Nathan-Wong has handled the pressure with aplomb but never stops working to improve. Take her kicking, for example.
"You can't just hope that you'll turn up and it will turn out. I never knew how to drop kick until I first started our programme, but I had help from our assistant coach Allan Bunting and also Steve Miln."
Invariably her kickoffs are high and on the money. She reckons her fitness is also high, but is not resting on her laurels, not after the sacrifices she has made " a promising touch career on hold, and a 15s game stalled at club level, though that may change post-Olympics.
But the rewards have made it worth it. As a contracted player, Nathan-Wong earns a retainer which, while not enough to live off, makes life easier.
"It's an awesome first step for women's rugby to have these contracts. It shows how the women's game in New Zealand has grown."
She fits in correspondence studies at Massey University towards a Bachelor of Sport and Exercise degree. Nutrition is still provided through her grandfather and family cook Dave Wong. Life seems good for Tyla Nathan-Wong.
