Lotto says a third winner from Saturday night's $50 million must-be-won draw has now come forward to claim their prize.
The ticket was sold at New World Hastings, and comes after two winners came forward on Sunday.
Lotto said they expect to have more to share in the coming days.
"Our advice to anyone who had a ticket in Saturday night's $50 million draw - especially those who bought their ticket in Auckland or are Auckland-based - is to check their ticket as soon as possible," Lotto said in a statement.
"Anyone who has checked their ticket and is a Powerball winner from the weekend should give our customer service line a call to be put in touch with our winner's team who will support them from there."
The winning tickets so far:
Seven tickets split the $50m Powerball prize after the jackpot rolled down to Powerball second division.
Each ticket will take home a total prize of $7,180,041, made up of $7,155,649 million from Powerball first and second division and $24,392 from Lotto second division.
The winning numbers were: 22, 35, 10, 30, 21, and 37. The bonus ball was 5 and the Powerball was 2. The winning tickets were sold at:
"It's amazing that Powerball rolled down to Second Division and was shared between seven players - it's fantastic to see more of our lucky players get to experience what it's like to win," Lotto NZ CEO Jason Delamore said last night.
"This is going to be life-changing, and not only for the lucky winner themselves, as we know winning big has a huge ripple effect. Most of our big winners share their prize with others, including family, friends, communities, and charities. This means that the win makes a huge difference to more than just one person."
