The jewellery store was left destroyed and cabinets emptied out by the group of masked thieves, who struck at 5.20pm.
The store had its door and cabinets smashed with glass strewn across the floor.
The owner's son, Navneet Shee, was inside the store's office when his staff ran towards him yelling "they are here".
"I went outside to look," Shee told the Herald.
"Five masked men armed with hammers and wearing gloves broke everything, all cabinets, they took most of our new stock which we had put out for Diwali."
Shee said the incident happened early evening, and when his security guard tried to stop the offenders he was attacked.
"He went to the hospital. Neighbour shop's owner also tried to stop them.
"But they had two getaway cars."
Shee said they were still in shock.
"All business owners around New Zealand are scared to even open their stores ... and that's not a safe way to live. Government needs to take action."
Police confirmed today inquiries were ongoing to find the offenders.
