An Auckland high school has placed CCTV cameras in its bathrooms, in a bid to stop vaping

Green Bay High School students have taken to social media to voice their concerns, saying it's a breach of privacy.

The school has also installed a glass door to a new bathroom.

Auckland University senior law lecturer Nikki Chamberlain says children are vulnerable when it comes to privacy.

She says schools are more likely to face scrutiny from courts for their actions because of that.
