A short video of Russell's Maioha family spreading rocks on a walking track was enough to book them a place in a television series.
Carpenter Gavin Maioha, wife Angela, daughter Grace, 14, and son Kade, 12, competed in the XVenture Family Challenge shot on the grounds of the Eagles Nest luxury resort in the Bay of Islands.
In the series, host Simon Barnett sets 16 families a range of diverse team challenges such a flying a drone and the winners get$25,000 cash.
The series started showing on Three on February 11 and will run every Sunday for eight weeks. Each week, four families compete in three different challenges. Two families go through to the next round and two return home.
The 16 families were chosen from a major search across the nation including 50 regional events, from schools, sports clubs, performing arts groups, associations and local councils.
Mr Maioha said the principal of Russell School, William Fuller, urged his family to make a video that would be submitted to the television producers.
"William is the head of the Bay of Islands Walking Trust and he had an idea of getting us to spread rocks on the Okiato to Russell Walkway and he videoed it.
