Mandeer estimated those in the group ranged in age from 18 to 25 years.
He said the well-rehearsed group didn't say much, barking orders at himself and shop manager Gagandip Singh to get into the back storeroom and to open the till.
"They just came in and come on to you. Two start stealing and two take control of the people."
He said it was a terrifying minute, and one that left him thinking it could be his last.
"When they got behind the counter it [the machete] could have hit me. Then when they made me go into the back I thought it could be the end."
He said it was a similar story in September when a group of four masked men stormed into the store holding Singh's mother at knifepoint and his father at gunpoint.
Security cameras captured the vicious raid where Jaswinder Kaur has the blade of a machete menacingly held across her throat and her husband Ravinder Singh a gun aimed at his head.
The group targeted the cigarette cupboard and till, with the money box wrenched out of the cabinet.
The robbers proceeded to stuff a bag and pockets with cash and cigarettes before fleeing.
Detective Senior Sergeant Albie Alexander, of Counties Manukau Police, said police were investigating the latest incident. The investigation includes reviewing forensic evidence and CCTV footage.
"At this stage, we do not believe the same offenders are responsible for both incidents (5 Jan and 19 Sept) and there is no indication to suggest the offenders are linked.''
Alexander called out the offenders and said officers would utilise all resources available to hold those responsible to account.
"Those committing these crimes have no respect for the property or victims they target.''
Mandeer said fortunately in both incidents those in charge of the shop were not injured but the trauma and loss of thousands of dollars worth of stock and cash was making them think twice about selling cigarettes.
"We would stop selling smokes if this keeps happening," he said.
