In less than three months, Police have seized over a tonne of methamphetamine... more than a year's nationwide supply

The latest is 216-kilograms taken in the Waikato this week, alongside about 100-thousand-dollars in cash - and firearms and vehicles.

Two Kiwis and an Australian were arrested.

Detective Inspector Paul Newman says Police will continue targeting drug syndicates as long as drugs are being shipped here.

He says every kilogram of meth taken out of circulation's protecting New Zealand's vulnerable communities.

Newman says that's where the money's coming from - and it's being piped directly into criminal hands.
