Mitch Collins


Pink & White Geothermal Gin

What started as a shared geothermal distillery dream a couple of years ago in a Lynmore garage is fast becoming a reality. Mitch, with Distiller Kurt Matthews and Brad Christie, is about to launch Pink & White Geothermal Gin in Rotorua.

With a lot of local charity, advice and support along the way, we have remained lean and have had a few delays along the way as with any startup.

Mitch is no stranger to the geothermal regulatory environment and for his sins, lived for a few years with Jeremy O'Brien and a Siamese cat named Stompy in London.

Contact Energy

Craig Stephenson leads Contact’s drive to develop alternative (i.e. non electricity generation) uses for geothermal resources – including the direct use of geothermal energy in industry and commercial activities and minerals extraction.
