An unemployed Northland man has been sentenced to 19 years behind bars for 18 drug-related charges.
Frank William Murray was sentenced on the drug charges, including multiple counts of manufacturing and supplying methamphetamine, in the Auckland High Court.
Police said the 47-year-old was part of a network of drug manufacturers and suppliers.
Detective Sergeant John Sowter of the Organised Financial Crime Agency of New Zealand (OFCANZ) said Murray's initial arrest came at the termination of Operation Enzone in November 2012.
"This operation was triggered by intelligence gathered by Eastern District staff in Napier in July 2012," Mr Sowter said.
