Lotto riches: Have you just won $20m?

The potentially lucky Lotto numbers for securing an overnight $20 million windfall are in.

The numbers for the massive Lotto Powerball draw are: 30, 40, 20, 18, 4 and 10.

The bonus number is 25, and the Powerball is 7.

Powerball was rolled over but one person won $1m in Division 1.

Lotto's jackpot prize ticked over into the mammoth multi-millions after the $19.3m prize was not struck on Saturday night.

Four people came close to winning that prize - the biggest since before the level 4 Covid lockdown - but instead split Division One's $1m, collecting $250,000 each.

Before Saturday's draw, Marie Winfield from Lotto said it was the highest jackpot since the $50m "Must Be Won" draw on February 29.

That draw saw two lucky winners from Auckland and Hawke's Bay each take home $25.1 million each.

The $50m figure is the cap-limit Powerball is allowed to reach in New Zealand.

A staggering 2000 tickets were being sold per minute in the hours leading up to the 8pm draw.

By 3.30pm, more than 1.9m tickets had been sold. And Lotto NZ said it expected the number of tickets to top a record-breaking 2.5m mark. The most tickets previously sold was 2.4m.

By 6pm the number of tickets sold had topped the 2.3m mark.

Winfield said that before the nationwide lockdown 75 per cent of sales were from stores and only 25 per cent were through MyLotto or the Lotto NZ App.

Now 39 per cent of sales are purchased online, while 61 per cent are still bought in store.

The biggest single win in Lotto's history was the $44m won via a ticket sold at the Dairy Flat Food Mart in North Auckland in November 2016.

Ahead of the draw Lotto NZ released advice from those lucky winners for future newly minted Kiwi Lotto players.

"First of all, don't have a heart attack! That's the most important thing to remember," laughed the one of the winners.

"But seriously, my best piece of advice is to remember to eat and sleep in the first two weeks. It's the little things like that that are easy to forget in the early days after a big win."
