“I posted a couple of those on my Instagram and I was like, does anyone like this? Soon I got really good feedback on my posts and I thought to myself that I can actually make it work.”
Kat said some of her Gisborne friends put her in touch with Taiki e! Next Gen, a collaborative space for budding rangatahi entrepreneurs.
“That's how I got to set up my shop at the Next-Gen space last week.”
But Rehash Collective is not her first try at business.
As a 12-year-old, Kat established a tea company that shipped fresh mint tea leaves from her garden.
Then she tried her hand at embroidery and jewellery — an art form she credits her mother with for her influence.
“My mother owned her own company and did embroidery stuff. So I got the sense of running a small business and how she sold her stuff online.
“I saw the importance of marketing and how to enter the online spaces.”
Since setting up her shop last Monday, she had already had more than 40 customers visit the shop and buy.
Some of the special collectibles, such as official merchandise of the American baseball team Chicago Cubs, were quickly snapped up.
A few others are up for grabs, including a vintage No.12 jersey of the Harlem Globetrotters and a No. 24 jersey from West Michigan's Vipers.
Rehash Collective at Next Gen space, Treble Court is open until December 2.
