Te Tai Tokerau Principals' Association president Pat Newman suspects that methamphetamine is now harming children in every classroom in Northland.
"Rampant" use of the drug in the North was affecting so many families it had become a major concern at schools, and he doubted that there was a class in Northland that did not have a child who was somehow affected by it.
"That could be, at the very worst, living in a house where it is manufactured and breathing in the fumes, through to parents using the money for [drugs] that should be on food, to seeing violence that goes with P," Mr Newman told Newstalk ZB's Early Edition.
I think it's the community that needs to say, 'Look, we own this problem'.
Mr Newman made his comments in the wake of two primary school-aged children reportedly being caught taking methamphetamine to school, although he had not heard of these incidents.
