The Department of Health in NI employs 920 staff in agencies or arms length bodies on wages of over £100,000.
The figures were revealed in answer to a question from DUP MLA Jonathan Craig to the Department of Finance and Personnel (DFP).
He asked how many staff employed by agencies attached to each Stormont department earn wages over £50,000.
Finance minister Sammy Wilson revealed 3,430 staff earn £50,000-£100,000 and 967 earn in excess of £100,000.
Mr Wilson also revealed the department of health has the biggest wage bill employing 2492 people on salaries of £50,000-£100,000.
Arms length bodies are organisations such as health trusts or education and library boards which operate with varying degrees of independence from goverment.
In its response DFP confirmed that Mr Craig's question was one of a number requesting information on salaries paid to department's arms length bodies.
The department of justice, which was established in April 2010 has the second highest wage bill after the department of health.
It employs 288 staff in agencies within the £50,000 to £100,000 bracket whilst 11 are earning more than £100,000.
The department of education employs 253 staff paid between £50,000 and £100,000 and two on £100,000 plus.
The response from DFP acknowledged that the interest in public sector salaries was likely to continue while the Executive considers the impact of the reduction in funding.
