New Zealand police seized 141,000 cannabis plants and arrested 1,125 offenders during Operation Kristy, the National Cannabis and Crime Operation that ran from December 2008 to March 2009.[1] Officers also seized 191 firearms, recovered $400,000 worth of stolen property and located four methamphetamine laboratories.[1]

The haul was the highest in ten years, up 17,000 plants on the previous season, Detective Senior Sergeant Scott McGill told police magazine Ten One.[2] The potential community harm was put at $379 million, based on a conservative estimate of 226 grams of cannabis per plant, and police searched more than 820 houses and properties during the season.[2]

Cultivation-led increase

The year’s increase in cannabis offences was almost entirely driven by cultivation, supply and possession offences detected through the extra resources invested in Kristy.[1]
