The Minister for the Environment says the country's election register will be cleaned up in time for next year's general election.
Dick Roche says he putting a lot of resources into editing the seriously-flawed voters' list.
This includes combining it with the centralised death register to make sure that the names of people who have died are taken off.
Mr Roche says there will be a major push by the local authorities this autumn to get the list right.
“We will have the houses visited once. There will be a knock on the door and there will be a note left behind that we've been around.
“They will be visited a second time and they will be told that we need you to check who's on the register and then there will be a third notification saying that: 'If we don't actually confirm who's living here, you'll be taken off the register.'" he said.
“Everyone will have their chance.”
The minster said at the end of the year everyone will have the chance to check the register and have their names put back on if they have been removed.
