Keynote speaker Oscar Aliaga Ortega has been involved in the Chilean cherry business since 1993 and has seen the industry evolve, grow and transform into the largest southern hemisphere cherry producer.

Not only is he a teacher in the Agronomy Faculty of Pontificia Universidad Católica de Valparaíso, he also works as a cherry consultant for around 40 growers (Chile and Argentina), and several exporters including Dole, Geofrut and Greenvic. 

Somehow Oscar also finds time to grow cherries and has over 26 hectares planted in several cherry varieties, so he can practise what he teaches. No doubt this allows him to try out his own theories while gaining first-hand experience and perspective on the issues and pressures that growers face.

Mike Petersen


Mike Petersen

Mike is New Zealand’s Special Agricultural Trade Envoy (SATE) and has held this role since July 2013. This unique role was established by New Zealand ministers in close consultation with New Zealand’s agriculture sector – to bring a farmer’s perspective to international trade in food and agriculture, and to build partnerships with farming organisations and companies offshore. 

While not a government official, Mike is appointed by ministers to bring a sector view to discussions, that is informed by his wider contact with New Zealand’s agriculture and horticulture producers. Drawing on his considerable farming and private sector experience, Mike works to promote a greater understanding of New Zealand’s agricultural trading interests, including dairy, meat, wool, horticulture and wine, from the perspective of a practising farmer. 


Tim Cadogan

Tim Cadogan

I feel privileged to be the Mayor of this fantastic place and honoured to serve the people of Central Otago. I am married to Linda and between us, we have four wonderful grown-up children and one grandchild.

Immediately prior to becoming Mayor I had three jobs, being a lawyer specialising in Criminal, Family and Employment Law, a Disputes Tribunal Referee and a Trustee of Central Lakes Trust. Prior to being a lawyer, my wife and I owned a retail business in Alexandra for a short period of time and prior to that I worked in radio, primarily in Alexandra, for 12 years. 

Very important to who I am today is the role I played when I first came to the region; being a solo father on the benefit with two pre-school children, followed soon after by many years raising those children on one income. Those times left me always conscious of how hard life can be, both financially and in other ways for some of the people in our region.

Peter Mortimer has been with Fruitfed Supplies through various roles around New Zealand for 34 years. The merger of PGG and Wrightson in 2005 led him to take on the Fruitfed southern regional manager’s role.

In 1993, with the rapid growth of the grape market and increased activity in wine companies building wineries in Blenheim, Peter saw an opportunity. To provide a service to this sector, something new to Pyne Gould Guinness, he negotiated with one small supplier of winery ingredients from Wellington to support demand in Blenheim. The winery sector is now a significant contributor to the PGW business and Peter is responsible for its success as national product manager – winery.

Peter was appointed key account manager for Fruitfed Supplies in 1993, covering all horticulture sectors. A member of the management team, you could say that Peter is fairly institutionalised at Fruitfed Supplies, with his vast knowledge of the horticulture industry, across a wide range of categories.
