One of the National Government's ways to save millions of dollars in health to spend on new services is struggling to proceed, a document obtained by the Labour Party indicates.
Labour is using the letter, written by a district health board chief, to cast doubt on National's spending promises.
Health Minister Tony Ryall has estimated that $700 million can be saved over five years by DHBs sharing many back-office tasks, such as financial management and the purchasing of medical supplies.
Yesterday, he rejected Labour's questioning and said he was confident the savings targets could be achieved.
The Government established the agency Health Benefits Ltd (HBL) to undertake shared DHB functions. The agency describes itself as "critical" to changing the health sector.
