Selling tartan to Alaskans is easier when you have Irish ancestry.
The Scottish Shop owner Erin Hogan has decided to put her George St shop on the market because she wants to retire.
She bought the shop as a going concern in 2001, and later diversified her business model, hiring kilts and selling goods online to customers as far away as Alaska.
The shop's success was also due to the closure of other Scottish shops in New Zealand.
Her Irish heritage helped with business because it allowed her to keep out of ''clan feuds''.
''Imagine if I had a name like Campbell, and a McDonald came in? I don't have that issue because I'm Irish. It keeps me neutral.''
Her ancestry allowed her to deny Scottish customers their birthright - a discount.
''I say, no, because you're Scottish I'll charge you double,'' she said, laughing.
A perk of the business was travelling to Scotland for trade fairs every three years.
On the trips, she made many Scottish friends.
''We all meet up, go out for a laugh and I get lost in their accents.''
The Scottish music played in the shop was mostly enjoyable.
''Unless it's particularly bad, like heavy solo piping - it gets on your goat.''
