Sang said it was "amazing" and "unbelievable" as this was the family store's biggest ticket win and even got their children excited.
Sang said the news was also great for the city which hadn't had a big Powerball win in a long time. Her morning had been spent excitedly waiting for the winner to walk through the doors and scan their ticket.
Although many people have checked their tickets, the winner was yet to claim their title.
She said she wasn't sure how, but they would celebrate the exciting news tonight.
Meanwhile, a My Lotto ticket sold in Rotorua won Lotto Second Division last night worth $12,933.
