Three experts have been appointed to carry out a sweeping review into RNZ's editorial processes and policy following pro-Russia edits being made to wire stories sourced from Reuters and the BBC.

RNZ board chair Jim Mather announced this morning the investigation will also cover the circumstances surrounding the edits, and the handling of a complaint made by the Ukrainian community about the stories.

All this has been given a timeline of four weeks.

Media commentator Andrew Holden spoke to Jimmy Ellingham.
