The top tip that could help you win that $50 million Powerball jackpot!

An insane $50 million is up for grabs TONIGHT, which will be the biggest Lotto draw in New Zealand's history.

And luckily for you, we've found out just how you can win it:

WHAT POWERBALL NUMBER TO PICK

According to Powerball Lotto data, one number has proved luckier than others.

In the history of Lotto in New Zealand, the number "2" has topped the tower more than 94 times.

It's followed by "5", which has been drawn 70 times and "7", which has been drawn 67 times.

But if you want to actually pocket that $50 mill, then avoid Powerball numbers "10", which scores as the worst, having been only drawn 56 times.

And for the full line, here are the most common New Zealand Powerball winning numbers: 19, 15, 1, 35, 22, 2, 5, 7, 6, 4.

FOLLOW THIS ADVICE FROM A WINNER

Florida man, Richard Lustig, who has won several grand prizes in Lotto, has written a book called Learn How to Increase your Chances of Winning the Lottery.

His advice to everyone rushing out for tonight's grand prize is simple: Don't buy quick picks, where a computer picked numbers for you.

"I play my own numbers, I play them regularly and I never miss a draw and again that's what increases your chances," he said.

"Seventy percent of our players choose randomly."

Good luck and hopefully you wake up a millionaire!
