Walsh made an incredible debut at his first senior international competition, with a bronze medal at the 2014 world indoor championships. He set an indoor national record in qualifying, beating it three times in the final to also claim the Oceania indoor mark.
After consistently improving his national record, Walsh recorded a second-place finish at the 2014 Commonwealth Games, only beaten by Jamician O'Dayne Richards.
The 29-year-old finished 2015 in style to win his first Diamond League meet with a throw of 21.39m in Brussels.
He started the year on fire, winning the world indoor championships, and breaking the NZ national and Oceania record in the process, before going on to claim a bronze medal at the Rio Olympics.
Walsh retained his indoor world title with a personal best throw of 22.31m, which moved him into the top-10 all-time.
At the 2018 Commonwealth Games, Walsh threw a new Games record in qualifying, before convincingly claiming gold in the final.
