As concerns about Hamilton's Soundsplash music festival grow, some high schools aren't taking any chances.  

At least one Omicron case has been confirmed at the three-day event, and many more are feared. 

More than 100 students from Auckland Grammar went to the festival and have been ordered to isolate at home until they produce a negative test.   

Other schools are advising their students to take the same precautions.  

Auckland Grammar Headmaster Tim O'Connor told Tim Dower it's a no brainer.  

“I’d rather have students off one or two days while they get a negative test result than having to shut down either an entire cohort or large groups.”
