Over a quarter of a tonne of methamphetamine concealed amongst a shipment of beer has been seized by police.
So far 328kg of methamphetamine has been recovered in crystalised form from the industrial address, after a search warrant was executed in Ryan Place, Manukau in early March, police announced today.
That figure was expected to increase.
Two men remain before the Court on serious drugs charges, a statement said.
"Analysis is continuing into methamphetamine in liquid form that was recovered at the same time," police said.
"This is a significant volume of work and Police will provide further updates once this analysis is completed."
