It's another first for The Block NZ this year!
After Team Purple found itself needing to swap a teammate when Jaana was unable to return, Team Yellow needed to call in some special help too when one of their own was injured.
West Coast tradie Keegan suffered a painful fractured rib during a Block challenge, which saw him struggling to keep up and unable to get bed rest.
But who do you get to work on The Block NZ for free, at short notice, while they're filmed on national television?
Your other sibling!
"The third member of the Crawford trio's come to help us out in Auckland."
Sister and school sports coordinator Maddy was called up from Greymouth to become a sub with the extra arms for Keegan on House 3, while he is on physical rest.
Maddy is said to be quite artistic, with a few DIY skills up her sleeve too. She'll be on-site with her brothers for a couple of weeks until her younger brother has recovered enough.
