Police said large quantities of chemicals and methamphetamine were seized in the raids on properties in Cambridge, Waitomo and Oruanui yesterday.
Four people were arrested, the Waikato Times reported.
A Waikato police spokesman hailed the operation as a major success in the fight against P.
About 80 officers from Waikato, Bay of Plenty and Auckland were involved.
