Big Dyls (Dylan Cossey) from The Block NZ is selling himself for surf lessons, to raise money for a cause close to home.
When Foster Hope, a charity who make up backpacks for children when they are removed from their home into foster care, approached Mr Cossey he jumped at the chance to help.
"Foster Hope is a charity you don't hear a lot of about it. It rings really true to me, it just hits home because I've seen it first hand. To see where some of these kids come from, some from sexual abuse and mental, verbal and physical abuse."
Mr Cossey and his siblings grew up seeing foster children turning up to his house in the early hours of the morning, with rubbish bags holding their belongings.
He estimated his family had seen about 15 to 20 foster children come through their home.
