The company has closed its Rotorua store and Marbecks in Wellington which had operated for 17 years. When the Queen's Arcade store closes, there will be six Marbecks left around the country, none in Auckland.
Mr Harper said there was a possibility the store could be shifted to Hobson St - next to a new cafe: Marbecks Kitchen, opening today. The cafe is decorated in all things music.
There are plans to have live bands playing there regularly, although Mr Harper said at the moment there were no plans to sell music there.
"This is the evolution for us," Mr Harper said.
Roger Marbeck, the former owner of Marbecks and grandson of the original owner, said: "It's very sad to see it go. It's been in existence for almost 80 years and is very dear to our family. But the [industry] is a changing scene.
"It's hard to do business in New Zealand because rents are so hard ... it's tough out there for retailers."
Mr Marbeck's grandfather Alfred and his brother-in-law Noel Wade opened the Queen's Arcade shop in 1935. His father, Murray, took over the family business before passing it over to him. Mr Marbeck sold the store in 2006 and is now with Ode Records.
Mr Marbeck said it was a great thing for a young boy to grow up around music and particularly at that store.
"I was the cleaning boy, when I was very small. It was like lots of those family businesses back in those days. It was the golden era.
"My grandfather had a piano there and he sold sheet music. There was a gramophone and then records and later it was cassettes and CDs. Now it's digital. It's just the way things go."
A closing down sale will start next week.
