The Royal Commission into historic abuse in care says artificial intelligence used to analyse documents will not review survivors' written submissions.
RNZ revealed this week officials had suggested increasing the use of artificial intelligence when reviewing documents as a way to save money.
A spokesperson for the Royal Commission said they expect to receive around a million evidential documents and manually reviewing each one was not possible.
They said the software was only used to sort and prioritise documents, so they could then be manually reviewed by investigators.
The spokesperson said the documents were encrypted and stored securely.
