Silver Fern Farms Co-operative Ltd is seeking feedback from shareholders on proposed amendments to its constitution, which include increasing the number of directors on the board.
At the co-operative's annual meeting in April, chairman Rob Hewett signalled a review was under way.
In an update to suppliers, Mr Hewett said the board had reviewed the constitution to ensure it was "fit for purpose'' following the partnership with China's Shanghai Maling, which was completed in December 2016.
The proposed refinements covered governance development, appointed supplier directors and limits on the tenure of directors, as well as farmer-elected director eligibility and voting eligibility.
It was proposed to increase the size of the co-operative board from a maximum of eight directors (five farmer-elected directors and three board-appointed directors) to a maximum of 10 (up to six farmer-elected directors and up to four board-appointed directors).
