Marty's Meats Smash Burgers is a burger business in Nelson that began as a food truck. It now has a dine-in space at Morrison Square in the Nelson CBD, and the food truck still operates just before the gates at Nelson Airport. The burgers are made with 55-day wet-aged prime cuts from Pure South, cut, minced and formed on site in a chiller kept at 2 degrees. The fries are freshly cut and cooked in beef tallow, the sauces are house-made and cooked for 10 hours, and the cookies are made in house. The website says nothing is frozen.
Customers praise the chilli bourbon sauce, the garlic butter burger, the classic and purist cheeseburgers, and the fries, which one reviewer called the best they have had. One says a combo at $25 as at 2026 gave a large burger, chips, a drink and a sauce. Orders can be placed by phone on 021 195 7517 for the CBD.
