"We really excited, really happy," Mrs Patel said.
"People are coming into the shop and phoning us to talk about it."
She and her husband had had a celebration of their own when they heard the news, she added, Mr Patel saying the win would be good for the business and for the community.
Nimesh Shah, who owns the business, was equally delighted.
"The place is buzzing. Everyone is talking about it," he said.
He bought the business in 2010, but only gained the Lotto agency in 2012 or 2013, and this was the first big win, he added.
The other half of the Division I pool, worth $500,000, went to a ticket bought in Taupō.
