Gibbons also applied for grants from gaming machine societies for bowling green maintenance, using the money to illegally repay loans for the purchase of pubs.
He fabricated quotes and invoices from greenkeeping contractors to support grant applications and the provision of services.
None of the contractors named in the invoices knew about the work they were supposed to have done.
Judge Blackie said Gibbons' offending was a "very elaborate" scam and an "unlawful scheme".
He said Gibbons knew he acted dishonestly each time he made a false application.
Speaking from his home, Gibbons told APNZ: "As far as I can see, that was a personal matter and I took it upon myself to plead guilty. End of story."
Internal Affairs spokesman Maarten Quivooy said he was pleased with the success of the operation.
"A clear message to the gambling sector is this - where we come across deliberate and wilful attempts to take community funding, we will take strong and decisive action to hold people accountable."
