The Wakatipu Health Trust has announced it will wind up after more than eight years in favour of the new Wakatipu Heath Reference Panel.
Trust chairman Craig Benington said he and fellow trustees saw no need to have two groups championing the same issues.
"This will only create confusion, dilution of effort and potential conflicts. Accordingly, trustees have agreed to wind up the trust, allowing the mayor's new group to assume the ongoing responsibilities."
Mr Benington said the independent, not-for-profit registered charitable trust raised and spent more than $750,000 to enhance public health services in the Wakatipu.
"A major objective for the trust for the last few years has been achieved with the recent NHB [National Health Board] report acknowledging that the Wakatipu has been underserviced by successive DHBs [district health boards].
"The NHB has now given clear instruction that this is to be corrected and it is very pleasing for the trust to obtain vindication from the NHB."
Mr Benington, a WHK partner, said he and fellow trustees Maria Cole, Dr John Hillock, Helen Stevens, Dr Neki Patel and Kristian Summerfield, would work with the Queenstown Lakes District Council to hand over assets and responsibilities.
The council as facilitator received six applications for the two community representative seats on the new Wakatipu Heath Reference Panel which is being formed.
The panel was one of the recommendations made by the NHB panel to the Southern DHB to act as a Wakatipu health champion and watchdog for the DHB.
The NHB recommended a council representative chair the panel and membership was to include one primary care clinician, one secondary care clinician, at least two community representatives and a DHB representative, who would collectively liaise with the recommended "tier two" DHB manager responsible for health services in the Lakes and Central Otago districts.
