Police say further arrests are likely after 40 raids in Auckland and Waikato that netted more than $120 million worth of drugs, cars, property, and cash.
Those targeted are accused of involvement in the importation and distribution of Contac NT, a Chinese cold and flu medicine used as a precursor for methamphetmanine (P).
Police say 330kg was seized - enough to make 100kg of P at a street value of $100 million.
Thirty people have been arrested so far.
