WELLINGTON, July 10 - Far North's Te Kura Kaupapa Maori o Kaikohe school has been hit by "serious vandalism" and police blame five teens all under the age of 14.

Three classrooms were "significantly vandalised" on Sunday, police said in a statement.

Several family members of the alleged young offenders contacted authorities and are assisting police with enquiries as a result of public outrage, and have offered to help clean up.

Pictures and videos of the destruction was posted to the Te Kura Kaupapa Maori o Kaikohe Facebook page, which alleges the offenders broke through the windows.

Five teens, all under the age of 14, were believed to have been involved.

"It's pleasing that families of these young offenders are holding them to account and making them take responsibilities for their actions," said Senior Sergeant Brian Swann. 

"These senseless and destructive acts are devastating to small communities and we praise the families who are trying to do the right thing," 

The five have been referred to Youth Aid.

Clean up can't begin until insurance assessors have been through, Te Kura Kaupapa Maori o Kaikohe said on Facebook.
