Cannabis found growing in Piha and Muriwai has been seized and destroyed in a $2 million police operation.
More than 2000 cannabis plants were found across Auckland including west coast beaches in a sting targeting cannabis growers last week .
As a result eight people between the ages of 29 and 58 including one woman have been charged with cannabis cultivation.
Police say more arrests are likely.
Operation Lucy led police to find plants growing in forests, swamps, rivers and rural property across Auckland.
The New Zealand Air Force helped police recover and destroy the drugs by using helicopters to winch them into the cannabis plots.
Operation head Detective Sergeant Callum McNeill says some of the plants had been growing a long time and thanked the public for providing information that had led to the arrests.
He encouraged people to phone the police if they noticed suspicious activity in their area such as lights in the bush after dark or people in places you wouldn't expect them to be.
Similar operations will continue across Auckland in the coming months.
