Castaways

Eighteen celebrities were separated into two tribes with te reo Māori names based on fauna of New Zealand: Kārearea and Tohorā, including the merged tribe as Weka.
For the first time in the game's history, the Captain's Coup was introduced. The day's winning team gets to pick a member from the losing team to go up against their captain. If the captain loses, they lose their captaincy, given to their teammate. If they win, they get to keep it.

Day 1 – Matt was chosen by Kārearea to go against his captain, Matilda. Matilda retained her captaincy.
Day 4 – James was chosen by Kārearea to go against his captain, Matilda. James won the coup.
Day 7 – Tohorā chose Eli to go against his captain, Jordan. Eli won the coup.
Day 8 – Tohorā used the block advantage card against Kārearea, who used the mercy card to save Jordan from elimination.
Day 10 – Teams entered the face-off, which ended as an individual immunity, and both teams merged. Nick won the first individual face-off.
Day 16 – Courtney won the face-off and placed herself in the elimination challenge. She won her spot in the final three.
