The six most frequently drawn winning numbers since 1987 are 1, 7, 12, 13, 18 and 21.
Combine that with a Powerball of 2, which has been drawn 111 times, and you will have the numbers that are historically proven to be the most successful.
Lotto spokeswoman Emilia Mazur says there's a "real buzz" around the massive jackpot up for grabs.
"We see a lot more people coming into the game when the jackpot is high and sales have been very strong."
Only one Powerball player has ever won more than the $30 million on offer tonight, when a lucky ticket scored its owner $33 million in September 2013.
Statistics provided to the Herald by Lotto show 70 per cent of players choose random numbers, rather than pick them themselves.
Eighteen people have won $1 million or more this year, with five of those coming from Auckland. Tiny Wainuiomata in Lower Hutt - population 16,786 - can lay claim to two million-dollar prizes so far in 2016.
What do those winners spend their newfound cash on? According to Lotto, half jetted off on overseas holidays, including family trips to Disneyland and a 70-day around-the-world cruise.
Just under half decided property was an area to allocate some of their funds, with 40 per cent paying off their mortgage or buying a new home.
Another 40 per cent splashed out on new cars, motorbikes and boats.
A recent winner of $15 million in Powerball said it was important to stay calm despite the excitement that a big win creates.
"Surround yourself with people you trust and get their advice, whether that's your partner, kids, best friend or a financial adviser.
"Having someone you can throw ideas around with is really valuable."
