RIVERROCK ANGUS
Riverrock Angus Stud
At Riverrock Farm, we are boutique Angus breeders with a focus on quality over quantity. Established in 2023, we handpicked top-tier genetics from Meadowslea, Turiroa and Atahua to begin a breeding program centred around soundness, performance, and profitability.
Our goal is to produce easy-handling cattle that offer strong returns for their owners. We specialise in breeding medium-sized stud bulls with an emphasis on calving ease, short gestation periods, and early maturity, traits that enhance both productivity and ease of management.
Whether you're a commercial producer or stud breeder, our cattle are designed to meet the practical demands of the industry and you can rest assured you're buying from an honest source.
We look forward to offering our bulls and meeting many of you.

Where these figures come from
Every figure on these pages is read from the Angus New Zealand record for that animal on Helical, taken on 24 August 2026. The analysis carried on those records is dated 7 August 2026, and percentiles are stated against the 2024 Born Average. Angus New Zealand republishes breeding values with each analysis run, so a figure can move.
Nothing here is typed in by hand. The website, the one bull PDFs and the full catalogue are all built from the same file, so they cannot drift apart.
