The public consultation stage of the government's review of legislation governing Fonterra and the $8 billion dairy industry is due to start in October.
The Ministry for Primary Industries which is leading the review said it expected formal consultation to take place over October and November, with policy recommendations made to government early next year.
Terms of reference for the review were published in early May. The review will consider the effectiveness of the Dairy Industry Restructuring Act 2001 (DIRA) and its impact on the industry.
It is expected to spur changes to the legislation next year.
An MPI spokesperson said meetings with affected industry stakeholders were under way to assist the ministry in developing a formal public consultation document.
