The Education Minister's not ruling out banning other digital distractions in schools.
An Education Review Office report shows three-quarters of secondary school teachers believe student behaviour's improved since cellphones were outlawed in class.
It's also recommending considering also excluding smart watches and social media.
Education Minister Erica Stanford says she's open to the ideas.
"We're certainly going to take ERO's recommendations into account and I'll get the Ministry to give me some advice, but I certainly think we probably do need to go further. But that'll obviously be a decision I need to take to Cabinet."
