This win brings Greerton Lotto's First Division total to 20 - just one win behind Tauranga's luckiest store, Bayfair Lotto.
The shop also sold a winning ticket on February 14 worth $4.5 million, to a retired couple who celebrated their sudden multimillionaire status with a cold beer.
That success was followed soon after by a $2 million Lotto win from Pak'nSave Papamoa on March 21.
