Coming in second is a Christchurch Lotto store, with Pak N Save Riccarton having sold 30 First Division winning tickets. This includes a $22.5 million winning Big Wednesday First Division ticket sold in September 2013.
Rounding out the country's top five 'luckiest' stores are Richmond Night N Day in Nelson with 29 First Division wins, Coastlands Lotto in Paraparaumu with 28 First Division wins and Hornby Mall Lotto in Christchurch with 25 First Division wins.
Last year, Bayfair Lotto retained its rank as the country's fifth luckiest outlet - a title it held since 2012.
Kirsten Robinson, Corporate Communications Advisor at Lotto NZ, said while the top five stores had a reputation as being some of the 'luckiest' in the country, there was no predicting where Powerball would be won next.
"Powerball can be won by anyone, anywhere, at any time - it's all part of the fun! The only thing we can guarantee is that you can't win if you don't have a ticket," she said.
In February this year a Tauranga family won $7.1 million with luckyk numbers that had been in the wider family for over 20 years. But, the winners only started playing these numbers weeks before their big win.
Lotto players can buy a ticket for Saturday's $22 million Lotto Powerball draw from any Lotto retailer or online at MyLotto.co.nz.
