A man has been arrested on the NSW Central Coast after a police car was rammed into during an alleged domestic violence dispute, sparking a manhunt.

Officers were called to a home on Goorama Avenue in San Remo at 5am today after reports that a man armed with a knife was standing in the middle of the road.

Police shot a Taser at the man to arrest him, but he got into his car and drove towards officers, ramming into their vehicle.

At least one shot was fired towards the man as he drove away from the scene in a grey Mitsubishi station wagon, with the number plate EVM91J.

A manhunt followed throughout San Remo, Budgewoi and Charmhaven to locate him.

A man was arrested around 7.30am in Gorokan.

NSW Police confirmed a woman was taken from the home in San Remo to hospital for assessment.

Her condition is not yet known.
