South Auckland students video themselves smoking weed at school on Facebook live

A south Auckland principal says he's "very disappointed" in a group of 12-year-old students who filmed themselves smoking cannabis on school grounds, in a Facebook Live video.

But, Southern Cross Campus principal Robin Staples told Newshub there are even bigger consequences for the individuals, now that what they may have seen as "a bit of a laugh" now has police involved.

Footage shows three young boys in school uniform smoking weed through a pipe fashioned from a Mountain Dew can, all the while laughing and commentating on the situation.

"Look at these mean buds," the boy in the middle says, flashing the drugs at the camera.

"Hit it, hit it," another says.

The video went live on Thursday afternoon.

Mr Staples told Newshub young people "get into these things at times and make mistakes".

"It's a challenging area because all of the apps now are becoming so available to young people and I think at a young age they think it's a bit of a laugh and they show off a bit.

"I think they'll have a very changed attitude when they go in front of our board of trustees."

All three children have been suspended from school and will appear in front of a board of trustees. Mr Staples says as it is a criminal offence, police will also be involved where necessary.

"We've had silly behaviour every now and again by students and it's unfortunate because it labels them."

Mr Staples says the school will continue to work with students around how to appropriately engage with social media.
