Last Saturday in Nelson she ran on to the pitch wearing No.15 on her black jersey and played the full 80 minutes.
Every step of the way Holmes has talked about how fortunate she was, with no expectations of making it any further than she already had.
That humility and her desire to soak up as much knowledge as she could helped her rise quickly through the ranks and into a starting place with the Black Ferns.
Holmes had spoken in the past about juggling her sevens and rugby, saying it was a tough balance.
She is still walking that tightrope, having been selected to play in the upcoming Red Bull Ignite7 tournament, where she won the MVP (most valuable player) award last year.
What is certain is that this sporting prodigy has shown she has all the makings of success.
