The DHB has previously referred questions about how many people were in each priority group to the Ministry of Health.
When asked how many people were in each group, Southern DHB vaccine rollout co-leader Karl Metzler only gave an estimate that there were 100,000 people in group 3 in Otago and Southland.
"Yeah that's like how long is a piece of string," he said.
"Off the top of my head I don't have that data because we're still really working our way through group 3 and because of supply constraints and the new booking system, it's really difficult at this stage to track those numbers exactly."
