Another Countdown store has been damaged by what the company believes is a non-accidental fire.
The store at Botany, east Auckland, was evacuated when a small fire caused some smoke.
The company said it did does not think the fire was accidental, and it was cooperating with a police investigation.
The store was to reopen early afternoon, the company said.
Police are treating the fire as suspicious.
Six weeks ago a suspicious fire at a west Auckland Countdown forced the evacuation of an entire mall.
