The man came in through the back door about 7.20am on March 4.
One staff member closed the back door and threw items of food at the man while the other tried to hit him with a display stand.
The offender was not able to get into the till or the locked cigarette cupboard. He smashed a computer screen before running away empty-handed.
The man ran off through alleys between Tenth Ave and Eleventh Ave heading towards the city and was last seen running down Eleventh Ave near the Mad Butcher.
The man was skinny, wearing a black balaclava, a large baggy camouflage jacket with a hood, black combat boots and blue skinny jeans.
Mr Bell was hopeful the segment would see results as people always wanted to help solve serious crimes.
"There's good security footage which is always good for us because it gives our viewers a chance to play detective," Mr Bell said.
Mr Morgan said if anyone had any information, to call police on (07) 577 4300.
Police Ten 7 will screen on TV2 at 7.30pm on Thursday.
