Cannabis plants were discovered at houses in Te Puke (35 plants), Tauriko (31 plants) and Bethlehem (49 plants). The plants were in various stages of development.
Those arrested face a variety of charges including possession and supply of Class A and C drugs, cultivating cannabis, possession of drug utensils, receiving stolen property and breaching court bail.
About 40 officers took part in today's operation, including armed officers and police dogs.
Detective Sergeant Darryl Brazier said: "We have sent a clear message today that we will not tolerate drugs in our community. We will continue to shake the trees until those people intent on criminal offending realise that they have nowhere to hide and that they need to start doing something more productive with their lives."
