Hawke's Bay Police are appealing for information following a robbery at the Onekawa shops on Maadi Road just after 8pm yesterday.
Police said a male entered the Onekawa dairy and confronted the sole woman occupant threatening her with a small knife and demanding cash and cigarettes.
He put the items into a satchel he was carrying and then made the victim lie on the ground and tied her hands behind her back before running from the dairy.
The male is described as being dark skinned and wearing dark shorts, a dark hoody with the hood up and had his face covered with light coloured material like a hanky.
Police believe there is a possibility the offender may have been watching the dairy for some time before entering.
