And as first reported by the Herald on Monday, Harris-Tavita, who was named the club's 2019 NRL rookie of the year, gets the first chance in the critical No 6 jersey.
It's reflects the massive progress by the 20-year-old over the last 12 months, as he was stuck behind Adam Keighran at this point last year.
The most intriguing selections are prop Jamayne Taunoa-Brown and second rower Eliesa Katoa, who are poised to play their first games in the NRL, after being included on the interchange bench.
It caps a whirlwind rise for Taunoa-Brown (23), going from a train and trial contract to a fulltime deal after representing the Warriors at the Perth NRL Nines and joining the Australian Indigenous squad for the All-Stars clash against the Maori Kiwis last month.
Taunoa-Brown, who also has Maori heritage, has previously played lower grade football during stints with the Melbourne Storm, Newcastle Knights and Norths Devils (Queensland Cup).
Katoa (20) was picked up by the Warriors after standing out for Tamaki College First XV in 2018.
Born in Hihifo in Tonga, Katoa has impressed throughout the offseason after having his first taste of league in the under-20 competition last year.
While the young duo are in, prop Agnatius Paasi (ankle) and back rower Josh Curran (calf) haven't been named due to injury.
In Paasi's absence, Lachlan Burr partners Leeson Ah Mau in the starting front row while new signing Wayde Egan is named at hooker.
Kodi Nikorima will be used off the bench, similar to his role at the Broncos in 2015, while back-up hooker Karl Lawton is also named after off season shoulder surgery.
Second rower Tohu Harris is back, set to start an NRL match for the first time since last June, after a prolonged foot injury.
It will be the third time in the last six seasons that the Warriors have opened the season against the Knights, with a loss in 2015 (away) and a victory in Stephen Kearney's first match in charge in 2017 at Mt Smart.
The Warriors have won two of their last three matches at McDonald Jones Stadium and overall have a 8-10 win-loss record in Newcastle.
