Control of more than a million dollar in assets, including a whole forestry block, has been seized from a senior member of the Maketu Mongrel Mob.
In a statement police said they'd secured the forfeiture of $1.17 million in property under the Criminal Proceeds (Recovery) Act, from Valentine Nicholas, who lives in the Bay of Plenty.
This follows a High Court judgment issued last week on the back of two criminal trials where Nicholas was facing charges of money laundering.
Nicholas was found not guilty at a second trial after the first trial ended in a hung jury.
Justice Hinton in the Tauranga High Court found the senior gang member was unable to show evidence of a "legitimate source of income" for a number of years.
