Dunedin was likely to benefit through the use of innovative digital technologies, he said.
The former Dunedin resident was yesterday shown around the Living Hub at the Dunedin City Library by Dunedin North MP David Clark.
Mr Robertson was also given a demonstration of six digital projects, including two business start-ups which have been funded, at least in part, by telecommunications company Chorus, after Dunedin's win in the national Gigatown competition in 2014.
He also tried virtual reality devices, funded by a $20,000 community grant, which enable painting and drawing to be undertaken in four dimensions through a virtual learning community, Hive Dunedin.
Mr Robertson said Labour wanted to establish a new centre of digital excellence in Dunedin, and the new technologies clearly had a significant role in boosting regional development.
