As well as individual form there are other key areas of concern including their centre-pass to score rate, through-court defensive intensity, and ability to adjust to the umpiring.
Taumaunu said there was no need for any major changes to their gameplan or widespread personnel changes.
Taumaunu will test new players in the midcourt in the upcoming series, with newcomer Katarina Cooper set to become the third player to debut for the Ferns this year behind Courtney Tairi and Shannon Francois.
Francois emerged as a genuine contender after being called into the line-up for the Australian leg of the series. By the end of the series the youngster was the Ferns' first-choice wing attack.
Cooper will be looking to make a similar impact next week.
If she produces the same sort of confident and composed performances as she did in Silver Ferns trials earlier this year, which led to her shock selection, she will be in with a good shot of getting a call-up for the tour to the United Kingdom early next year.
Taumaunu is planning on taking an extended squad on the January tour, which may include Harrison, who gave birth to her first child last month, as well as a couple of players returning from injury.
The tour will likely play a big role in the selectors' decision-making in terms of who will make the cut for the Commonwealth Games team.
