Health Minister David Clark will speak to his Cabinet colleagues in the next few weeks about reclassifying two compounds commonly found in synthetics – AMB Fubinaca and 5FABD.
"Those two are cropping up all over the place. While those are the two big ones it's easy to reclassify them. The harm around them is well-documented and reclassifying those drugs as Class A will give police the same search and seizure powers as they have for other hard drugs that cause serious harm," Clark said.
Clark acknowledged that it was not going to be possible, with new drugs coming into the country all the time, to ban all new substances.
"That's the reality. But we are moving, where it's sensible and obvious that drugs are causing harm, to interrupt supply as part of as health response."
Clark said he would be seeking Cabinet support in coming weeks. It would not require a law change so the change could be swift once a decision was made.
