In April 1946, the cornerstone of the company's new headquarters was laid in Corrie de Kock Street, Klerksdorp and the building was completed and inaugurated the following year. The official opening was conducted by Mr JJ Adams, the Deputy Secretary of Agriculture and Registrar of Co-operative Companies. During the same period, Senwes launched the processing of peanuts as a new production line, and by 1949, the company had expanded its trading activities to include animal feed and edible oils.

In the 1950s, the company was a founding member of Sentraboer (Co-operative) Limited in 1950, which provided insurance cover for the harvests and assets of its members. In 1951, Senwes launched seed processing as an additional service to members, further strengthening its position as a leading agricultural co-operative. Additionally, in February 1956, Senwes registered its activities in the then-South West Africa (now Namibia) as a co-operative company with limited liability under the Ordinance on Co-operative Societies, 1946 (Ordinance 15 of 1946).

In the 1960s, Senwes launched a series of initiatives aimed at modernising and improving its operations. These included a comprehensive grain-lift construction programme in 1962 to enhance the handling and management of bulk grain, the computerisation of systems at its headquarters using IBM-machines in 1965 (which were later upgraded to more powerful computers), and the establishment of an agricultural science and information department in 1969.

In 1971, Senwesko held its first farmers' day, which attracted 700 members and was a great success. Two years later, the company formally adopted a new corporate identity featuring a corn cob emblem, and its research division made history by receiving approval for two new maize cultivars and a soya bean cultivar. In 1977, Senwes further expanded its operations by opening a peanut-sorting plant in Wesselsbron, and in 1978-1979, the company established its new headquarters at Charel de Klerk Street in Klerksdorp, adjacent to the N12-highway

In the early 1980s, Senwes made significant investments in expanding its operations and improving its infrastructure. In 1982, the company established its own fertiliser plant in Viljoenskroon, followed by the completion of a peanut-dehusking plant at Bultfontein in 1983. That same year, Senwes also underwent a name change, becoming an agricultural co-operative with limited liability in accordance with the Co-operatives Act (Act 91 of 1981).

In 1997, Senwes underwent a major transformation when it changed from an agricultural co-operative with limited liability to a profit-driven company competing in the free market. The company's new corporate identity was officially introduced on 23 July of that year, after it had been established as a company on April 10.

In May 2000, Senwes participated in the Nampo Harvest Day for the first time and in February 2001, the company introduced the SAP-management system. In 2002, a value-creation strategy was implemented, the first female group secretary was appointed and Senwes embarked on a black economic empowerment path. The Bafokeng Consortium acquired a 27,14% interest in Senwes in 2005. The company adopted a new logo in September 2008, leading up to the official celebration of Senwes' 100-year anniversary on 15 May 2009.

The 2010s were marked by the implementation of a 10-year rolling strategy based on six core pillars. This strategic approach led Senwes to diversify and expand geographically, broadening its product and service offerings through multiple mergers and acquisitions. The 2015/16 season brought about the most severe El Niño drought phenomenon in the country's history. Two years later, Senwes successfully managed and stored the largest maize crop ever produced in South Africa.

The early 2020s will be globally remembered not only for the devastating effects of the COVID-19 pandemic but also as a time of great instability, digital transformation, and rapid transition to a new normal. As we progress through 2024, the agricultural sector has faced significant challenges, including adverse El Niño conditions, which have impacted weather patterns and crop yields. Despite these hurdles, Senwes has demonstrated remarkable resilience and adaptability. Through strategic initiatives, effective risk management, and the ongoing realisation of synergies from recent mergers and business model reorganisations, we have achieved unprecedented success. In 2024, Senwes delivered a profit exceeding R900 million. This milestone underscores our commitment to innovation, sustainability, and the long-term prosperity of our stakeholders.
