Auckland’s Hidden Cannabis Grow Houses Linked to Vietnamese Syndicates

In a troubling development for Auckland, New Zealand, authorities have uncovered that over 300 homes have been converted into cannabis grow houses by Vietnamese organised crime groups. These operations often take place unnoticed in residential neighborhoods, raising serious concerns about community safety and property damage.

Details of the Operations

According to a report by Stuff, the properties involved are typically rented or purchased in quiet, often affluent suburbs. Once acquired, these homes undergo extensive modifications to create optimal environments for indoor cannabis cultivation. Sources familiar with the operations describe the process as “highly refined,” with one stating, “It’s an art form: and the Vietnamese [crime groups] are very good at it.”

The sophistication of these operations varies, with some syndicates utilizing advanced techniques such as charcoal filters to mask odors, automated heating and irrigation systems, and clever window coverings that give the illusion of occupancy. For instance, offenders have used materials like Panda Film—designed to be both reflective and light-proof—to obscure their activities. Others have employed a combination of blackout curtains and lights to simulate normal living conditions.

Advancements in lighting technology further aid these growers in evading detection, as lower-powered systems produce less heat, making it difficult for police helicopters to identify grow houses from the air. Additionally, some syndicates directly tap into street-level electricity, avoiding detection from unusually high power consumption.

Impact on the Community and Law Enforcement Response

The extensive alterations made to these properties can result in repair bills reaching as high as $500,000 for landlords due to structural damage, ruined wiring, and plumbing issues, as well as the risk of black mould from heat and moisture. One source likened the situation to past street-level drug dealing, stating, “It’s like the new tinny houses.”

The scale of these operations has drawn the attention of other criminal groups, leading to incidents where established gangs have seized crops from Vietnamese growers. Concerns have been raised regarding the police response to these activities, with some sources expressing frustration that the issue is not being prioritized. “There’s the exploitation, the power and water theft, the property damage, the standovers,” one source stated.

Authorities have initiated investigations, such as Operation Bush, launched in December 2021, which specifically targets organised groups involved in cannabis cultivation and money laundering. This operation has led to the seizure of various assets, including properties, vehicles, and cash, as well as phone intercepts revealing coded language used by the syndicates.

Officials have also noted connections between these cannabis operations and other businesses, such as nail bars. Steve Watson, compliance director at Immigration New Zealand, indicated that many growers come from specific regions of Vietnam, hinting at an organised recruitment network. “It does seem to be organised irregular migration… an organised criminal enterprise offshore,” he stated.

Many of those involved in these operations are believed to be young Vietnamese nationals on student or work visas or overstayers, often considered minor players in the larger scheme. As a result, many are deported rather than prosecuted. Judge Richard McIlraith acknowledged the complex circumstances surrounding these individuals, stating, “While you did have a choice not to be involved, the reality is in many ways that choice was artificial.”

Despite uncovering thousands of cannabis plants and millions of dollars’ worth of drugs during recent operations, police have downplayed the scale of the problem, asserting that grow houses are “not a new phenomenon.” They acknowledged, however, that the size and proliferation of these setups have increased significantly in recent years, particularly in Auckland.

Authorities continue to emphasize the dangers posed by unsafe electrical wiring in these makeshift grow houses, which not only endangers those operating the illegal setups but also poses risks to neighboring properties and emergency responders. As investigations persist, the focus remains on dismantling these sophisticated networks and mitigating their impact on Auckland’s communities.
