Most of the stolen items were recovered.
A woman was arrested and charged with burglary.
"These people take advantage of unattended and insecure entranceways and the fact that the lawful occupants are usually in other areas of the workplace, which allows them to go undetected."
Mr Burne also urged people to keep power tools secured in the wake of another incident.
There had been a string of tool thefts over the past few months and a building site off Edmundson St was the most recent target after the site was broken into.
A nail gun, power planer, a Makita Multitool and a Hitachi drill with a battery and charger were stolen.
Thieves also targeted tools which had been left in a utility vehicle parked up in Wright St, Ahuriri.
While those incidents were still being investigated the value of high level CCTV surveillance cameras had resulted in police resolving two out of three reports of theft from Prebensen Drive retail outlets.
Police had also solved three of four shoplifting incidents reported at various retail outlets in Ahuriri with the offenders "facing the judiciary as a result".
