A bid to save the Cadbury factory in Dunedin is being unveiled today.
Jim O'Malley, a Dunedin city councillor, is trying to raise $20 million to keep the factory open on a portion of the site.
The Dunedin City Council is not involved in the bid.
O'Malley's plan is to run a share offer aimed at the public as well as business. But before launching any share offer, he has organised a two-week pledge period to gauge interest.
If there is little interest, he said the plan would be dumped and the "lights will turn off in March".
