Pippa Wetzell is taking over from Alison Mau as a co-host on Fair Go.
The former Breakfast presenter is stepping into the role with Mau set to join Greg Boyed and Jesse Mulligan as a presenter on TVNZ's new flagship current affairs show Seven Sharp.
She was "thrilled" to be joining the long-running show.
"I'm looking forward to upholding the standards and responsibilities that Fair Go has become known for," she said.
Wetzell has been reading One news at 4:30pm after returning to TVNZ from maternity leave.
