The contestants on The Block NZ: Firehouse were stunned by a shock announcement on Monday night's episode that saw a fifth team enter the fray.

Amy and Stu, the Gisborne couple that won the competition in 2018, returned as Team Black in an unprecedented move for the Kiwi renovation show.
Moving into the previously uninhabited apartment five in the fire house, Amy and Stu will be delivering a family bathroom along with the other teams.
"The whole game has changed," Mikaere said after the announcement.
Not everyone was pleased about the new additions to the game, especially considering Amy and Stu will be eligible to keep the $7,000 prize money from TSB if the other teams can't beat them.
"I'm not excited. Because we won't win, we can't," Stacey whispered to her partner Adam following the news.
"It was always going to be a hard week and it's just got even harder," Adam said.
