Police in the New South Wales Riverina region are searching for a man who carjacked a driver at gunpoint before forcing him to travel almost 200 kilometres.

A 35-year-old man told officers he was driving through Griffith yesterday when a man with a pistol jumped in front of his car and demanded to be driven to Wagga Wagga.

The driver dropped the gunman off and was not hurt.

Inspector Stephen Radford says the suspect is in his early 30s with shoulder-length black hair and facial hair.

"Any man that abducts someone in a car with a firearm would have to be treated with a great deal of caution," he said.

"If any members of the community come across this person, we urge them not to approach them under any circumstances."

He says it would have been a terrifying ordeal for the driver.

"[Carjackings are] unusual for obviously Griffith and Wagga and it's something we treat quite seriously," he said.

"The victim in the matter wasn't injured, which is a good thing, and he's at home recovering from his ordeal now."

Police say anyone who has seen the man should call triple-0.
