A series of drug raids across South Taranaki led to four arrests on Wednesday afternoon.
About a dozen officers searched three homes - in Opunake, Hawera and Patea.
There was no connection between the three properties and their occupants.
Sixteen cannabis tinnies plus $50 was recovered in the Patea house, while cannabis was also found in the Hawera and Opunake properties.
Constable Chris Momney said the Opunake Volunteer Fire Brigade helped with extra lighting for the search of the house there.
She thanked the public for information which helped them with the operations and encouraged people to keep coming forward.
In Hawera, a 51-year-old woman has been charged with three counts of selling cannabis and one charge of possession for supply.
A 40-year-old man was also charged with being party to selling cannabis and cultivation.
In Patea, a 56-year-old man has been charged with selling cannabis and possession for supply.
A 52-year-old Opunake man was arrested for possession of cannabis, possession of cannabis utensils, possession of methamphetamine utensils and attempting to produce cannabis oil.
They will appear in the Hawera District Court on Tuesday.
