Last year 45 Kiwis became overnight millionaires via Lotto wins.
There was a $16.2 million win in April.
The Auckland winner told the Herald after the win: "This is completely life-changing for us. We're going to invest most, help out friends and family and give to charity. Oh, and we'll do some travel too… actually we could probably go to the Rugby World Cup now."
In January, the North Island town of Feilding was abuzz after a $10 million ticket was sold there. It was the 10th big win from tickets sold at the Feilding Video Centre.
"We trade on the fact we are Feilding's lucky Lotto store," Lotto operator Ann Heap said.
In 2016, one young couple from Hibiscus Coast secured a $44m windfall after striking Powerball.
One of the winners only found out about the new riches after checking the ticket during a "smoko break".
