It said there had now been 39 cases connected to the Soundsplash music festival in Hamilton last weekend - including two new cases in Northland, one in Hawke's Bay and three in Tairāwhiti today - and this number is expected to grow as further test results are received.
"Given the increase in cases associated with Soundsplash, the Ministry of Health advises all attendees to get a test, if they have not already done so. If you attended the festival, please let the testing centre know that you were at the festival."
It said two of the four community cases in Canterbury reported earlier in the week have now been confirmed to be Omicron, and there are active cases being treated as Omicron in Auckland, Waikato, Bay of Plenty, Taranaki, MidCentral, Canterbury, Tairāwhiti and Nelson-Tasman.

Three of the eight new cases are onboard the Singapore-flagged Maersk Bogor container ship, which is currently under quarantine at the Port of Tauranga.
The Ministry said more than two dozen of the crew on board the ship - which arrived in port on Friday morning have experienced Covid-like illness. Testing returned three positive results so far.
No one has been allowed off the ship and it is due to leave port tomorrow.

"We could see numbers continue to shoot up into the several hundreds over the next week or so."
