"I was thrilled, in part for the Lotto team down there. They'll be so excited. They always want to sell winners.
"Our main Lotto lady, Gloria, she just wants people to win. It's more than a job for her."
The $2m win was the only First Division winning ticket the store had sold and Mr McGregor was glad their ticket would change someone's life.
"It's fantastic that it's happened for someone out there. It's a good win, a life-changing win.
"People who come in and buy Lotto buy into the dream and the fact the dream has come true for someone is very exciting."
Mr McGregor hoped the win would go to a local, knowing the store had a lot of regulars.
Pak'n Save Papamoa Lotto supervisor Gloria Goebel said the staff were excited and called her as soon as they heard the news.
"We've all been hoping to get a really big win at our store and we're really happy for the winner, whoever it may be.
"I always said it will happen, it will happen soon."
It was the biggest win she had been a part of in her time working with Lotto and she was happy for the recipient.
She hoped they would come into the store to claim their win so the staff could share in their good luck and dream come true.
The Bay's Lotto luck did not end there, with a Waihi man taking home $175,000 with Lotto's Winning Wheel on Saturday's live Lotto draw.
Lance was looking forward to life in the fast lane after the win.
Summer beachgoers to Waihi may have recognised Lance from his long-term employment at Gasoline Alley.
"He is a big advocate for Waihi and loves the outdoor recreation the area has to offer, including surfing and walking," the announcement from Lotto NZ said.
As part of the Winning Wheel prize package, Lance and his mum Marie enjoyed a weekend of luxury at the Sofitel Hotel in Auckland's Viaduct Harbour. They were also treated to a shopping spree with a stylist and star treatment on the Lotto draw.
