A local punter took a photo and posted it to social media, which has since gone viral.
The photographer told the Herald it was "hard case", said the sign was extremely Kiwi and explained the message was a true representation of what was really on sale.
"I took it on Sunday at the Soundshell market. And it was what it said on the sign... A bunch of tools, and s**t!. An absolute classic," he said.
Kiwis took to social media to poke fun at the sign and celebrate Kiwis saying typically Kiwi things.
"I've completely lost my s**t so this is timely", one wrote.
Another said: "Always need a bunch of other s**t to finish the job. Story of my life."
Others said they'd have "definitely checked it out" and called the sign "top-notch Kiwiana."
