The winning Strike ticket was sold at Limbrick Street Maxi Mart in Palmerston North.
Tonight's win makes it the fifth time Powerball has been struck in September alone, after two outrageously lucky players in Auckland and Christchurch took home a total of $24.5 million between them.
Two further winners will also be celebrating tonight, after winning $333,333 each with Lotto First Division.
The winning Lotto tickets were sold on MyLotto to players from Marlborough and Christchurch.
Two lucky players scooped up $500,000 each in Lotto First Division prize a week ago, splitting a $1m dollar prize.
The two winning tickets that shared the $1m prize were sold at Countdown Westgate in Auckland and Napier City Pak 'n Save in Napier.
And one Christchurch man might well be driving his dream car around the city now, after planning to spend his whopping $10.5 Lotto Powerball win on a Lamborghini.
He said he was overwhelmed with his "unbelievable" win but adamant about what was at the top of his shopping list.
"I've always wanted one [a Lamborghini] so why not now?"
Still reeling from the life-changing win, he said he would celebrate with a "cook-up" at home with his family and a trip somewhere in the South Island where he could relax and plan his new future.
