Driver charged over NSW Easter smash

A man has been charged over a traffic crash in NSW on the Easter long weekend that left a man fighting for his life and four others in hospital.

The driver of a car that allegedly left the highway and crashed into a tree on the north coast on Good Friday has been charged with five offences, including driving under the influence of alcohol and dangerous driving causing grievous bodily harm.

Police will allege the Holden Commodore was travelling south on the Pacific Highway at Kundabung, south of Kempsey, on March 25 when it left the road and clipped a guardrail, before crossing the highway and ploughing into a tree.

A 41-year-old man was critically injured in the smash.

He has since been released from hospital.

The 35-year-old male driver and three passengers - two men aged 37 and 61, and a 30-year-old woman - were taken to hospital with serious injuries.

Following an investigation the driver was charged on Monday with three counts of dangerous driving causing grievous bodily harm, and one count each of negligent driving causing grievous bodily harm and driving under the influence of alcohol.

The man's driver's licence was suspended and he was granted conditional bail to appear at Port Macquarie Local Court on April 27.
