True to their name, the arrival of the "disruptors" left a lasting mark on the game when relationships, loyalty and sincerity were put to the test.
The pair are Natasha Pezic, 23, a lifestyle blogger from Auckland, and former bodybuilding champion Lincoln Marshall, 22, from Marlborough.
On her first night on the island Natasha kisses a number of the boys and ranks Kristian as the "best" out of all of them in front of his current partner Ruby.
She is obviously distraught and later asks him what he meant by it.
He then refuses to apologise and acts like it was a "strategy" to "play the game".
Playback gets tense
After the disgusting food challenge, Georgia and Harry were in a tight spot after being put up for elimination.
Hosts Matilda and Mark asked the players for the Playback option where you can swap your partner to save one of the bottom two, and eliminate your current partner.
Ruby decided to play the Playback option to keep Harry in the game and say sayonara to Kristian.
Josh also used the Playback option to save Georgia, throwing his current partner Tiffany under the bus.
