In the past 33 years, 943 lucky winners have become millionaires with Lotto NZ games.
The largest Powerball win was in late 2016, where a couple in Auckland's Hibiscus Coast scored themselves a giant $44.1m.
The 2016 winning ticket was sold at Dairy Flat Food Mart and Liquor.
Earlier this year, two lucky winners from Auckland and Hawke's Bay shared a historic $50 million Must Be Won jackpot taking home $25.1m each.
Between August 1987 and June 2019 a total $4.6 billion has been given to charities and community groups.
There have been some big winners over the years.
In September 2013, a $33.1m ticket was sold at One Step Ahead in Auckland, and a $30.2m winning ticket was sold at Taupō's Richmond Superette in September 2017.
Of the five largest Powerball wins by an individual, three of the tickets were sold at Auckland stores.
Overall, Powerball first division has been won 191 times since the game began in 2001, with the number 2 the most commonly drawn Powerball number.
The northernmost Powerball winner was a player from Taipa in the Far North, who won $5m in May 2019.
The southernmost Powerball winner was a player from Invercargill, who won $20m in 2013.
Marie Winfield, Lotto's head of communications and corporate social responsibility, said the most common thing New Zealanders say they will spend a big win on is buying a house or paying off their mortgage.
"Lotto NZ turns 33 today and we're thrilled to be able to celebrate with a jaw-dropping $30 million Powerball jackpot tonight," Winfield said on Saturday morning.
Outlets were prepared for a "busy day" ahead of the big draw.
Pervious winners are known to keep winning tickets in weird and wonderful places including underneath their pillow while they sleep, tucked inside the cover of an obscure DVD or even inside a piano stool and taping the ticket to their body.
