Our founding directors

founding directorsHYC was founded in 1995 in Auckland by David Hill and Adrienne Young-Cooper, who saw a place in the market for a consultancy focused on environmental policy analysis and preparation.

They decided that their mutual values and complementary strengths would form the perfect partnership! David’s career had started out in public policy in the 1970s and over time he developed an expertise in resource management. He was a qualified social scientist with a Bachelors and Masters Degree in Social Anthropology.

Adrienne graduated in 1978 with a Master of Science degree majoring in Resource Management. She had over 15 years of planning and resource management experience both in local government and as a consultant when HYC was founded.

While building up HYC, they both pursued a range activities, with Adrienne holding numerous board memberships and company directorships while David was chair of the Auckland Museum Trust Board and prior to that, the Auckland Conservation Board.

Adrienne left in 2010 to concentrate on her role as a company director. David remained a couple more years before stepping aside after 17 years in March 2012 to concentrate on his work as an independent hearing commissioner.

Adrienne and David worked hard to make HYC the successful company it is today. We have retained the name of the company that they founded as a mark of respect of their contribution to resource management in New Zealand.
