It is the second time inside two months that the store (Price Cutter) has been the target of an aggravated robbery. In April an offender fled with cigarettes and cash after threatening a shopkeeper with a mallet.
This incident is the latest in a spate of robberies around Hawke's Bay within the past few months.
Earlier this week, a screwdriver was used to threaten staff at a dairy in Frederick St Hastings.
On May 20, two men with a hammer stormed into the Grays Rd Convenient Store and Takeaway, one offender smashing the cabinet and the computer screen on the counter, while the other went to the cigarette cabinet.
On the same day, police were also called to a robbery at Mobil Havelock North service station in April.
Lone attendant was confronted by a man said to be brandishing a knife and forced to hand over cash.
The continued aggravated robberies at dairies in Hawke's Bay have pushed the region's tally to 39 for this year (not including today's incident).
