Triathlon New Zealand's high performance boss Graeme Maw has resigned after four years in the role.
Englishman Maw said he believed he had taken the high performance programme "as far as I can".
"After four years of leading change, I feel I have taken the HP programme as far as I can. I recognise that performances and culture are not yet where they need to be, and it is time for someone else to take the reins for the next step," he said.
Maw said many of the operational priorities of the 2020 HP plan had been achieved, such as establishing the national high performance centre in Cambridge, launching a national talent programme around the country, healthy domestic competition and evidence-based parameters for talent development and selection.
"With the framework of this performance pathway in place... I have no doubt that success is not very far away," Maw said.
