In March 2021 it was announced that Conder has been awarded the 2020 Euler Medal by the Institute of Combinatorics and its Applications for his "many distinguished contributions to combinatorics over the last 40 years."

In 2014 the Royal Society Te Apārangi awarded Conder the Hector Medal, and in 2018 the Jones Medal, named after Vaughan Jones, "for his internationally renowned research on symmetry and chirality in discrete structures, and his exemplary leadership and service in the New Zealand mathematical sciences community". In the 2020 Birthday Honours, he was appointed an Officer of the New Zealand Order of Merit (ONZM) for services to mathematics.
