Tracked

The teams chopper into their first challenge in the rugged Southern Alps, and soon feel the pressure as the trackers start their chase, hungry for a capture.

The seven remaining teams struggle in the extreme bush of Fiordland; cracks start to emerge between teammates when they get completely lost.

Team Orange lose their map again, creating more friction; Team Blue comes under intense pressure, as they are strategically targeted by the remaining teams.

The 24 hour challenge sees teams chased day and night by the trackers, who have doubled up their numbers to add even more pressure on the exhausted contestants.

With four teams remaining, the pressure to escape from the relentless trackers is intensified; plus, for one team, an argument leads to a catastrophic sequence of events.
