Health Minister Dr David Clark has confirmed the new Dunedin Hospital will be built on multiple blocks in central Dunedin, including all of the former Cadbury factory site.
The site will be made up of the western side of the Cadbury site, together with the block bordered by Hanover, Castle, Cumberland and St Andrew Sts.
However, rather than including only part of the Cadbury site, it will include all of it as well as the Cadbury car park.
The plot includes land occupied by the former Cadbury factory, Work and Income, Vehicle Testing NZ and a cluster of other businesses, as well as a University of Otago hall of residence.
Cadbury ceased making chocolate at its Cumberland St site in March, although the Cadbury World tourist attraction remains open, and consent has been issued for it to move to the other side of the Cadbury site.
