Lotto's website was struggling to keep up with demand as punters checked their tickets.
$42m prize up for grabs
Punters came out in droves to buy last-minute tickets ahead of tonight's draw, with queues snaking through the door of one Auckland dairy.
With more than one million tickets sold ahead of tonight's draw, you might assume your chances of hitting the jackpot become slimmer with every ticket sale.
But, as University of Otago statistician Dr Matthew Parry earlier told the Herald, you'd be wrong to think so.
"The probability of winning doesn't change, that's always fixed no matter how many people are playing in the lottery," he said.
"It just depends on the numbers that come out [but the] more people play, more people are likely to win so, therefore, your payout slightly gets smaller."
But with your chances of winning Powerball are still slim - at around one in 38 million.
"We wish you all the best for the future, and hope you'll look back on the day you found out you were a winner as one of the happiest days of your life."
But tomorrow is not the day to start spending newfound millions, Lotto winners are warned.
Craig Offwood from ANZ's Private Bank team told The Herald the moments after striking gold were "definitely not" the time to make any rash decisions.
"From our experience, it's clear what winners do with their prize has a huge impact on the rest of their lives."
Seeking professional advice was an important step in the days after people came into a significant amount of money, Offwood said.
"Many people will inherit money at some point in their life, and although the sum may be less than a Lotto jackpot, the challenge is always the same," he said.
"Over the years, we have seen some great success stories. Equally, there have been some cases where they have squandered their jackpot.
"After failing to heed advice, they have gone on a spending spree with the unfortunate belief the winnings would last forever.
"The last thing you want is to find yourself with no money in 10 years' time."
However they'll likely have enough to splurge on a set of bagpipes, a gastric bypass, Prada shoes, or whatever takes their fancy, in the vein of past Lotto winners.
According the Winners' Book, most Powerball winners splashed on a new house, paid off mortgages, helped family members travelled overseas and donated to charity.
But for others, professional tattoos, face lifts, fertility treatment and even a buffalo-hunting trip fit the bill.
Two lucky Powerball winners won $19.1m each in October last year, sharing the same ticket numbers for a $38m draw.
Four months on, one of the pair has just bought their dream house, even if she still drives the same $2000 car from before her days as a multi-millionaire.
"We've always dreamt of owning our own home and now it's a reality – though it's still quite hard to believe."
Both winners of the $38m draw told the future Powerball winner to keep things simple.
"My top piece of advice is to take your time, make sure you have a solid plan in place, and you have a financial adviser that you're comfortable with," one said.
