He was unable to discuss other grievances because they were too specific and would lead to the person being identified. "They are real and they are disgraceful.
"I challenge them to say how many of those personal grievances remain unresolved today. It is time for the DHB to walk the talk when it comes to a no-bullying approach," he said.
The DHB late yesterday afternoon told Bay of Plenty Times Weekend nine personal grievances had been lodged with the Employment Relations Authority from 3000 staff.
National's candidate for the Bay of Plenty, Todd Muller, said his personal view was that the doctors and nurses at Tauranga Hospital did a fantastic job and the issues Mr Horan raised were an internal matter for the DHB.
Another speaker at the forum, Labour's Tauranga candidate Rachel Jones, said: "I personally have not heard of any of these stories coming out of the DHB."
Labour's Bay of Plenty candidate and school nurse Clare Wilson said her knowledge of how large organisations handled personal grievances was that there were strict rules about disclosures until the cases were resolved.
The process was really awkward and never pleasant. "Personal grievances are, by their nature, quite emotive."
New Zealand First's Tauranga candidate Clayton Mitchell did not support Mr Horan's bid for the information.
DHB chairwoman Sally Webb said the board ran anti-bullying programmes and personal grievances had not come to the board as being of major concern to management
Ms Bingham said all complaints of bullying were fully investigated and managed as per the DHB's zero tolerance policy and the requirements of the Employment Relations Act.
