Academic career

After a Ph.D. from Lincoln College (awarded through Canterbury University due to Lincoln's status at the time) Edmeades worked for the Ministry of Agriculture and Fisheries at Ruakura and then AgResearch after the 1992 reorganisation which created Crown Research Institutes. He left in 1996[1] and now runs his own consultancy, agKnowledge Ltd.[2]

In the 2013 Queen's Birthday Honours, Edmeades was appointed an Officer of the New Zealand Order of Merit, for services to agriculture.[3][4][5]

Litigation

In 1989, while working for the Ministry of Agriculture and Fisheries, Edmeades appeared on the TV show FairGo expressing the view that seaweed-based Maxicrop didn't work.[6] Legal action was initiated by Maxicrop's New Zealand distributor, the Bell-Booth Group. In Bell-Booth Group Ltd v Attorney-General the Court of Appeal found for MAF and FairGo[6] after 'the country's longest civil court case.'[2]
