He said the device was left on an empty section at the corner of The Tool Shed.
The shop owner said police had shown him a photo of the can, which he said was “similar to a large V can” that had fluid inside.
The can also had wires coming out and an electrical device strapped to the side.
He told NZME “it’s gutting” that this incident has such an impact on the area, including his customers who cannot come and go from his business as a result.
While disposal experts continued to work away, a small crowd has gathered at the Aldwins Rd end of the cordon, with local shop workers awaiting the all-clear to return to their stores.
The Tool Shed staff were seen among those evacuated at the end of the road block, however they will not comment further at this time.
