Lotto winnings from tickets sold at the Reefton store throughout its history total in the "tens of millions''.
Previous wins include $10.6 million in 2011, $10.6 million in Big Wednesday, and $6.1 million in 2008 by local resident Harry Wilson.
Mr Wilson said at the time he told one person about his win and within about 10 minutes the whole town knew about it.
Lotto said today the Reefton store had, over the years, sold seven division one winners, a Big Wednesday first division winner and a Winning Wheel top prize.
