Counties Manukau Police recovered cannabis, methamphetamine, cash, chainsaws, mountain bikes, clothing, and electronic goods in a gang bust targeting the Tribesmen and Killer Beez.
Police arrested eight people aged between 24 and 64, and searched eight residential addresses yesterday.
Those arrested face a number of charges including the supply and sale of drugs.
Detective Senior Sergeant Kevin Tiernan said the latest raid was part of continuing efforts by the Counties Manukau CIB to combat drug related offending in the area.
"The effect of drugs in the community is devastating and police will take swift actions to hold those offenders to account who try to spread harm through supplying and selling illicit drugs."
