The Kiwi Liquor store in Pukekohe has been robbed by a man wielding a knife.
The man entered the store on Manukau Rd about 2:45pm on Friday and took off down Harris Rd with stolen cash.
Police are seeking witnesses.
The man was wearing a dark hoodie with the hood up and had a light bandana over his face. The attendant wasn't injured.
Also on Friday police separately made a second arrest in relation to the aggravated robbery of the Irvine St dairy in Hamilton on November 27, during which the owner was assaulted.

Police earlier arrested a 13-year-old man in relation to this robbery.
