Sweet As Tees › NZ Slang › Mint
Mint: Perfect, in excellent condition, brilliant. Pronunciation: mint.
"Mint" means perfect — as flawless as a coin straight from the mint. Kiwis use it for anything in top form: a second-hand car that runs like new ("she's mint, bro"), a cloudless Saturday ("mint day for it"), or a plan that comes together ("that worked out mint").
It shines brightest in the world of buying and selling — on Trade Me, "mint condition" is the highest state a second-hand item can achieve, and every Kiwi knows the gap between "mint", "pretty tidy" and "needs a bit of love" can be measured in hundreds of dollars.
"Mint" also joins the compliment ladder alongside choice and mean, and famously stars in the phrase "yeah nah she's mint" — Kiwi for "it's all good, honestly". Like most NZ praise words it's understated, which is exactly why it lands: when a Kiwi says something's mint, they mean it.
From "mint condition" — coins fresh from the mint, flawless and untouched. British and NZ slang clipped it to just "mint", and Kiwis ran with it for anything excellent: objects, plans, days, people. If it's mint, it couldn't be better.
