Hers wasn't the only win in Whanganui over the last few days, with a Lotto First Division ticket worth $250,000 sold at New World Whanganui.
As of Tuesday afternoon, the winner was yet to come forward.
Powerball was not struck on Saturday and has rolled over to Wednesday night when the jackpot will be $14 million.
In July, a ticket purchased at Countdown on Victoria Ave scooped an $18,064 prize after winning second division alongside 18 other players.
That same month, an Instant Kiwi player in Bulls won $100,000.
