Barry Greentree was last seen at his home on Sailfish Street, Corlette at about 11 o'clock last Thursday morning.
There are concerns for the 90-year-old's welfare as he requires regular treatment for a medical condition.
He's described as being of Caucasian appearance with a solid build and fair complexion, about 165 centimetres tall with grey hair and blue eyes.
It's believed he could be heading towards Tamworth and Casino in a blue Hyundai sedan with the rego number BSF 74H.
