The man walked into the Challenge petrol station on Kent St, Picton around 4:20pm on Thursday.
He took an amount of cash and left on foot. He was later seen getting into the driver's seat of a single-cab black Holden Commodore ute.
Police located and arrested a man believed to be behind the robbery overnight. He is expected to appear in Blenheim District Court on Friday charged with aggravated robbery.
