A large collection of fine wines, jewellery, property and Louis Vuitton handbags were also confiscated, as the High Court at Auckland ordered that Auckland man Ka Kit Yim forfeit more than $5.3 million in assets.

He is serving an 11.5 year sentence for importing and possessing methamphetamine.

The court ruled his assets and those of his associates were obtained by criminal activity, including money laundering and drug importation, and should be forfeited to the Crown.

The assets included property in Auckland and several high-end vehicles including a 2015 Ferrari 458 Speciale, 2010 Lamborghini Gallardo and Porsche Cayman GTS 2014.

Police Acting Detective Superintendent Craig Hamilton said the police operation, codenamed Fireball, was an extensive investigation into the importation of methamphetamine and the resulting funds laundered into high-value assets.

"Over $5 million worth of ill-gotten gains was stripped from those engaging in high level offending.

"Along with the criminal convictions obtained and the sentences imposed as part of the broader investigation, this shows New Zealand police are working really hard to get methamphetamine and the profit it derives out of our communities."
