"People are always saying, 'Hi Nana' whenever I'm in or around the shop. I do know quite a few out-of-towners," Wells said, "and it's nice getting to know them and the locals."
When asked if people knew her real identity, Wells paused before she said: "I doubt most do."
Four Square Waipū owner Jodie Ansell said people loved their daily interactions with their "jack of all trades" Nana.
"She keeps thinking she is going to retire but Nana is so important to everyone here. We'd be lost without her."
Although born in Auckland, she answered the call to her "true home" decades ago. Wells' roots burrow deep into the area's history as her McLean grandparents were one of Waipū's original founding families. She proudly described how photos of family members were displayed in the local museum.
Originally a nursing home caregiver and a shoe-maker, Wells opted to work at the Four Square ahead of retirement "just for something to do" and has never looked back, she said.
"It's really friendly here. I love being a part of the community and getting to help elderly customers and meet all sorts of nice people."
When she's not busy stocking the chilled drinks or assisting elderly shoppers with their groceries, Wells and her husband plus their grown kids can be found on the sidelines of local rugby matches cheering on the home side.
"We are big supporters of the local rugby club here. We love our weekends spent watching the games," Wells said. "I don't think I'd want to live anywhere else."
