Zonderland competed down under at the 2019 Melbourne World Cup in Melbourne, Australia, from February 21 to 24, 2019. He and Hidetaka Miyachi of Japan scored identical highest combined scores of 14.733 in the individual horizontal bar apparatus final. However, after activating the tiebreak procedure, Zonderland was relegated to the silver medal because Miyachi's execution score number was higher than his own. Also, between April 10 and 14, 2019, at the European Artistic Gymnastics Championships–an FIG championships held in Szczecin, Poland—Zonderland won his third European gold medal in the individual horizontal bar apparatus final. However, he failed to qualify for the same event final at the 2019 World Artistic Gymnastics Championships in Stuttgart after an error in his routine.
