Rooms of cannabis was discovered when dozens of police officers swooped on a rural Waikato property today.
At dawn, more than 40 officers from Hamilton, Bay of Plenty and Auckland raided the property off State Highway 23, at Whatawhata, 13km west of Hamilton.
Acting Hamilton City Commander Inspector John Kelly said the property had three residential dwellings on it and several outbuildings.
"At this time large quantities of cannabis have been recovered and two men aged 47 and 48 have been arrested on cultivation of cannabis and possession for supply charges while a woman is helping us with our enquiries in relation to possession of cannabis and methamphetamine."
Police had to close SH23 between Raglan and Hamilton for about 20 minutes for "public safety" because guns were known to be at the house.
