Radio New Zealand has confirmed changes to its Morning Report programme.
Simon Mercep will follow his co-host and step down from the show, when Geoff Robinson leaves in April.
Mercep moves to a revamped afternoon show and current host Jim Mora joins Mary Wilson on evening show Checkpoint.
Auckland-based Guyon Espiner replaces Robinson on Morning Report and is expected to be joined by Wellington journalist Susie Ferguson.
Radio New Zealand is also working on a revamp of the Radio New Zealand news gathering processes, according to a well-placed source.
