Popstars is an international reality television franchise and a precursor to the Idol series. The series first began in New Zealand in 1999 when producer Jonathan Dowling formed the five member all-girl group TrueBliss. Popstars remains one of the most successful TV show formats of all time with the format being sold to more than 50 countries. The show was the inspiration for Simon Fuller's Pop Idol franchise.
In April 2021, TVNZ debuted a 24 episode second season of Popstars. The show format was revamped. Unlike the original show in 1999, it was not a documentary following the formation of a girl group. Instead, the reboot focused on individual artists — both solo artists and groups of any gender, aged 16 or older, and placed its emphasis on original songwriting from the performers themselves.
The series involved a panel of three experts, headed by Kimbra, who was joined by Nathan King and Vince Harder. In the auditions phase, the singers were first assessed by vocal coaches Bella Kalolo and Jeremy Redmore.
The series screened on TVNZ 2 on Monday, Tuesday, and Wednesday nights.
