The National Treasury Management Agency has notified the Office of the Data Protection Commissioner of a potential data security breach.

A spokesman for the NTMA says the incident occurred yesterday as State Claims Agency records were being removed from the NTMA premises for archiving by the NTMA's off-site document storage provider.

During the removal process SOME of the contents of a small number of storage boxes were dislodged.

The NTMA has confirmed it is currently investigating the incident and a full report will be sent to the Office of the Data Protection Commissioner.

Meanwhile, the Office of the Data Protection Commissioner says it is liaising with the NTMA on the matter.
