A man has been shot dead at Gosford on the New South Wales Central Coast.

Emergency services rushed to Gertrude Street in Gosford in response to a triple-0 call just before 2:00pm (AEST).

It is believed a man was shot in the head and stomach, but police will only confirm that an operation is underway on the street.

The Ambulance Service waited for more than two hours before reaching the victim.

A short time ago a spokeswoman told the ABC that a patient has now been found dead with gunshot wounds.

Police will not say whether a crime scene has been established, but the street has been cordoned.
