The Health Ministry says work to ensure doctors know the best treatments for common disorders will continue, despite the loss of a key group.
The independent Guidelines Group has been taking steps towards liquidation since learning it is to lose the bulk of its government funding in June.
The ministry says it acknowledges the valuable work provided by the group and worked with it to see if it could continue.
The ministry also says it has now been advised that the group intends to go into liquidation, but that that won't be the end of its evidence-based work.
It says that will continue in agencies such as the Health Quality and Safety Commission, the National Health Committee and Pharmac, with clinical networks playing a greater role.
But the medical director of the Society for the Study of Diabetes, Paul Drury, says the Guidelines Group members could analyse and adapt international literature in recommendations that in some cases were world-leading, and clinicians won't have the time.
