Taumaunu said she expected some very robust conversations with the selection panel as they seek the right mix to go through to next year's Commonwealth Games.
After a rusty start to trials, the coach said she was much happier with the performances on day two. The players have a heavy workload, playing 10 quarters each day across two sessions, but Taumaunu is pleased with the way the combinations have developed despite the players being tired.
"Our first one was a bit messy, yesterday we were pretty inconsistent so I was much happier with this morning's run. There were some combinations that took a bit of time to settle, but much less time than yesterday."
One of the surprises has been young Tactix defender Jane Watson, 23, who impressed at goal defence yesterday despite an elbow injury. Traditionally a goal keep, she had her arm heavily strapped after hyper-extending her elbow in a fall on Tuesday. But it didn't slow her down. She combined well with Katrina Grant in the defensive circle to come up with some brilliant turnover ball.
Taumaunu said Watson was originally invited into trials with an eye to the future, but her form might force selectors into a rethink.
"I'm really pleased with the progress she's made at goal defence, because it's not a position she has played a lot of," said Taumaunu. "She was probably more on the accelerant list but she has certainly made us think. It's not over yet."
Traditionally an area of strength, defence is unusually light in the Silver Ferns this season, with Anna Harrison out of the international season having her first baby.
There's a case for Watson's inclusion with another stand-out performance today, but she insists she's not thinking about selection. She said the opportunity to play with established Ferns had made this week an extremely valuable experience.
"Getting to work with them and learn from them is awesome."
