The most controversial of the measures is the change to the voting system, which will mean doing away with the current single transferable vote system and adopting a candidate ratification method that will require a board prospect to achieve 50 per cent support.
Wilson said most of the farmer concerns lay around changes to the voting system. "It's a change in the way that we do it, but there is wide acceptance that this represents the best opportunity to attract the best people," he said.
Under the new rules, the board will have seven farmer directors and four independent directors.
Wilson told the Herald last week that getting over the 75 per cent threshold would be a big ask for any organisation. "And it certainly is for our co-operative."
Federated Farmers dairy chairman Andrew Hoggard told the Herald this month that he expected the voting to be close, adding the shift in emphasis from one of voting for candidates to one of ratification of a pre-selected candidates was at the centre of farmer concerns.
"There are a lot of people that like the fact they get to choose the candidates," he said. "It will be bloody close and I would not like to guess which way it goes, but I don't think that it's a given that it will pass."
Internet, postal, fax and proxy voting closed on Wednesday.
