After the first episode aired, the television show and building company's Facebook pages were plastered with outraged messages and claims the show's producers broke the rules.
A TVNZ representative said host Simon Barnett's comment about completing models was intended only to emphasise that teams would be under pressure to deliver a thought-out house plan within 24 hours, and apologised for any confusion.
Builder judge David Reid had been impressed with Fail and Blair's model despite them not cutting out the windows.
In an attempt to dampen Facebook exchanges, firefighter Clarkson - who rescued injured people from Christchurch's earthquake-hit CTV building - posted a conciliatory message, saying he was upset at not being selected but supported the remaining contestants.
"It was an emotional time for us, totally gutted, it really helps seeing all your messages," wrote Clarkson.
Fiancee McManus told the Herald on Sunday that she looked at social media straight after Tuesday night's episode "because my sister thought it might make me feel better".
She was surprised at the extent of support.
In another twist, Mitre 10's Facebook page revealed foster parents Martyn and Sarah Giles received the most public votes, which was not being announced on the show.
Said the Mitre 10 Facebook page: "The judges were really impressed by Jay and Amanda's layout so much so they said they didn't know any novices that could design to this standard. And Marty and Sarah voted in by the public are also just incredible people. "
TVNZ said some information had been published online but the broadcaster did not wish to reveal who won the vote as it could affect teams' chances as the competition progressed.
