She said that while the Government said it was doing a good job by minimising the sale of legal highs, about a dozen countries had banned them.
"That is what New Zealand needs to do. Not even Ministry of Health experts say that these substances are safe."
Mrs Baker-Hogan said the district council had a great opportunity to make a positive stand for young people and families by developing a strong Local Approved Products Policy (LAPP).
