Four adults have been injured after reports of a lightning strike on the grounds of a special needs school in Hamilton.
Emergency services were called to Hamilton North School at 2pm on Monday and ambulance staff are still in attendance at the scene.
Principal Tony Kane told Newshub he heard a loud bang before smoke alarms began going off.
He said it was a scary experience for everyone at the school.
"I found one of the classes closest to the strike, and there were a few [students] in there that were badly shaken."
A local shop owner told Newshub she saw ambulances heading to the scene after the "loudest thunder and lightning [she'd] heard in a long time".
Photos show where the lightning forked through the grass on the school field after striking a goalpost.
