They also discovered a large pile of the drug pre-packaged up, ready for sale.
"There's growing concern about the number of people in our community who are consuming what can only be described as a toxic poison."
Thompson said police were determined to get the "poison" off the street.
"If you happen to be caught up using this drug, do yourself and your loved ones a favour and get help."
Synthetic Cannabis RaidGreat work by our Waitakere staff who seized a significant amount of synthetic cannabis from an address in Ranui last week.
A man was arrested and is appearing before the courts - one of several arrests we've made in the area recently around synthetic cannabis.
As Senior Sergeant Richard Thompson explains, we are determined to do everything in our power to get this drug off our streets - but we also need your help.
If you know anyone who is making or supplying synthetic cannabis, then contact your local Police station or phone Crimestoppers on 0800 555 111. You can also send us a private Facebook message.
We also urge users to stop smoking synthetic cannabis due to the dangers and risk it can cause. If you need help, then please contact the Alcohol Drug Helpline NZ
