The Parole Board decision shows the board received a letter purporting to be from Paul Reynolds of the Carterton District Council.
The letter said Patterson had been offered an interview with the possibility of employment with the council in the horticulture department.
However, when the board contacted the council, they were advised there was no such person as Paul Reynolds nor any horticultural department.
Carterton District Council chief executive Colin Wright said he was contacted by the Corrections Department regarding the letter, which appeared to be written on Carterton District Council letterhead.
"We said no, we've never heard of this before - it's not from us.
"It was a bit of a bolt out of the blue at the time."
Patterson is due to appear in January on seven charges relating to writing forged letters in support of a failed parole bid.
Patterson's parents were contacted by the Times-Age but declined to comment.
Patterson used as many as 123 false identities to claim benefits and was raking in $54,000 a fortnight in benefits - mainly pensions he gained by disguising himself as an elderly man and fooling benefit staff across the country.
When police raided his flat in Auckland in 2006 they discovered $750,000 cash buried in the garden, $200,000 and 18 gold bars hidden under the shower, $13,000 in his car, and boxes of fake birth certificates, bank cards, driver licences and passports.
He had even spent $50,000 creating an elaborate tropical garden behind the rented terraced flat in order to hide his loot.
He was convicted of benefit fraud in Australia and the United States, before he returned to New Zealand to carry out this operation.
His current jail sentence ends in July next year.
