The Blues have named a settled team for the fixture, with star prop Krystal Murray expected to push through a niggle sustained against Matatū to take her spot in the starting front row, while captain Aroha Savage makes her debut in the No 8 jersey. The side also gets a lift on the bench in the form of Black Ferns lock Eloise Blackwell.
Chiefs Manawa get a similarly welcome lift with livewire centre Stacey Fluhler making her Super Rugby debut and Black Ferns hooker Grace Houpapa-Barrett named for the first time this season in the No 16 jersey. Rugby Tui returns to a starting role on the left wing after coming off the bench last weekend.
"We know the Chiefs are a really good side, but so are we. Hopefully we'll be good enough to get the job done," Fitzpatrick said.
While the Super Rugby Aupiki title is on the line, it will come with extra bragging rights in the Semple household, with Chelsea Semple lining up for the Chiefs and her husband, James, on the Blues coaching staff.
It will be the first time the two have been part of opposing teams, with James having coached Chelsea at Waikato in the Farah Palmer Cup.
"[Chelsea] actually said to me whoever wins wasn't allowed to say anything," James said.
"It's pretty healthy [banter] and it brings a good element to our relationship.
"I'll be in the dog box for a couple of weeks if we get the win, but that's alright – I'm happy with that."
Hurricanes Poua and Matatū will meet in today's earlier game, with Black Ferns star Kendra Cocksedge getting her first run in the competition for the South Island side, while Black Fern Te Kura Ngata-Aerangamate will get her first start at hooker for the Hurricanes.
