People are urged not to eat meth-laced pills disguised as white lollies that ended up in food parcels because they could be lethal.
Pills of methamphetamine disguised as Rinda-brand pineapple lollies were discovered in parcels handed out by Auckland's City Mission on Tuesday.
Each contained three grams of meth, which is up to 300 regular doses.
If you're affected, here's what you need to know.
Symptoms
Drug Foundation's Ben Birks Ang said they were concerned there could be more pills disguised as lollies out there.
People who have consumed them reported a bitter, chemical taste.
Anyone who may have tried one of these lollies and noticed an unpleasant taste, should spit it out and seek immediate medical help - call 111.
Ang said people who may have consumed the drug should look out for chest pain, racing heart, seizures, loss of consciousness.
It was not possible to get high from touching meth but people who tasted it, even spitting it out quickly, were likely to have felt an impact, he said.
People can also call the National Poisons centre on 0800 764 766.
