Fire investigators were today sifting through the charred remains of a classroom block gutted by fire at Hari Hari early last night.
Six rooms in the technology block at South Westland Area School were either destroyed or badly damaged in the blaze, which is believed to have started in the home economics room, shortly after 7pm.
Hari Hari Volunteer Fire Brigade chief fire officer John MacIntosh said the building was well involved when they arrived, and back-up was called from Whataroa.
Mr Macintosh said firefighters worked for more than two hours to contain the fire, with two crews working inside, and another on the roof removing the iron to douse the flames from above.
Principal Ross Brockbank said the school was closed today and would remain closed until Tuesday, while staff and the board of trustees worked out a re-occupation plan.
