Voting closes on March 15, ahead of the organisation's annual meeting in Timaru on March 21.
Two resolutions would be presented at the meeting, including a proposed increase in chairman and director fees.
At a meeting in November, the directors independent remuneration committee discussed director workload and reviewed independent advice in director fee increases across other organisations.
The committee noted the increasing workloads for directors as climate change, water policy and Mycoplasma bovis required significant additional time and expertise.
The directors' independent remuneration committee had recommended the chairman's fees be increased from $69,000 to $70,000 and directors' fees increased from $33,350 to $34,000.
The board supported the recommendations and cited increasing concerns about the time commitment required for each director to fully represent their region, farmers nationally on key policy issues and keeping up to date with a faster moving regulatory pace of change.
That had implications for each director's own farming business and was an area the board would "carefully consider" this year.
