Mrs McKenzie continued the legacy of the shop formerly known as Awamoa Clothing, then managed by Debbie Shields, who ran the store for over 20 years before the original owner, Carol Scott.
Tracey Blackler, from Southland, will take over ownership of the business from April 1, under the new name Awamoa Boutique.
Mrs McKenzie said it had been an enjoyable six years and she would miss the "good relationships" she had built with her "great customers and clients."
"I’m going to miss the constant people coming in.
"As they mature and grow, you have young girls coming in and then, next thing, they’re married and they’re coming in expecting.
"It’s just those little things that I’ve seen in the last six years that’s been amazing," she said.
Mrs McKenzie plans to "fully retire" with her husband Allen, now both 67.
The couple have four adult children between them and four grandchildren.
They are looking forward to travelling north in their caravan to see family.
"We really want to see Kerikeri. I want to go right to the top," she said.
Born and bred in Oamaru, Mrs McKenzie attended Waitaki Girls’ High School. After leaving school, she worked in retail at Haywrights department store, now known as Farmers.
She and her husband had a contract business for Herbert Sawmill, and she also worked at Countdown for two years and Whitestone Cheese for four years.
She bought the clothing store in 2018 to "work smarter, not harder" she said.
With a "good knack" for remembering faces, she would often see customers pull up outside the shop and by the time they entered, she would already have their consignment money ready for them.
"They’d say, how do you do that?"
She has some funny memories too, saying clients sometimes ended up buying their own clothes back.
The job sometimes came with challenges, she said, but for Mrs McKenzie it had all been about building good relationships.
"People coming in with deceased estate stuff, that’s hard, that’s really hard sometimes," she said.
A customer one day told her that she sounded more like a counsellor.
"I’ll miss the people."
Mrs McKenzie and her husband have leased the business initially. They still own the building, which also has a residence above the clothing store. She said the ultimate goal was to sell the building and perhaps their Oamaru home also, but their plans are "up in the air."
"We’ll do some travelling first and see what happens."
