It's unclear how far meth-laced lollies could have been taken across Auckland.

The Rinda brand pineapple lollies were donated to Auckland City Mission, and given out in food parcels.

Drug Foundation Executive Director Sarah Helm says each lolly has about 300 doses of meth.

She says even a single suck is dangerous.

"There's still a range of effects, so you're likely to still feel an effect - possibly still needing to seek medical attention."
