Board chairman Paul Reynolds said Mr Stuart’s "unwavering leadership", navigated Ospri through a transformative strategic phase and a significant period of organisational growth.
During Mr Stuart’s tenure, he expertly restored Ospri’s standing as a trusted partner in the biosecurity network and strengthened its role as an integrated disease management agency, Mr Reynolds said.
His accomplishments include enhancing relationships and trust with shareholders, iwi and Māori, stakeholders and other predator management agencies, managing a significant disease outbreak and driving down the number of Tb-infected herds to its lowest level on record.
He decentralised Ospri’s operating model and built a strong organisational capability and workplace culture and led the transition of the M. bovis Programme to Ospri under a Government Industry Agreement.
Mr Stuart was also instrumental in the development of technology infrastructure which would deliver tangible benefit to farmers in the future, he said.
"Undoubtedly, Mr Stuart leaves Ospri in a more resilient and strengthened position."
The board would promptly initiate the recruitment process for a new chief executive.
Mr Stuart’s final date at the organisation would be determined to facilitate a seamless transition for the incoming chief executive, Mr Reynolds said.
