Corey Hall:

Corey grew up around the beaches, orchards and vineyards of West Auckland. After gaining a BSC at the University of Auckland Corey went on to the University of Adelaide and gained a Graduate Diploma in Oneology. Corey has worked as a winemaker in Australia, France, California and in New Zealand at Matua Valley Wines (where he worked for 10 years, rising to the position of Chief Winemaker).

He resigned from this position in 2005 to start his own business making wine and together with his wife Megan established The Studio Wine Co (GEM). A few years later in 2008, they established a contract winemaking business with a Marlborough based business partner and released another brand Harwood Hall.

In addition to winemaking, Corey spends time judging both in NZ and Australia. He has spoken regularly on sponsored radio shows and has been promoted by his peers to the position of Senior Judge, judging at the New Zealand International Wine Show and has been Senior Judge and Panel Chair at the Australian Small Winemakers Show.


Corey & Megan Hall established The Studio Wine Company in 2005 from which they produce their label Gem. Based in West Auckland, they select small parcels of fruit from vineyard sites throughout New Zealand. With a hands-on approach to the winemaking, they spend a significant amount of time in the vineyards and winery to make sure they get the results they want, at every stage of the process.
