John Paul College in Rotorua was briefly forced to enter lockdown yesterday afternoon after students allegedly spotted people nearby wielding firearms.
A police spokesman said this morning no arrests had been made, no items of interest were found and there were no further lines of inquiry.
Police received a report about the alleged sighting just before 1pm and advised the school to enter lockdown.
"Students reported that they saw youths with that they thought were guns in the reserve near Fordlands," John Paul College principal Patrick Walsh said.
"They reported to senior management and they thought as a precaution to call the police."
Walsh told the Rotorua Daily Post all students and staff were safe.
The alleged youths carrying firearms were in Recreation Reserve, not on school property. Police advised the school to go into lockdown after the alleged sighting was reported to them.
"I just want to stress students and staff are safe and we're following the textbook approach to lockdowns," Walsh said at the time.
"Police and the school are handling it well."
