Wellington has six of the best returning.
That will make it hard for Otago to secure its first victory in the Hallyburton Johnstone Shield in more than two years.
The Sparks are on a 19-game losing streak in the format but have been bolstered by the return of internationals Katey Martin and Hayley Jensen for the games against the Blaze at the Basin Reserve this weekend.
But Wellington has had a significant boost as well. It welcomes back six internationals.
Star batswoman Sophie Devine will make her first appearance for the Blaze in the one-day tournament in more than two years.
Maddy Green is poised to make her list A debut for Wellington after shifting south from Auckland last summer.
The Kerr sisters, Melie and Jess, spinner Leigh Kasperek and Thamsyn Newton all return after featuring for the White Ferns during the disappointing T20 series loss to England.
Blaze coach Ivan Tissera has an all-star team to call on.
It has come too late in the tournament, however. Wellington is second-to-last with two wins and cannot make the final.
Canterbury, Auckland and Central Districts will jostle for that right.
Canterbury and Auckland play each other at Eden Park Outer Oval, while Central Districts will host Northern Districts at Pukekura Park.
Otago has long been out of the running. The province is in a rebuilding phase and has not been that competitive.
Looking at the personnel in both sides, Wellington should ease to comfortable victories in the back-to-back matches.
For the Sparks, it will be more about playing as well as they can and looking for the likes of Caitlin Blakely to continue her good form with the bat in the competition. She has scored 242 runs at an average of 34.57, while spinners Eden Carson (10 wickets at 33.30) and Sophie Oldershaw (seven wickets at 34.42) and seamer Emma Black (10 wickets at 30.70) have been solid.
Molly Loe has shown promise with the ball as well, and all-rounder Saffron Wilson has taken her opportunities.
The reality, though, is the Sparks, playing what is close to an international strength side, may have to wait until next season to snap the losing streak.
