Police have appealed to the public for dashcam footage in the Morpeth area between 4.50am and 5.30pm.

In a statement police said three men entered a grocery store on Swan Street, Morpeth, and approached the tills.

The group began removing cash from the drawers before the employee, a 47-year-old man, approached the trio and challenged them.

One of the men struck the employee with an unknown object. All three fled the scene a short time later in a white sedan.

The injured man suffered a wound to his abdomen and was treated by NSW Ambulance paramedics before being taken to John Hunter Hospital for treatment.

Officers from Port Stephens-Hunter Police District attended and established a crime scene.
