Great People

Viticulture Team Nick Hunter Brenton O'Riley Kevin Morrison Michelle Barry

Great wines start with the land, ensuring its healthy so the vines and wines are packed full of goodness and flavour. To manage we have a great team of viticulturists, who look after our company-owned vineyards and work with top growers ensuring every vine is in peak condition.

NICK HUNTER, Company Viticulturist

Growing up in Marlborough with parents involved in the wine industry Nick Hunter’s future was almost predetermined – just as well he loves the region and the wine industry!  Working in vineyards during school holidays Nick decided he enjoyed working outdoors and growing grapes, and seeing how the fruit progressed through to the bottle.

After completing a degree in horticultural management, from Lincoln University, Nick spent three years managing a hillside vineyard in Central Otago before returning to Marlborough.

Since starting at Giesen in 2013, Nick has held the role of Grower Viticulturist and now Company Viticulturist where he is responsible for the fruit intake for the Giesen range of wines.

‘’We are very fortunate within the Giesen Group to own and manage a diverse range of vineyards within Marlborough. The company owned vineyards, combined with the wider family of talented growers in Marlborough, Hawke’s Bay and Waipara show the true character of place  which provides the strong foundation  for our range of wines.’’

Outside of work Nick loves nothing better than enjoying a glass of Giesen Fuder Sauvignon Blanc with family and friends.


BRENTON O’RILEY, Grower Viticulturist

Brenton grew up on a dairy farm in the Manawatu, but says he was set on getting involved in viticulture from an early age. “I have always had this bizarre passion from a young age that I wanted to grow grapes. I don’t know where it stemmed from, it’s just always been there,”

When he’s not working in our vineyards on grape vines or meeting with grape growers Brenton loves nothing more than spending time in the region’s great outdoors enjoying his favourite leisure activity – fishing in the Marlborough Sounds.

Brenton was Marlborough’s Young Viticulturist of the Year in 2014 and a finalist in New Zealand’s Young Viticulturist of the Year 2014.


MICHELLE BARRY, Assistant Vineyard Manager

Before moving to New Zealand from her native Ireland in late 2015, Assistant Vineyard Manager Michelle Barry had never seen a vineyard! Knowing the vital role Michelle plays keeping Giesen’s vineyards in tip top condition it’s hard to believe. She seems born to the task.

Once you know she completed a BSc in Environmental Science and a Master of Science with Research in Soil Chemistry, it all makes sense. While Michelle may have stumbled into viticulture by choosing to work in horticulture on her working holiday to New Zealand she loves it, saying it’s the perfect blend of nature, science and art.

When she’s not toiling in the vineyards, Michelle makes the most of all that Marlborough offers. She plays rugby for Moutere RFC, adores horse riding, hiking and outdoor activities.
