About us

About us

We manage and advise only in those primary sectors we understand deeply.

Primary Partners was established in 2013 in response to investor and institutional demand for a service to source and fully manage large scale New Zealand sheep and beef farms. We have built a strong reputation for our robust investment strategies and analytical approach to managing and extracting value from farm assets.
