This year we are delighted to have some excellent speakers presenting on a variety of topics, among them, the dynamic Sean Colgan, CEO International Materials and former Olympic Rower, and Jane Arnott, Director Ethics Conversation who is an engaging speaker, joining us this year in Tauranga after being set to visit Nelson last year before the conference cancellation.

From Infometrics, we have principle economist Brad Olsen. He doesn’t have a crystal ball about the future of the building industry from an economics perspective, but his insight and experience is a close second.

David Soper is the Senior Regional Facilities Manager for Colliers, bringing us a wealth of knowledge and experience in this area.

Mark Irving, Priority One will be taking us through the Tauranga CBD Blueprint project. As the Project Manager, Mark will be presenting on the topic, followed by a walk through the CBD, so make sure to leave your heels at home.

And last but most definitely not the least, Gareth Wallis, Tauranga City Council GM: City Developments & Partnerships will be providing the keynote address.
