One of Morrison's co-stars on the New Zealand soap opera Shortland Street was Daniel Logan, the future Boba Fett. Morrison also played alongside Rena Owen, who played both Nee Alavar and Taun We, in Once Were Warriors, and starred beside Harrison Ford (Han Solo) in Six Days, Seven Nights.

Temuera Morrison played Jango Fett and all clone troopers in Star Wars: Episode II Attack of the Clones. Morrison was the model for the CGI clone troopers in Star Wars: Episode III Revenge of the Sith and acted and voice-acted as Clone Commanders Cody, Davijaan "Odd Ball," Gree, Thire, and Appo, as well as Clone Captain Jag and Sergeant Fox. He also lent his voice to the character of Boba Fett for the 2004 DVD release of the original trilogy (replacing Jason Wingreen), and has voiced the Fetts and the clone troopers in many video games. He made his live-action debut as Boba Fett in "Chapter 9: The Marshal," a second season episode of The Mandalorian.
After Morrison's appearance in Attack of the Clones, artists used his likeness to depict Boba Fett and clone troopers without masks. Chapter 21 of Star Wars: Clone Wars was one of the first stories to do this. Infinities and Star Wars Tales stories have also depicted the unmasked Boba Fett bearing a strong resemblance to Morrison.
In 2005, prior to the release of Revenge of the Sith, Morrison released a special episode of his New Zealand talk show, The Tem Show, to commemorate his time in the Star Wars franchise, while also advertising the then-upcoming release of Revenge of the Sith. In the episode, Morrison interviewed fellow New Zealand actors Jay Laga'aia, Bodie Taylor and Rena Owen, as well as George Lucas (who was affectionately referred to as "Uncle George"), , Paul Giacoppo, and Rick McCallum.
