In domestic netball, Kopua played her entire career with the Waikato Bay of Plenty Magic, starting in 2003. During the 2008 ANZ Championship season, she was named the Holden Captiva player of the championship, winning a new car.
On 11 October 2014, Kopua became the most capped New Zealand netball captain in history, playing her 63rd test as captain of the team in the 3rd test of the 2014 Constellation Cup against Australia.[5] In the fourth quarter of that match, Kopua suffered a suspected dislocated patella (knee injury). Scans later revealed that Kopua also ruptured her patella tendon.[6] Three days later Kopua underwent surgery to repair her patella tendon.[7]
In 2017, still rehabing from her surgery, Kopua announced her retirement from the Silver Ferns, stating she would return to the Waikato Bay of Plenty Magic in 2018, but would not be available for international selection.[8] Kopua was coaxed back to the national team by Noeline Taurua for the 2019 Netball World Cup.[9] She retired from netball after the World Cup.
