Marley Maheno owns ACA Clothing, which he runs as a side hustle to his IT day job.
He and his partner, Brooke, work from home on the T-shirts, which are printed on demand.
Maheno explained ACA Clothing received requests for all sorts of apparel including school wear, sportswear, memorial T-shirts and other special interests.
He said he designed the "Is the gorge open?" T-shirt about a month ago after a resident thought it would be funny to wear it in the Far North.
"It wasn't my idea, Grilla Tactix owner Reti Blair wanted it done, so I made one and put it out there on the website," Maheno said.
"Since then we've sold about seven."
Maheno said he'd received all kinds of requests for local colloquialisms over the years like "Any scallops on the beach?" and "Is Kaeo flooded?"
