According to the department, the employment in benefit delivery will result in an extra inward investment of almost £35 million annually. There are 270 jobs in Derry, 116 in Ballymena, 27 in Ballykelly, and 595 in Belfast.
It's a part of the UK Department for Work and Pensions' (DWP) service delivery expansion. Communities Minister Gordon Lyons spoke of a significant uptick in the regional economy.
"It is testament to the quality of service being delivered in my department," he stated.
"At present, over 3,600 within the department are currently engaged in delivering services for DWP."
This essential work is carried out from locations in Ballykelly, Belfast, Derry, and Ballymena.
"On a daily basis they are making a vital contribution enabling residents across Britain to access welfare, pensions and child maintenance programs.
"I am pleased to announce a strengthening of this long-standing relationship with the creation of a further 1,000 jobs over the coming months, offering a majority of permanent full-time roles and opportunities across Northern Ireland."
"I was delighted to visit Northern Ireland for the first time as a DWP minister to see the positive impact the DfC teams are delivering on the ground," DWP Minister for Transformation Andrew Western continued.
"Bringing 1,000 new service delivery jobs to these four areas of Northern Ireland will be invaluable to the local economy through providing more jobs for people and in delivering a key service for our customers."
