Pene was involved in the manufacture of 770g of meth.
He told the jury although he carried gas bottles, a bag of ice and water to the Taipuha Rd house, and agreed to drive Harding to and from the property, he did not know meth was being manufactured.
Justice Moore said unsurprisingly the jury rejected his argument.
Pene's lawyer Lucy Postlewaight said he acknowledged he had been a childhood friend of Harding and felt obliged to do as he was told without any reward.
He rued his lack of judgment and was looking at being a role model for younger prisoners, she submitted.
Crown solicitor Mike Smith said Pene's level of involvement could not be limited only to the times he was at the Taipuha Rd property and that evidence at trial shows how he was connected to Harding and the drug manufacturing operation.
He said a message needed to be sent to the wider community, including gangs, that those who chose to help in the commercial manufacture of the evil drug, would go to jail.
Justice Moore said Pene met Harding as a teenager and later became a patched member of the Head Hunters' gang. Despite Pene's claim he simply helped an old friend, he would have been aware what was going on in the Taipuha Rd house, the judge said.
"That was an incredibly foolish and short sighted thing to do," Justice Moore said.
He said it seemed Pene's involvement in the drug operation was limited and that he responded to Harding's request for help in an unplanned way.
"Your future rests in you own hands and your own life decisions. I still don't accept you are a lost cause. You have much to live for."
Justice Moore said a letter Pene's wife wrote for the court was beautifully crafted and spoke about his potential.
