In July of last year, William retired as the Chief Executive of the Waikato Chamber of Commerce, following a successful four-year turnaround of the organisation.
"At the Chamber I got to listen to and speak with a vast range of business people from our region, as well as political and business leaders from across New Zealand and the world, telling them all about the great place that this region is.
"My goal is for everyone in the Waikato to feel proud of living and working in this exceptional part of the world. Like you, I want a better future for the Waikato region and us all."
William and his wife Alison live in Claudelands, they have two grown-up daughters and Vespa, their three-kilo poodle/bichon frise.
