This week's Sol3 Mio concert at Spark Arena and the We Love Aotearoa festival have been postponed due to the new COVID-19 cases.
On Tuesday night, Prime Minister Jacinda Ardern and Director-General of Health Dr Ashley Bloomfield announced four new cases from community transmission had emerged in Auckland.
In response, the city is moving into alert level 3 at 12pm on Wednesday until at least midnight on Friday, while the rest of the country is moving into alert level 2.
Promoters of the Sol3 Mio concert which was scheduled for Thursday say it has not been cancelled but is rather being rescheduled.
"We are disappointed and we know you will be too, but the most important thing is that we all work together to beat COVID-19 again," the operatic pop trio said in a statement.
We Love Aotearoa was planned to take place this weekend on August 15 and 16 at Shed 10 and the Cloud, Queens Wharf in Auckland.
The event was set to "celebrate the team of 5 million" with live music and performances, a virtual reality zone, silent disco, interactive art installations, food trucks and more.
"We look forward to rescheduling We Love Aotearoa and celebrating New Zealand's success yet again. Kia kaha and much aroha to all," says We Love Aotearoa founder Gabe Newell.
Ticket holders to both events will be updated directly when the postponed dates are announced.
