He and the complainant lived at the Springs' Flat Caravan Park in Kamo at the time of the offending just over a year ago.
Judge Davis said that in December 2012, Vickery visited the complainant who was admitted to the Whangarei Hospital and offered to look after his affairs while he was away.
The complainant gave him the authority to use his account to pay bills that became due.
On December 10, Vickery withdrew $500, $600 and $800 on separate occasions from an ATM in Whangarei.
The next day, he used $104 on two separate occasions at the Waipu Hotel and also withdrew $600 from an ATM in Auckland.
Three days later, he withdrew $320 from another ATM in Whangarei.
Vickery told police he used some of the money to buy the complainant a toothbrush, razors and a small radio.
He submitted reference letters to court and his lawyer Aaron Dooney asked the court for a merciful approach to sentencing.
Judge Davis said the latest offending was consistent with Vickery's past behaviour and his extensive previous convictions.
No reparation was ordered because he has no means to pay.
