The new Antrim and Newtownabbey council will adopt a traditional committee system during the shadow period.
Under the Local Government (Northern Ireland) Act 2014, councils can choose from three governance models - Executive Arrangement; Committee Arrangements; or Prescribed Arrangements.
Chief Executive Jacqui Dixon told councillors at the inaugural AGM of the new council, that there had been prior discussions with council officers and the group leaders of the political parties regarding the governance model.
She advised that it was recommended that a traditional committee system be adopted, with four committees set up, which was subsequently agreed by the elected members.
It was also agreed to have four committees - Governance Arrangements & Constitution for the New Council Committee; Policy, Resources & Service Convergence Committee; Community Planning & Regeneration Committee; and (Shadow) Planning Committee.
Fifteen members will sit on each of the first three committees, while there will be 20 members sitting on the planning committee.
The allocation of positions to the committees will be decided by the parties using the Quota Greatest Remainder formula.
The council will nominate members to these committees at the next meeting on June 26.
