A Black Ferns team featuring four changes are targeting a clean sweep of their three-Test tour when they face Ireland in Dublin.
After tight wins over England and Canada, coach Glenn Moore hopes they can finish in style on Sunday although he is wary of an Irish side who beat them when the teams last met.
That was at the World Cup in France two years ago, when the 17-14 defeat in pool play ended the Black Ferns' hopes of winning a fifth successive title.
New Zealand have since returned to No.1 in the rankings while Ireland are fifth.
"There's a lot more in us yet," Moore said.
"The good thing is we've come over here and we've had to win tough and hang tough and fight it right out to the finish. That's been good for the squad and ultimately we'll get the benefits of that."
Moore says the tight turnaround between Tests is good preparation for next year's World Cup, hosted by Ireland.
Hooker Sosoli Talawadua will make her Test debut if used off the reserves bench.
