Mr Gane suggested a fine of between $50,000 and $10,000.
Juken's solicitor, Brad Alcorn, said Mr Wilkins, an experienced employee of 11 years, had breached safety regulations when he entered the area to check the jam.
"There are strict rules around approaching and remedying jams," Mr Alcorn said.
Mr Wilkins has since lost his job at Juken and Mr Alcorn said it was a result of his breach of conduct, rather than the accident itself.
Mr Alcorn said there had been no other accidents in that particular area.
Juken have since installed a lock and barrier gate system.
Judge Tom Broadmore said Mr Wilkins' arm injuries were serious and he could have faced a "far worse fate".
Judge Broadmore said Juken could have prevented unauthorised access to the area by locking the gate.
"Steps that have since been taken.
"Juken submits that it was not obvious that other protective measures were needed but I respectfully disagree," Judge Broadmore said.
Judge Broadmore made reference to Mr Wilkins' victim impact statement in which he discussed how he had been left with permanent nerve damage, was now unemployed at the age of 58 and felt it would be difficult to gain future employment.
"Mr Wilkins also expressed a concern that Juken appeared unsupportive and he had no contact from them to find out how he was going," he said.
In imposing a fine, Judge Broadmore took into account the scale of Mr Wilkins' injuries.
"I also recognise the terror Mr Wilkins would have felt in regard to more serious injuries had he not failed to stop the machine."
He said the bulk of the burden rested with the employer.
Judge Broadmore said Juken had been operating in Wairarapa for about 20 or 30 years and had faced 12 convictions, which he saw as a mitigating factor due to the size of the company and its complex machinery. "It's a large employer and, in my general knowledge, a good employer," he said.
