Cannabis remains a lucrative illicit enterprise and police raids over the past 12 months have netted thousands of plants growing under lights in rental properties, often powered by stolen electricity diverted from neighbouring addresses.<\/p>\n
Many of those arrested were Vietnamese nationals<\/a>, duped into coming to New Zealand on false promises of employment, often after paying tens of thousands of dollars to unscrupulous immigration agents to obtain visas.<\/p>\n Instead of working in the legitimate jobs they were promised, the exploited migrants were forced to tend the cannabis plants as \u201ccrop sitters\u201d to repay their supposed debts.<\/p>\n Police arrested 30 people in Operation Beryl and most were Vietnamese nationals who now face deportation.<\/p>\n The raids targeted 120 addresses spread across the wider Auckland region, mostly rental properties, with nine tonnes of cannabis found in the Waitemata police district in a two-week period alone.<\/p>\n Police from the Auckland City district also discovered half a tonne of cannabis in an industrial warehouse in Penrose, while further south, Counties Manukau detectives found 140kg of cannabis and 4200 plants. <\/p>\n Growing cannabis is not the only illegal activity being committed, McNeill said.<\/p>\n \u201cWe know these rental properties are often fitted out with shoddy electrical wiring, fuelled by stolen power which is diverted from other properties. <\/p>\n \u201cIt\u2019s not only illegal but poses very real dangers to those operating the grow houses and innocent members of the community.\u201d<\/p>\n In some cases, McNeill said the indoor growing systems have started fires in the converted residential homes. <\/p>\n And while police are working hard to target the crime rings, McNeill said landlords need to pay attention or risk insurance not paying out.<\/p>\n \u201cLandlords need to remember they have obligations to carry out due diligence on prospective tenants,\u201d McNeill said.<\/p>\n \u201cIf tenants move in and turn your house into a growing operation, you risk being liable in the event of a fire or significant damage.\u201d<\/p>\n He recommended that private landlords take basic steps such as checking references, meeting tenants face-to-face, verifying credit and income details, as well as inspecting the properties regularly.<\/p>\n \u201cBe aware if tenants have a preference to pay rent in cash or offer to pay more to avoid inspections,\u201d McNeill said.<\/p>\n While the seizure of 10 tonnes of cannabis is by far the largest bust, cannabis \u2018grow houses\u2019 linked to Vietnamese organised crime have become an exponentially bigger problem in recent years.<\/p>\n Earlier this year, the Herald revealed another investigation, Operation Clementine,<\/a> uncovered how Vietnamese organised crime syndicates exploited the visa system to bring in an illegal workforce.<\/p>\n The joint inquiry between police and Immigration New Zealand identified 38 different registered companies with connections to the properties where the cannabis \u2018grow houses\u2019 were busted.<\/p>\n Those businesses, often in the construction or hospitality industries, were then targeted in raids which uncovered more hidden cannabis crops.<\/p>\n \u201cDuring the operation, it was discovered that 11 companies were found or believed to be inoperative,\u201d according to an Immigration NZ briefing released under the Official Information Act.<\/p>\n \u201cDespite this, 203 individuals who hold valid work visas are still present in New Zealand linked to these 11 companies.\u201d<\/p>\n The briefing said that 14 infringement notices were issued to companies employing staff \u201cin a manner that is inconsistent\u201d with a work-related condition of that person\u2019s visa.<\/p>\n Deportation liability notices were issued to 38 people, while two left New Zealand voluntarily.<\/p>\n \u201cOperation Clementine has resulted in a number of interventions which are helping exploited migrants to exit illegal and dangerous situations,\u201d the briefing said.<\/p>\n Others who had been granted visas are now unable to enter New Zealand, the briefing said.<\/p>\n Immigration New Zealand cancelled 62 visas before they left Vietnam, 14 were turned around at the border, and anyone connected to the network of \u2018grow house\u2019 companies is now on a watch-list.<\/p>\n \u201cWarnings have been placed on Immigration New Zealand systems on all companies selected for Operation Clementine, and on all the directors or \u2018key persons\u2019 linked to these companies, to attempt to mitigate and prevent any future connections with non-compliance and or organised crime,\u201d the briefing said.<\/p>\n Steve Watson, the general manager in charge of investigations and compliance at Immigration NZ, was reluctant to disclose how Operation Clementine started.<\/p>\n But he said some patterns had been noticed that \u201cdidn\u2019t seem quite right\u201d and his staff worked closely with police to solve the problem together.<\/p>\n \u201cWe will use the information we\u2019ve gained from this, the learnings, to help inform how we manage risk going forward.\u201d<\/p>\n Watson said many of the Vietnamese nationals caught up in Operation Clementine came into the country on legitimate grounds.<\/p>\n \u201cOnce they\u2019ve got here, they\u2019ve been talked into, or moved sideways, into illicit work,\u201d Watson said.<\/p>\n \u201cIt\u2019s definitely something of concern because from a victim\u2019s point of view, we want to protect migrants and not see them exploited or involved in criminality.<\/p>\n \u201cBut sometimes they are complicit, or know what they\u2019re doing, and that\u2019s part of the investigation that does take a lot of time.\u201d<\/p>\n The joint investigation was also looking for connections between the directors and shareholders of the 38 different companies linked to the cannabis \u2018grow houses\u2019 that had been discovered.<\/p>\n Going forward, Watson said the main focus of Immigration New Zealand was prevention of migrant exploitation before they even applied for a visa to live here.<\/p>\n One of the concerns for Watson were stories of migrants paying large sums of money to \u201cunscrupulous\u201d agents to obtain visas.<\/p>\n \u201cWe\u2019re talking $10,000 or $20,000. I\u2019ve heard up to $30,000,\u201d Watson said previously.<\/p>\n \u201cThat\u2019s something we want to put a stop to. The correct way to come to New Zealand is to come straight to us [Immigration NZ].\u201d<\/p>\n Although Operation Clementine is an example of co-operation between two law enforcement agencies, a group of experts advising the Government on organised crime has warned that more needs to be done.<\/p>\n \u201cInformation sharing <\/a>between government agencies is deficient. In some cases, that is because there are specific legislative barriers. In others, the willingness to share information proactively is due to the culture of organisations,\u201d the advisory group wrote in March.<\/a><\/p>\n \u201cWe need to have a mature conversation about the privacy settings which balances the need to combat organised crime effectively, without compromising individual privacy interests.\u201d<\/p>\n Jared Savage covers crime and justice issues, with a particular interest in organised crime.
