Director General of Health Dr Ashley Bloomfield has been in charge at the Ministry of Health during the Covid-19 pandemic, and now he's leaving his post - one year early.
At the same time, the country is embarking on a dramatic reshaping of its health system.
At a media standup yesterday, Dr Andrew Old, Deputy Director-General of the new Public Health Agency, paid tribute to Dr Bloomfield.
During his tenure Dr Bloomfield was something of a cultural phenomenon.
He spoke to Susie Ferguson.
