Crawford, 31, and his sister Libby, 29, won the hit TV show on Thursday when the Takapuna house they renovated sold at auction for $961,000 - $157,000 above valuation. They kept the latter amount and a further $80,000 as winners.
Ben, who was a hit with female viewers on The Block, yesterday played down rumours of a romance with Hutchison, insisting they were "just good friends".
He said he first met the stunning Kiwi actress, 26, through a mutual pal at a party for Starship hospital two weeks ago.
"Look, Anna is really nice and it would be good to stay friends with her," he told the Herald On Sunday. "There is nothing more to it than that - sadly. We were just out having a bit of a laugh."
Meanwhile, the show's second-placed contestants, Richard Boobyer and Sarah Adams, were yesterday issuing a denial of a different kind.
The Hamilton couple, who made $64,000 on the programme, came back to earth when they arrived home and got stuck straight into weeding the garden.
Accompanied by Sarah's mother, Sharon, they shot down rumours circulating on the internet that their four-year relationship was over.
"We first heard about this at the live auction final," Sarah, 20, said. "It is pathetic that people are putting that kind of nasty stuff about on Facebook and other sites, because it simply isn't true."
