"We don't know how helpful it will be, but it's definitely better than nothing," Thakkar said.
The group has also asked Hamilton East Labour MP Jamie Strange to get the Government to supply every store with a cigarette vending machine and increase community patrols.
Hamilton East National MP David Bennett has been working with the dairy owners and said he believed fog cannons were achievable in the short-term given there was increased funding available. He was unsure whether vending machines would stop dairy robberies because the thieves could find other items such as cash.
Bennett expected every retailer on the list would be assessed for the fog cannons, but said they had to meet a certain criteria to be eligible, which included looking at how many robberies there had been.
"There will be a reasonable number that meet that criteria."
Eligible shops have to pay just $250 for a $4000 fog cannon with the Government picking up the rest of the bill.
Under the revised Labour scheme, there was now funding available for 420 businesses and so far only 52 businesses have had the fog cannons installed. The trial initially targeted 100 of the most vulnerable stores.
Police confirmed last week that every district across the country including the Waikato had shops which met the criteria and which were being approached for subsidised fog cannons.
