"However, we are not willing to jeopardise the integrity of the contest just to make it more of a reality drama and there has been no willingness on behalf of the networks to embrace what is still the most prestigious agricultural competition in the world," he says.
"It continues to be a wonderful vehicle for showcasing excellence and the talent of young farmers in this country and in our opinion is a slice of primetime television that all New Zealanders need to relate to."
However, Mr Rabbidge praised NZ On Air for its ongoing support and encouragement with funding, but said NZ Young Farmers could not afford to fund the entire production itself.
"NZ On Air has always tried to support what we are doing but it is a great disappointment that we cannot get television networks to screen what is an extraordinary event with courageous characters that exemplify the Kiwi spirit."
With no presence online or on television Mr Rabbidge said the contest would be forced to use social media as the main platform.
"And while that is not the scenario we wanted in our 50th contest season, we will move forward and embrace new technology platforms." NZ Young Farmers chief executive officer Terry Copeland said he was saddened by the networks' decisions and believed they were missing an opportunity to profile incredible young finalists who often moved on to become New Zealand thought leaders.
"It is particularly difficult to accept that TVNZ, who are charged with showcasing New Zealand content, no longer see value in what is still an iconic piece of our history."
