Customs has seized a $40 million shipment of methamphetamine, more than $1 million cash, and cars including a Ferrari, a Lamborghini, a BMW, a Porsche and a Mercedes Benz.
The 40 kilograms of methamphetamine was found in a shipping container at Ports of Auckland by Customs.
The drug was hidden inside marble tea-tables from China.
The discovery of the shipment has led to the arrest of four men - two New Zealand residents and two foreign nationals.
The men appeared in court yesterday on charges related to the importation and supply of the drug.
A further kilogram of methamphetamine was found at an Auckland address following the seizure.
Customs investigation manager Maurice O'Brien said the discovery of the "sophisticated concealment" was testament to the intelligence-led approach customs and police took to identifying and stopping drugs at the border.
Police spokesperson Zane Hooper said large seizures like this show demand for the drug, often called P, is still very strong.
Last year, customs and police intercepted 334 kilograms of methamphetamine, more than nine times the amount seized in 2013.
The Organised and Financial Crime Agency of New Zealand (Ofcanz), which works with police and customs to help dismantle organised crime syndicates is involved in the investigation.
