The winning ticket was purchased from Hylite Dairy, in Auckland's Grey Lynn.
Tonight's winner is 10th Powerball winner already this year and comes just three weeks after a MyLotto player from Auckland won $14.25 million with Powerball First Division.
The winner won big while playing her own lucky numbers – a combination of family birthdays, milestones and special events.
Two other Lotto players from Auckland and Wellington will also be celebrating after each winning $333,333 with Lotto First Division tonight. The winning Lotto tickets were sold on MyLotto.
