John Barker is the Principal of John Barker Law. He qualified as a lawyer in 1992. After several years working in banking and finance litigation for a major New Zealand law firm, John turned his legal focus towards food and beverage - specialising particularly in the wine industry. 

John has accrued more than 20 years’ experience in the international food and beverage sector specialising in law and policy roles within private legal practice, government and industry organisations. For 10 years, he was General Counsel and General Manager Advocacy and Trade for New Zealand Winegrowers, the national wine industry association. In that role he has led the wine industry’s involvement in such decisive policy developments as the enactment and implementation of the Wine Act 2003 and the Geographical Indications (Wine and Spirits) Registration Act 2006. Prior to that, he worked for the New Zealand Food Safety Authority and Freehills in Australia in the areas of wine law, trade marks and anti-counterfeiting.

John’s prize-winning doctoral thesis dealt with the international regulation of the wine industry. He has subsequently taught an LLM course on wine law and contributed to numerous publications including the recently released Global Wine Regulation and the upcoming Oxford Companion to Wine 4th Ed.  

John has held numerous national and international leadership roles including President of the Law and Economy Commission of the OIV, Industry Chair of the World Wine Trade Group and the APEC Wine Regulators’ Forum, Executive Officer of the New Zealand Grape Growers Council and the Wine Institute of New Zealand and Chair of The Tomorrow Project Inc. He was appointed a Chevalier de l’Ordre de Mérite Agricole by the Republic of France for his role in the OIV.
