Hi
Kits are not illegal, I don't think anybody is going to prosecute anybody for a kit.
Kits are available in NZ
NZ pills have changed a lot in the last 6 months, years ago there used to be mainly MDMA, but in the last 6 months there has been a trend away from MDMA, many pills will contain BZP and other phenylpiperazines which a reagent test kit won't pick up*, some will have a degree of MDMA to foll a test kit but may also contain things like DXM, or a 2C? or 2CT? or other new 2C or beta-keto analogues, many contain kiwi methamphetamine (P) - the results I have seen coming out of the testing laboratory are things that I'm not sure a reagent test kit would help you with. I'd be concerned about them giving a false sense of security if I was eating pills myself.
Some of the combos have been unpredictable.
Stargate are happy to get your pills tested via GCMS, but please don't send us drugs that might be illegal through the mail. Drugs, like explosives are something you are not allowed to send in the mail.
Especially please don't mail us illegal drugs from overseas.
Phone us on 0800 STARGATE, come in to our office with the sample and we will get it analysed.
Have a nice day.
* edit: I don't know what the capabilities of reagent test kits are, perhaps somebody else can fill in here.
