A Head Hunters pad in Christchurch and range of gang homes and motorbikes may become government property after a court approved their seizure.
The High Court at Christchurch's restraining order comes after a police operation in Canterbury last year led to prosecutions against key Head Hunter members for alleged organised crime and drug dealing.
It also follows on from a recent investigation into a senior Auckland gang member.
Detective Superintendent Iain Chapman said the start of court proceedings aimed at permanently seizing control of the assets was made under the Criminal Proceeds Act.
"The intention of the [Act] is to disrupt, deter, and derail crime, especially in the areas of organised crime and methamphetamine offending," Detective Superintendent Iain Chapman said.
"Our work in this area denies criminals the opportunity to either enjoy the benefits of offending or to reinvest those proceeds in further criminal activity."
If the assets are permanently stripped from the Head Hunters, they are then managed by the Ministry of Business, Innovation and Employment.
Any money raised from their subsequent sale or management is put into a fund with other government agencies bidding to use it for their own programmes.
Prosecutions against Head Hunters members arising from last year's Canterbury operation are still currently before the courts, police said.
