A post office box and telephone line are to be set up to allow people with information on people abducted and killed by the IRA to share it with the Independent Commission for the Location of Victims' Remains (ICLVR).
The nine people who the IRA admit to having killed and buried in unknown locations are known as the "disappeared".
The PO box and confidential phone line are part of a series of measures announced today by the Minister for Justice and Law Reform Michael McDowell in conjunction with the British government and the ICLVR.
The other measures include the hiring of a forensic expert and the establishment of a project team to work with the commission and non-invasive surveys on all suspected gravesites, including examinations of all relevant mapping, forestry records and aerial photography of sites at the time for comparison with current imagery and mapping by imagery analysts.
DNA samples will also be collected from the closest biological relatives of all victims whose bodies are yet to be recovered. Any surviving medical and dental records will also be secured.
The measures announced today are the result of a review conducted by a forensic sciences investigative consultant of the work carried out to date and an assessment of what further steps could be taken to recover the bodies.
The victims' families were briefed earlier today by the ICLVR.
Mr McDowell said both governments remain committed to doing all that is "reasonably possible" to aid the location of remains. However he warned against unrealistic expectations, particularly given the number of unsuccessful excavations in previous years.
In line with the report's recommendations, physical excavation of gravesites will now only be undertaken if and where the commission assesses there to be a good prospect of successful recovery of remains.
Mr McDowell pledged that the ICLVR will continue to be given all the backing it requires in its quest to recover the bodies, while stressing that responsibility for the plight of the families lies with those who carried out the killings and burials.
