New World Whakatane keeps selling winning Lotto tickets with the latest one worth $500,000.
The First Division prize won on Saturday comes a month after the supermarket sold a $1 million ticket and $15,000 in Lotto's "Make Summer Last Forever" promotion.
New World Whakatane owner Dave Trubshoe said there was usually a lot of buzz in the store in the days following a major win.
"Cherie and Robyn have run the Lotto for years, they're legends around town. I always give Cherie a hassle because she never sells me the winning ticket," Mr Trubshoe said.
"They're the face of Lotto in Whakatane and have made a lot of people of people very, very happy. They know all our customers and I know they get a special kick out of it when someone wins."
