Dave Cull was born in Invercargill in 1950 and attended Southland Boys High School before moving to Dunedin. He completed a BA in Political Science at the University of Otago and worked part time as a teacher and in the building industry.
After extensive travel around the world, he returned to Dunedin and commenced employment with TV One as a presenter of home improvement and DIY shows. He began writing in these areas as well and has published several books, on subjects as diverse as icebergs, weather and wine, and training manuals as well as writing for newspapers, magazines and radio. When his work no longer involved extensive travel, he took the opportunity to stand for the Dunedin City Council in 2007.
Once elected to the Council, Dave was appointed Deputy Chair of the Economic Development Committee where he was instrumental in the development of the Dunedin Digital Strategy. He believes that digital technology is part of the essential infrastructure of the 21st century.
Dave stood successfully as mayoral candidate in 2010.
