Two men have been arrested and assets worth $5 million seized after two police raids, one of which discovered a "very large underground bunker" for cannabis growing, in the South Island.
The bust is the result of a covert investigation into the commercial cultivation and widespread supply of cannabis throughout the West Coast and Canterbury.
Farm and residential property, cash, bank accounts, vehicles and gold claims (permits to explore/mine) worth about $5m were seized by police.
A 72-year-old Ngahere man was arrested on September 9 and a search warrant executed at his address.
He has been charged with possession for supply of cannabis and is due to appear in Christchurch District Court on September 30.
