A hostel at Ōtorohanga College has been closed as a precaution out of fear whānau members were possibly exposed to person who has tested positive for COVID-19.
A post on the the Waikato school's Facebook page said "a positive COVID case was on a flight out of Wellington to Hamilton" where the exposure could have happened.
It said the whānau members then attended a community meeting in Kawhia.
"As a precaution, and in the interest of keeping safe, we are asking everyone who has had contact with anyone at the meeting to urgently get COVID tested and to isolate until you get a negative test.
"As a precaution the hostel will be temporarily closed until we can ensure it is safe to reopen... We are confident we are being proactively cautious and will keep everyone posted."
It said anyone who had had contact with people in the area's coastal communities in the past day should get tested and remain isolated.
In a statement, Waikato DHB said it is in contact with Ōtorohanga College, but considered the individual in question to be a casual contact with minimal risk of exposure.
"They have been tested and the result is pending," it said.
"As, based on current information, the students would be considered casual contacts of someone who was also a casual contact, the DHB's public health team has advised the school it may continue to operate as normal at this time."
