Operation Crusade In 2001, the
New Zealand Police launched
Operation Crusade, a long police surveillance operation of the Christchurch-based
Mongrel Mob Aotearoa chapter. The main purpose of the Operation was to disrupt and destroy a suspected drug sales-ring controlled by the Mongrel Mob. Over a 15-month period, the Operation targeted the gang using taps on the phones of known Mongrel Mob Aotearoa members and undercover police buying drugs from the gang. The operation culminated in co-ordinated raids resulting in nearly 40 arrests and a "huge trial" in the High Court at Christchurch. Joseph 'Junior' Wiringi and most of the chapter's top hierarchy were arrested in 2003 as part of the police investigation on more than 70 charges, including dealing in methamphetamine and magic mushrooms and possessing firearms. The operation confirmed the suspicions of police and revealed brazen drug dealing from the gang's former headquarters on Wilsons Rd.
Operation Walnut Operation Walnut was a four-month long investigation targeting an organised methamphetamine supply-and-distribution ring operating out of the
Mongrel Mob Porirua in the Wellington region. As well as undertaking 8 search warrants in the Wellington region, the Operation also targeted a property in the East Auckland suburb of
Howick where the Mongrel Mob is suspected of importing the methamphetamine. The operation involved another 150 New Zealand Police officers, with 120 operating in the Wellington raids and the remaining 30 operating in the Auckland raids. From December 2016 to April 2017, it is thought that the Mongrel Mob had distributed over 20 kilograms of methamphetamine, valued at over
$18 million. The first day of raids led to the confiscation of a Mercedes-Benz, a container property, 2 kilograms of methamphetamine, $450,000 in cash, two stolen motorbikes valued at $30,000, and over 13 vehicles, a jetski, 2 boats, valued at $1.8 million. The six-month-long investigation involved over 300 New Zealand Police staff, including the Auckland-based National Organised Crime Group, Tauranga-based
Armed Offenders Squads, and the locally based Asset Recovery Unit. The final number of arrested associates stood at 38 arrested, with more arrests likely to occur The investigation culminated with the raids of over 40 properties, in Kawerau,
Ōpōtiki,
Whakatāne; and 3 properties in
Gisborne and
Hastings; leading to the subsequent arrest of the 30 associates. Also confiscated were residential property, boats, jet-skis, motorcycles, and cars.
