Lotto's $20 million Powerball: Are you New Zealand's newest multi-millionaire?

One lucky Kiwi could be a whopping $20 million richer after tonight's Lotto draw.

Wednesday night's numbers were 2, 3, 6, 15, 31 and 40. The Powerball was 1 and the Bonus Ball was 30.

The jackpot jumped after Saturday's Powerball wasn't struck. A Bay of Plenty player did have a six-figure win, pocketing $200,000 after winning Strike Four. 

Last month, a winner who won an incredible $17.1 million finally came forward to collect their cash.

Their ticket was purchased from the Market Store in the small Canterbury town of Twizel on December 28.

"I wasn't in a rush to claim the prize - and I needed some time to process things," the unnamed winner said.

"It's all been very surreal."

The winner said the win would change their lives.

"What an amazing way to start the year," they added, excited they now have the chance to travel more while also donating to a number of charities.

Lotto said the winner also wants to use their winnings to pay off the mortgages of close family members.
