Police and Customs are working on how to better spot packages from overseas that may be linked to drug production and supply, after busting a sophisticated cannabis operation in the lower North Island, Radio New Zealand reports.
More than 200 cannabis plants were seized and 11 people were arrested following yesterday's operation in Wellington and Whanganui.
Police said the group had sold hundreds of thousands of dollars worth of the drug over the past few years.
Investigators have discovered a syndicate had been importing cannabis seeds from Europe and LED growing lights from China.
