"The blatancy of stealing large amounts of items during the day while the shops are open is concerning, as is pushing staff out of the way to run off with items. It's very much a concern for the police."
Quality jackets, surf wear and sunglasses were among the goods stolen from stores such as Kathmandu on Elizabeth St and in Bayfair plus North Beach in Fraser Cove.
Mr Turner declined to say how much the jackets from the July 3 theft were worth but said the business had suffered a substantial loss.
"It is very brazen."
Mr Turner said in addition to the shoplifting, groups of people were committing burglaries after-hours and using stolen cars to either ram raid a store or flee with stolen property.
Police were keeping an open mind to any connections between the groups, he said.
"What is a common denominator between all of these is there will be people out there who are prepared to receive the stolen property and forward it on. That's the key to solving them - the community identifying those persons trading in stolen property."
Mr Turner said it was not only retailers who lost out, but the wider public who have to pay higher prices for goods to cover the loss created by the thefts.
"It affects all of us."
Retail NZ public affairs general manager Greg Harford said retail crime was getting increasingly more aggressive and violent.
"The biggest concern is it's becoming more brazen. People are doing this in broad daylight and acting like they are going to get away with it," he said.
"Everyone deserves to go to work and be safe."
Mr Harford said retail staff should not put themselves in harm's way, but they should keep a clear line of vision on people acting suspiciously and call the police.
Bayfair manager Steve Ellingford said the thefts were concerning but said people should avoid putting themselves at risk because people's welfare was "by far more important than a product on a rack".
Representatives from Kathmandu and Northbeach could not be reached for comment.
