The dogs are trained to detect large amounts of money and are partially funded through the sale of assets forfeited to the Crown.
In total, methamphetamine with an estimated street value of up to $200,000, two litres of fantasy worth $20,000, $200,000 in cash, and assets worth $160,000 including sports cars and a Harley Davidson motorcycle have been seized, said Detective Senior Sergeant Chris Moore from the Organised Financial Crime Agency of New Zealand.
"Our terminations have shown that members of outlaw motorcycle gangs are facilitating and financing large parts of the illegal drug market in Wellington, the Wairarapa, Manawatu and the Hawke's Bay," he said.
Six other people, including a Tribesman gang member, a Highway 61 associate and a Mongrel Mob associate were also arrested at the same time as Liu. Mr Moore said the operation showed rival gang members were co-operating in the sale and supply of methamphetamine and fantasy.
Seizing assets was a strong deterrent to gangs and reduced the ability to offend in the future, he said.
