The scratchie was a $10 crossword, and netted its holder $200,000.
Patel said the man who claimed it was a local man.
"He's a nice guy, he deserved it, he called his mum straight away."
More good news followed hot on its heels.
A ticket sold from the store was one of five to win $200,000 in Lotto First Division in last Wednesday's draw.
Patel said no one had come into the store to claim the prize, and he did not know if it had been claimed elsewhere or not.
He hoped it was a local who had won.
Asked how it felt to have the double win, Patel said: "It feels great."
It was good for business, he added.
He said some customers coming into the store had been calling them lucky.
"Especially two in a row, that doesn't really happen that much," Patel said.
He said they always tell their regular customers to come and check their tickets.
Two trophies acknowledging the two prizes had arrived and were on display behind the counter.
Bhupen Patel has told the store's owners about the back to back prizes. "They were happy."
Sunnyside Foodmarket have struck the big one before - selling a ticket which won $5.5 million in November 2016.
That prize was claimed by a Whangārei man.
"We don't want to rush into anything, so we're planning on investing most of it for a year or so. But we do want to pay off the mortgage and help the kids out - we might even splash out on a holiday next year," the winner said at the time.
"And I'll be retiring early now, that's for sure."
A Lotto spokesperson did not respond by edition time to confirm if the winning ticket from the March 27 draw sold at Sunnyside Foodmarket, has been claimed.
The other tickets were sold at Lincoln Rd Dairy in Auckland, Glen Innes Dairy and Lotto Outlet in Auckland, Brookfield Foodmart and Lotto in Tauranga and New World Motueka.
