It can vary in length between 3 and 25mm in length, but the most common is 9mm. They are a part of the superfamily Scarabaeoidea and are characterized for their modified prothorax and have a large coxae.

The manuka beetle is a part of the subfamily Melolonthinaes, which is characterized by its stout body and glossy exterior, and the presence of either labrums or mandibles. These appear as segments either elongated or as oval lobes which can be folded together tightly to form compact and asymmetrical clubs. The elbow clubs have between 8 and 10 segments. They have spindly legs covered in light coloured hairs which are strongly modified for digging with their teeth, spines and/or bristles. Their abdomens have 6 ventrites and the hind wing has a spring mechanism which can fold.
As larvae, the grub forms as a C-shape.
