Embattled ex-Green MP Darleen Tana has broken her silence after backing away from the party.

Tana spoke to 1News in her first sit-down interview since she quit the Greens - but she hasn't confirmed any plans to leave Parliament altogether. 

ZB political editor Jason Walls says it's unlikely Darleen Tana will step down.

"She says she's going to be making a decision soon. My read on all of this - it sounds like she's not going anywhere. She keeps coming back to the values that she brings to the table in terms of being an MP."
