When NZ Warriors travel to Suncorp Stadium on Saturday, the number one No.1 may just be the decisive factor in which team book their place in the NRL Grand Final.
As the Warriors strolled to a 40-10 victory over Newcastle Knights, Nicoll-Klokstad, 28, stood tallest as the best player on the ground and had the decisive say in the result.
Playing all 80 minutes, Nicoll-Klokstad ran 32 times for just short of 300 metres, including 101 after contact. He also scored a try, assisted another, broke the line once and created another linebreak assist, as well as breaking eight tackles.
So intense was Nicoll-Klokstad's display, Warriors captain Tohu Harris had to tell him to "calm down" to avoid burning himself out.
His efforts overshadowed those of Knights counterpart Kalyn Ponga, who was instrumental in leading his team to the semi-final.
The Knights had won their last 10 games, with Ponga scoring five times and assisting a further 14, as his side's best player, but against the Warriors, he had next to no impact, as the home side produced their most complete performance of the year.
Next weekend, Nicoll-Klokstad will have a tougher task against a player that was in his shoes just a year ago.
After leaving the Warriors to return to the Broncos, Reece Walsh has been one of the lynchpins for coach Kevin Walters. In 20 games this year, Walsh has scored nine times and assisted 22 tries, averaging 153 running metres per game.
Walsh even displaced Ponga at State of Origin level for Queensland, in a changing of the guard for one of the game's best fullbacks.
If not for a suspension in June for swearing at a referee, Walsh would almost certainly be in contention for this year's Dally M Medal, along with Warriors halfback Shaun Johnson and teammate Payne Haas.
Instead, the Provan-Summons Trophy is the best Walsh can hope for.
Former Warriors coach Tony Kemp predicts Walsh's input is the biggest worry, as the Auckland-based club looks to reach its first Grand Final since 2011.
But in Nicoll-Klokstad, the Warriors have the perfect antidote.
"The guy that no-one's talked about is Reece Walsh at fullback," Kemp told AM. "He's arguably the best fullback in the competition, but Charzne Nicoll-Klokstad on the weekend ran for 300 metres, which is unbelievable.
"You had Kalyn Ponga on the other side and Charzne was the best player on the pitch. He has to produce another performance like that."
The Warriors and Broncos have met once already this season, with Brisbane taking a 26-22 victory in controversial circumstances, when a late try to Marcelo Montoya was ruled out for an Adam Pompey jersey pull.
However, Walsh was absent on State of Origin duty for that clash in Napier.
