A man is expected to face a NSW court after being charged with a one-punch assault that left his alleged victim in hospital with a broken nose and jaw.

A 23-year-old man was charged on Wednesday over the attack, which occurred in Kariong on Christmas Day, police allege.

The 27-year-old victim suffered multiple facial injuries and was taken to Gosford Hospital.

His alleged attacker was charged with reckless grievous bodily harm and is expected to face Newcastle Local Court on Thursday.
