Tonight's Powerball haul is the last big Lotto win of the year.
Over the past decade, 374 Kiwis have become millionaires after winning the jackpot, and collectively Lotto players have won almost $4 billion.
The biggest win came in 2016 when a young couple from the Hibiscus Coast, who had been "busting their guts" to buy their first home, stopped by a dairy to get their regular ticket.
But that weekend, they won the biggest ever Lotto prize - $44m.
"As soon as I saw I had all the numbers on one line I just yelled 'holy ****!' - my boss thought I'd chopped my arm off with a saw," the man told the Herald at the time.
And in 2013, a lucky punter scooped what was then the biggest amount won by a single player in Lotto NZ history, a whopping $33m. The winner bought their ticket at One Step Ahead in Ponsonby, Auckland, and played using their own numbers. They played every week before the big win.
And last year, the winner of a $20.2m jackpot kept their lucky ticket unwittingly tucked in their wallet for days before they checked if they'd won.
"It was fun to dream for a while.
"Eventually I went back to the store to check my ticket, I had a bit of a knot in my stomach when I handed it over — I guess I was hoping it could be me.
"The Lotto lady handed me a piece of paper that said '$20.2 million' on it – it was a huge sense of relief."
