you were at the gym on February 20 between 12.20pm - 1.45pm or February 26 between 3.25pm - 4.30pm and have not been contacted then please phone Healthline for advice

The first three cases from the Valentine's cluster - cases A, B and C - have now recovered and left the quarantine facility.

There is also ongoing wastewater testing happening near Papatoetoe High School which continues to be negative.

This morning, Ardern revealed there was a clear chain of transmission to the latest two cases which plunged Auckland into level 3 lockdown for a week.

Family members of the newest cases had contact with people from the second case during the last 72-hour lockdown when they were meant to be isolating.

While infectious, the 21-year-old then visited a number of high-risk environments, including the Manukau Institute of Technology, work and the gym.
