"The stripping of assets that have been illegally gained is a vital preventative measure because it sends a message ... that crime ultimately does not pay.
"This is the largest seizure from the Waihi-Whangamata area."
More than $30 million in assets has so far been forfeited to the Crown under the Criminal (Proceeds) Recovery Act, while a further $290 million in assets were subject to court restraining orders.
"All of Mr Filer's assets, including the marina berth, will be sold with the profits returning to the community," Mr Hamilton said.
Filer and his co-accused, Steven John Mehrtens, of Whangamata, were found guilty of large-scale methamphetamine production from October 2009 to May 2010.
The pair were arrested in Operation Acacia, a joint inquiry between the Organised and Financial Crime Agency and the Auckland Metro Crime and Operations Support team.
They found a link between an Auckland drug network and methamphetamine cooks in the Coromandel Peninsula which led them to Filer.
The main targets of Operation Acacia, Feng Chih "Daniel" Hsu and Aenoy "Dion" Bouavong, supplied pseudoephedrine to Vietnamese men living in the Coromandel, who on-sold it to a woman. She then passed it on to Mehrtens and Filer.
On Monday, Prime Minister John Key announced that more than $3 million recovered under the Act would be put towards initiatives to break the methamphetamine supply chain and expand alcohol and drug treatment programmes.
