There's pressure on Metiria Turei to quit, this time from the former boss of Work and Income.

In her latest revelation about her benefit fraud, the Greens co-leader has admitted lying about where she lived - in order to vote for a friend who was a candidate in a different electorate.

It has also been revealed she lived with her mother for a period while she was claiming a benefit.

Former WINZ chief executive Christine Rankin told Mike Hosking Ms Turei is no longer fit for the job, and needs to face prosecution.

"This is a litany of lies, and how can she be trusted and how do we know what the truth actually is 25 years down the track?"

"She creates her own truth at the moment, it's a convenient truth, but who knows what the real situation is, but she's a liar. It is criminal activity."
