Todd got selected to represent New Zealand at the 2016 Summer Olympics. Once again he became the second oldest New Zealand Olympian in history, as the fellow equestrian Julie Brougham made her Olympic debut at the age of 62. At the Games held in Rio de Janeiro, Brazil, Todd finished 4th in the team competition and 7th individually. Todd was the last team member to compete in the jumping phase, however, he uncharacteristically dropped four rails. As a result, New Zealand team missed out on a possible gold medal. Todd later described this outcome as one of the biggest lows of his career.
