Johannes Hendrik “Ponie” van der Westhuizen was a talented and versatile back who emerged from the rich rugby culture of Stellenbosch University, following in the footsteps of his older brother, J.C. van der Westhuizen, another Springbok of the 1930s. A strong and dependable player rather than a flashy one, Ponie earned his reputation through consistency, intelligence, and a deep understanding of the game - qualities that made him a valuable asset to every side he represented.

While studying at Stellenbosch, van der Westhuizen became a key member of the Maties rugby team, which at the time was the dominant force in South African university rugby. His ability to cover both wing and full-back made him an indispensable utility back. Though described as “not brilliant,” his value lay in his reliability - a player who seldom made mistakes and could be counted on in both attack and defence.

As a full-back, he was known for his safe hands and excellent positional play, while his touch-kicking was regarded as among the best in the Western Province. When deployed on the wing, van der Westhuizen’s pace, sidestep, and willingness to go looking for work made him an attacking threat. His strength on the ball and ability to break tackles complemented his defensive discipline, earning him the respect of teammates and opponents alike.

By 1931, at just 21 years old, van der Westhuizen had already become the cornerstone of the Stellenbosch backline, a player who could be trusted in pressure situations and who epitomised the Maties’ structured yet enterprising brand of rugby. Though his international career was brief, his contribution came at a time when South African rugby was flourishing with young talent, and his connection to the famous van der Westhuizen rugby family added to a legacy of skill, sportsmanship, and quiet excellence that endured long after his playing days.
