Watch the amazing moment Shona from Christchurch won her mortgage paid for a whole year

Sparklers went off and confetti flew as Shona from Christchurch unlocked the Live Free door - winning her mortgage paid for an entire year thanks to OneRoof.

She was among the one of the five key winners who had made their way up to Auckland last Friday to see if they would be the ones to select the key that unlocked the grand prize.

Drawing the keys in the order they had won them, Shona was up first to choose her key with Jono & Ben. 

Then later live on air with Matty & PJ it turned out that Shona had been lucky with her pick as her key was the one to open the door after not one, not two, but three other contestants had each tried unsuccessfully.

Congratulations Shona! We are so happy for you! Watch the amazing moment unfold above.
