The review is required under the DIRA Act 2001(Dairy Industry Restructuring Act), when Fonterra was established. It sets out the rules for supply to other milk companies and anticipates those DIRA provisions being phased out once certain market share thresholds have been met.Commissioner Stephen Gale said “the review will look at whether the regulations are helping or hindering the efficient operation of the NZ dairy industry. To do this we intend to examine how competition has developed since Fonterra was established and what it might look like in the future.”
