New Zealand police destroyed approximately 124,000 cannabis plants and arrested 780 offenders during the national cannabis operation of the 2007-08 growing season.[1] The operation, named Operation Julia, ran across the November-to-March growing season, when growers trespass on farms to hide plots among tall maize crops and on unused land.[1][2]

In Northland, police arrested more than 200 people on drug offences and seized more than 45,000 cannabis plants during Julia.[2] Ahead of the next season, rural Taranaki police asked landowners to watch for strangers and vehicles, to check for signs of interference, and to report anything relevant, with all calls kept in confidence.[1]

Bigger season to follow

Police said the follow-up National Cannabis and Crime Operation, Operation Kristy, which started the next December and finished at the end of March 2009, produced more arrests and more cannabis than Julia.[2]
