More than 20 firefighters are battling a large blaze at Whangamata Area School.
Fire service northern communications centre shift manager Scott Osmond said a building about 25 metres by 10 metres was well involved when firefighters arrived.
The fire service was alerted to the fire about 11am.
Five trucks from as far away as Pauanui and Waihi were still battling the blaze and will be for some time, he said.
No one was trapped or hurt.
