About us

With 75 years of experience between them, TopFruit and Agristar joined forces and formed the company, TopNut. 

TopNut benefits from TopFruit’s experience in the introduction and commercialisation of new fruit varieties. TopFruit’s focus is to discover and unlock the potential of these new varieties for producers. This is achieved through variety development, a strong program of intellectual property management, brand development, and innovative marketing initiatives.

TopNut benefits from Agristar’s experience in the tree nut value chain from Nursery, Farming, Processing, Marketing and Retail. Agristar proudly supplies only the best quality Macadamia and tree-nut products by focusing on their commitment to customers, employees and stakeholders.
