Mrs McAtamney (62) said although she was sad to see the shop go, ill health prevented her from continuing its operation.
She bought the Art Deco building on Ranfurly's main street in 2000, and had since run Decollectables from it.
"It's a very sad day for Ranfurly and a very sad day for me," she said before closing the doors yesterday.
Sourcing Art Deco furniture, jewellery, ornaments, clothing, and other trinkets from throughout New Zealand had been an enjoyable job, she said.
"I've always tried to keep it true to the Art Deco era with good original pieces that aren't damaged. It's become quite difficult to source original pieces, whether they are furniture, lights, or anything else, that aren't damaged because they are getting on in age," she said.
In recent years, word had spread about Decollectables, and sourcing items was not difficult.
"It just walks in the door now - people bring it in. It is a very good little business, and it's sad to close because the Art Deco project has really enhanced the architecture, knowledge, and community spirit in this little town."
At the time she purchased Decollectables there were 13 empty shops in Ranfurly, and Mrs McAtamney wanted to "get the ball rolling".
"We had just finished the revitalisation of the Centennial Milk Bar. Opening Decollectables was part of the Art Deco community project really."
The property was first advertised for sale in February, to coincide with Ranfurly's annual Rural Art Deco Maniototo festival, which Mrs McAtamney started.
A closing down sale which began during the February 27 and 28 festival had ensured "nine-tenths" of the shop's stock had been sold, she said. All remaining items would be removed from the shop on Monday and most likely sold at auction in Dunedin, Christchurch, or Auckland.
Mrs McAtamney had received "a lot of interest" in the property, but was unable to continue managing the shop as some prospective buyers had hoped.
An injury in 2006 had resulted in nine operations since, and Mrs McAtamney said she was no longer able to sustain physical work.
"There's no other reason I'm selling. It's an attraction and a destination in its own right."
Mrs McAtamney and husband David will continue to base themselves in Ranfurly, where they run a bed and breakfast business. Mr McAtamney also farms and operates a tourism business associated with the Otago Central Rail Trail.
The couple also own a home in Wanaka.
"I'm not going to get better until I start resting. There's plenty of work in me yet, just not physical work," Mrs McAtamney said.
