A P-manufacturing "kingpin" has been sentenced to 17 years in prison for producing up to 1.1 kilograms of methamphetamine.
Wayne Peter Van de Ven, 52, was arrested in April 2010 with a police raid of his Jupiter St, Papakura property netting drugs, thousands of dollars in cash and weapons.
He was found guilty at trial on June 19 last year of 10 counts of manufacturing methamphetamine, 35 counts of supplying the drug, and one count each of conspiracy to supply, possession of a firearm and possession of a restricted weapon - a stun gun.
Prosecutor Ben Finn said Van de Ven was the "kingpin and epicentre" of the "large scale" operation.
Despite the drugs, money and weapons found at his house, Van de Ven still maintained his innocence.
He had since admitted he used methamphetamine, saying it "helped him sleep".
At sentencing in the High Court at Auckland today, Van de Ven's lawyer, Peter Kaye, said there was "not a great deal that could be said on the prisoner's behalf".
Justice Mark Woolford said Van de Ven was being sentenced on 11 manufactures that occurred between January and April 2010.
The judge determined that the group produced between 793 grams and 1.099kg.
An attempt to force forfeiture of Van de Ven's house as a proceed of crime failed after it was successfully argued that it belonged to Van de Ven's father rather than him.
Justice Woolford jailed Van de Ven for 17 years with a minimum non-parole period of eight and a half years.
