Over 250 jobs could be lost in the centralisation of DVLA services.
The current plan to transfer key responsibilities to Swansea would result in job losses in Northern Ireland, it is feared.
Further job losses across the UK could also result from current intentions to move more systems to an online platform, endangering local offices.
It is suggested that the changes would make things simpler for the public while also being cheaper for the government to run, but East Londonderry MP Gregory Campbell has disputed this.
“The government are not targeting an under-performing agency to make savings as the DVLA is self-financing and produces a significant operating surplus,” he said.
“There are also other work opportunities which could be done more cost effectively in Coleraine.”
Centralisation plans hit a stumbling block when there were met with industrial action during 2012.
Northern Ireland’s Environment Minister Alex Attwood, who backed these strikes, is to hold talks with the UK Transport Department in an effort to protect the jobs at risk.
Attwood MP has previously said that he has been assured than no decision like this would be made without first consulting him.
A representative of the Northern Ireland Public Service Alliance has referred to the centralisation as an axe that had been hanging over the Coleraine staff since 2011, and that Attwood would have a “tough job” persuading the government to go down a different road.
