John Paul College is under close watch with up to 30 students returning from a trip to China, and many homestay families are concerned as Chinese students begin to arrive in Rotorua.
"We're doing the best to get our head around it, there are some aspects that are unknown and posing potential risk," said principal Patrick Walsh.
"We're not trying to cause panic. There are concerns that people returning may not show symptoms for up to two weeks and airport checks won't work."
Parents around the country would normally be celebrating as children head back to school, but some might be reconsidering.
After last week's health scare with four tourists admitted to Rotorua hospital for possible coronavirus, principals are on high alert. But they're taking steps to ensure the safety of Rotorua children.
