The controversial electronic voting system is still costing the taxpayer.
€400,000 is to be spent on trying to prove to the public that the system is safe in time for the next election.
The Department of the Environment says it is spending €97,000 on a fresh assessment of the controversial system, while the Commission on Electronic Voting has decided to spend €280,000 on three separate tests.
This is on top of the €52m already spent on electronic voting machines, which are now being stored at an annual cost of more than €650,000.
