Jamayne Isaako needs 12 points to become only the fourth player in premiership history to reach 300 points in a season when the Dolphins face the Warriors.
The qualifying final at Go Media Stadium will give the winner a week off and a home preliminary final.
It is also the Dolphins' first NRL finals appearance, with the visitors arriving after seven straight victories.
The teams have split their two 2026 meetings, while every contest since May 2024 has been decided by two or four points.
The Warriors won 20-18 in Wellington during Round 8, before the Dolphins answered with a 26-24 victory at Suncorp Stadium in Round 17.
Selwyn Cobbo returns on the wing, Kodi Nikorima resumes at five-eighth and Kulikefu Finefeuiaki returns in the second row.
Connelly Lemuelu is on the interchange, Felise Kaufusi is 18th man, and Jake Averillo, Brian Pouniu and Tevita Naufahu move into the extended squad.
Jackson Ford returns for the Warriors after recovering from a pectoral injury that sidelined him since Round 16.
Leka Halasima is back from an ankle injury, while Wayde Egan and Kurt Capewell return after being rested last week.
James Fisher-Harris and Thomas Flegler provide the central forward battle, with the Warriors captain's experience contrasting with Flegler's return after an extended absence.
Fisher-Harris will try to drive momentum through the middle, while Flegler must disrupt the Warriors' pack and reinforce the Dolphins' defence.
