The government's ban on party-pills has sparkled a frenzy of sales of the drug.
Parliament voted 109 votes to 11 to make it illegal to possess, supply, or manufacture benzylpiperazine and phenylpiperazine - the key ingredients of party pills.
The ban comes into force next month.
Wellington party-pill retailer Rustin Nahulandran says he sold out of stock within minutes of the new law being passed.
He says he will be replacing the BZP based pills with new ones, and expects them to be just as popular.
He says people will try them just to see what they're like.
Criticism of the law reform from party pill manufacturers has suggested that, instead of turning to non-BZP party pill alternatives, users will be tempted into harder drugs, including ecstasy and P. BZP-derived recreational drugs will now hold a class 'C' classification under the Misuse of Drugs Act, akin to that of cannabis.
While there were strong responses and concerns about the ban, response on a TVNZ online poll on Friday showed a relatively even split between those who were glad that something had been done, and those annoyed by the law change.
Nahulandran expects the new pills will sell for approximately $20.
