That report showed more than $1billion dollars in savings could be realised from a rationalisation process that included the four largest companies: Silver Fern Farms, Alliance Group, ANZCO and AFFCO.
In 2014, farmers backed a remit from MIE seeking Beef and Lamb New Zealand cash to back its quest for industry reform.
But earlier this year, they rejected two remits put forward by MIE which were seeking to replace the two processor representative positions on the board of Beef and Lamb New Zealand with its own directors.
It also wanted Beef and Lamb New Zealand to endorse and fund all costs incurred by it to "continue developing and implementing the savings and positive opportunities" identified in its report.
This week, Mr McGaveston said it had been disheartening that co-operative directors, Beef and Lamb New Zealand, Federated Farmers, the Government and organisations farmers trusted to show leadership and direction had fought to stifle all MIE's efforts to create a bright future for New Zealand meat farmers.
Farmers invested in the Pathways to Long Term Sustainability Report and should have expected to have their investment enhanced by embracing the opportunities identified.
"Sadly the anti-reform campaign prevailed, not just within farmers' very own elected organisation, Beef and Lamb New Zealand, but across the underbelly of vested interest groups that dominate the sector," he said.
A large percentage of MIE-endorsed directors "reneged on all their core values and pre-election promises" and "did a total backflip" betraying the people that put them there, he said.
Removing the "competitive destructive model" in market would provide long-term benefits to to all farmers, while passing control of New Zealand's processing/exporting sector to foreign interests would be an "unmitigated disaster" for red meat farmers.
