The proposed mega merger between NZ Dairy Group (NZDG), Kiwi Co-operative Dairies and the NZ Dairy Board (NZDB) was attacked at the eleventh hour yesterday, as a consortium of eight dairy farmers and seven professionals launched a campaign to derail the deal. The GEA Better Dairy Deal LE group believes that an alternative industry structure will prove more beneficial for the farmers, and has set up a website and posted out documents expounding its views.
