Disappointment vaping law changes won't stop new sales near schools and marae.

A loophole in the law banning specialist vape stores from setting up within 300 metres of schools or marae from October, exempts dairies and supermarkets.

The Health Ministry has confirmed general retailers which don't currently sell vapes can still set up after October 1.

Cambridge Middle School Principal Daryl Gibbs told Mike Hosking they had hoped the ban would help.

He says supermarkets and dairies are often closer to schools than specialist vape stores - and it's really disappointing they'll still be able to sell them.
