A 28 year old man will face court again later this week after being charged over the car jacking of a taxi driver in the Hunter region on Saturday.

Police allege Zachary Dowling got into the taxi in Kurri on Saturday morning and asked the 41 year old driver to take him to Newcastle.

He then asked to be driven to a caravan park in Maitland so he could get money for the fare.

When they arrived police allege he produced a knife, kicked the driver in the head and took his wallet.

Police say Dowling forced the taxi driver into the passenger seat, cut the wires to the radio and drove north on the Pacific Highway.

About 7.30am (aest) police detected the taxi driving at speeds of 185 kilometres an hour.

Road spikes were deployed and the car was stopped at Johns River.

He appeared in Port Macquarie court yesterday charged with a range of offences including car jacking and assault.

He has been refused bail to reappear in court on Wednesday.
