Her fellow drug-pushing grandmother, McMahon, is being asked to hand over six properties and a fleet of luxury cars after earning millions of dollars from selling cannabis.
Drug dealers make up most of asset and cash seizures, but cops are going after other criminals.
Figures released under the Official Information Act show murderers, forgers and white collar fraudsters are also being targeted, although in smaller numbers.
Detective Inspector Peter Devoy said the financial crime unit was receiving more requests from Inland Revenue, the Serious Fraud Office and the Ministry of Social Development to help recover assets.
"The basics of organised crime is to make money. Part of that is money laundering, turning bad money into good money, making it appear legitimate," he said.
"Going to jail is seen as part and parcel of the risks of work, but their profits are now in our sights."
What started as a trickle back in December 2009, when the Criminal Proceeds (Recovery) Act was passed, has become a torrent.
The pace of seizures and restraint orders had increased, as police and prosecutors become more familiar with the laws, to such an extent that around $70m has been frozen by court orders in the past eight months. Former Law Commission deputy president Warren Young said the new law had allowed police to target "Mr Bigs" who kept themselves a step removed from criminal offending.
"Where a person has unlawfully benefited to the tune of $30,000 or more, even if you can't identify a specific offence, there is a provision designed to enable you to attack the so-called Mr Bigs, who sit in the background and are the masterminds of criminal activity and have a very significant volume of assets, the origins of which cannot be explained. "These are people who get others to commit criminal activity on their behalf." Civil rights advocates like Peter Williams, QC, have questioned whether there is enough protection for ordinary people, because the standard of proof for seizing assets is lower than that required for a criminal conviction.
Devoy said police had won a number of forfeitures where the defendant has been found not guilty such as Paul Szeto. Police seized the sickness beneficiary's luxury cars despite him being found not guilty of methamphetamine dealing.
Young said there were enough checks and balances to ensure the law was being used correctly.
