The nine remaining contestants arrive in New Zealand and embark on the adventure of a lifetime, starting with a visit to Sky Harbor, a popular tourist attraction known for its breathtaking views. Awaiting them are 51 flights of stairs to climb followed by the adrenaline rush of sky-jumping for contestants and trainers. Then it's on to a 5K challenge New Zealand-style, with the winning team getting an unforgettable helicopter ride to gorgeous Waiheke Island. The trainers take contestants to the Auckland Fish Market, where they talk about eating healthy while travelling abroad, and Jillian has a lively lobster encounter. Later, the contestants charter an American Cup racing boat to sail around Auckland Harbor, and one player with a special connection to New Zealand gets a very generous gift.

The New Zealand adventure continues in Queenstown, where the eight remaining contestants learn from host Alison Sweeney that the game is going to singles. Then a special visitor surprises all of the players with a grand and unforgettable entrance! This week's challenge is river surfing, with the winning contestant getting the coveted prize of immunity plus a helicopter ride to spectacular Milford Sound, one of New Zealand's top tourist destinations. Zip-lining, rock climbing and bungee jumping highlight the rest of their memorable Queenstown experience before a weigh-in sends another player home.

It's "Favorites Week" on the ranch, and the remaining seven players participate in a favorite past season challenge - pulling a car for a half mile. Popular NASCAR driver Clint Bowyer is there to cheer them on at the speedway, and Tara Costa, the season seven winner of this challenge, returns to compete alongside the contestants for some amazing prizes. Later, popular season nine contestant Sam Poueu and season five winner Ali Vincent put the contestants through a workout in the gym, and also motivate the players one-on-one. Then it's a weigh-in full of surprises, leading to one more contestant facing eliminaton.
