Lotto Powerball $50m jackpot: 'Psychic' gives surprising prediction on result

New Zealand's largest-ever Lotto draw will take place on Saturday, and the money has got to be won.

The jackpot prize of a whopping $50 million is up for grabs, and the big question is: will one winner take it all?

The Lotto draw is 100 percent random and no one can accurately predict the outcome. But Jane Brebner at NZ Psychic says while it's rare anyone - even a self-described psychic - could accurately predict the numbers, she feels the jackpot will sway towards one winner.

"For obvious reasons, I'd prefer that this ridiculous amount of money goes to multiple winners.

"[However], I predict that there will be one winner who emerges to scoop the pool."

Some Lotto players prefer to choose numbers randomly, others stick to the same numbers. Brebner says that there's no specific method that has a greater chance of winning, but suggests that positive thinking - and using birth dates and other personal numbers - could give players an edge.

"The law of attraction could be at play. If you constantly say 'I never win', then you probably won't.

"The opposite of playing your favourites all the time, could have just as much effect."

Encouraging people to "play responsibly" and "know their limits"', Lotto New Zealand said that like all lotteries, games are based on a large number of people paying a small amount of money in the hope they'll win a big prize. 

Psychic or not, Brebner agrees that Lotto is a game - and it's a gamble.

"The important thing is that a 'flutter' is a bit of fun: you should never gamble more than you're prepared to lose. 

"I always fancy 14," she added.

Russell Millar, a statistician at the University of Auckland, told Newshub that because it's a must-win, predicting the odds is difficult - but said people have a "one in 7 million" chance of winning the jackpot.

If a single player wins the first division jackpot, they'll take home $50 million. If there's no winner, the draw will roll down to division two.

With a guaranteed payout on Saturday, Lotto New Zealand expects ticket sales to soar to over 2 million. Tickets are open until 7:30pm on Saturday and can be bought in-store or online.
