Four other people shared Lotto Division One - each winning $200,000 because they didn't have the Powerball number.
The numbers for Saturday night were: 1, 4, 6, 8, 11, 19.
The bonus ball was 34 and the Powerball was 1.
All Lotto tickets are being bought online during the level four lockdown.
A Hawke's Bay mother collecting $25.1 million last month. She was one of two Powerball First Division winners for the record $50 million jackpot and bought her ticket from Countdown Manukau City Mall.
Days after her win the woman said she was still in shock.
"It was a total surprise - you never think it will be you. I still can't believe it."
The Hawke's Bay woman, who wishes to remain anonymous, bought the Triple Dip on a visit to Auckland, but didn't think she'd won.
"I saw that one of the winning tickets had been bought at the same store where I got mine - but never in a million years did I think it would be me!"
She said there's been a 'few sleepless nights' waiting for the prize to be officially confirmed by Lotto NZ Head Office.
"I've been keeping my ticket in my phone case and under my pillow at night – not that much sleeping has been happening. I've mostly been scouring the internet for my dream car," laughed the woman.
