Director General of Health Chai Chuah will quit the role early, referring to "controversy" over his time in the role and the need for a new person for the role.
In a statement, Chuah – who was strongly criticised by Labour when it was in Opposition - said he had been considering for some time that the health system needed a new person to take it forward.
He always believed the health system needed to tackle the challenges ahead as one team and while progress was made with the release of the NZ Health Strategy "it has not been without controversy in the system".
"At this time it is increasingly important for the sector to operate in a unified way if we are able to accelerate and further embed the gains we have already made.
For that reason I have decided to conclude my time early."
Earlier this year, Chuah came under attack from Labour and its health spokesman – now Health Minister – David Clark over Chuah's management of the health sector following an embarrassing Budget blunder that saw $38 million wrongly allocated to DHBs. That prompted State Services Commissioner Peter Hughes to get involved and rebuke Labour for its public attacks on Chuah.
