NZG was founded by Gerhard Schmid and Betty Hauer in Nuremberg in 1968. The company specializes in diecast models of construction vehicles, in 1:50 scale, but also in 1:25 and 1:87. In the late 1970s, NZG began to collaborate with Mercedes. NZG increased its popularity in the 1980s, when, after an agreement with Porsche, it reproduced all the contemporary models of the Stuttgart company, with the original colours, opening parts and a good level of fidelity. NZG subsequently concentrated on commercial vehicle models. Since 2017, 1:18 scale diecast models have also been part of the range; the 1:12 scale, which is increasingly successful, has also been added to the catalogue.
