A 30-year-old man has been arrested over the robbery of a Porirua store on Christmas Eve.
Police said the man entered the shop on Mungavin Avenue around 2pm on Sunday and punched the store manager, causing him to fall to the ground.
He then fled the store with cash.
The manager suffered moderate injuries to his face in the attack.
Detective Senior Sergeant Ian Martin said information from the public helped lead to the arrest.
"We really appreciate those people who have come forward with information, which has helped lead to a quick arrest."
The man is due to appear in the Porirua District Court today, on a robbery charge.
