Nesbitt said while the additional £100m from the executive was “welcomed”, his department was still working to find the rest of the funding.
In a statement on Friday, Nesbitt said his department was continuing “to work in good faith with health unions and professional bodies”.
“Talks are continuing as we acknowledge and respond to their concerns within the regrettable financial constraints we face,” he said.
“I very much value the ongoing constructive engagement with the health unions, particularly in terms of identifying and exploring any potential options and common ground, as we seek to work through these difficult issues together.
“We anticipate further discussions next week,” Nesbitt said.
