Mr Taylor confirmed police would prosecute the 25-year-old man behind the wheel.
"It looks like he was speeding down a side road, across the intersection and into Pak'n Save," he said.
"[Investigators] did not outline what [the charge] will be but it will be in the nature of careless use of a motor vehicle."
In the absence of a manager in store, Pak'n Save would not comment on the incident.
Foodstuffs spokeswoman Antoinette Laird said though there were staff in the supermarket when the crash happened, fortunately no one was near the window.
She said there was significant damage to the store front, which was currently covered with a tarpaulin, but it would be business as usual.
"It might not look very pretty but the store's open and functioning," Ms Laird said. "People need their groceries."
