Police in Auckland say there has been a dramatic increase in the number of high school students being used in the importation of illegal drugs.
Organised crime groups are targeting mainly Asian students, using them as what is termed "catchers", where the students receive parcels containing pseudoephedrine.
The Metro Drug Squad says students are paid up to $1000 for each parcel they collect.
Detective Senior Sergeant Chris Cahill says criminals get a student to either accept mail posted to their address, or to wait outside an address that a courier is delivering to.
He says the packages contain a flu drug called Contact NT which contains pseudoephedrine used to manufacture the drug methamphetamine, also known as "P".
Mr Cahill says police are trying to educate school students and the Asian community about the serious consequences they will face if they get involved in such activity.
