Metiria Turei isn't the only reason the Green Party has slipped in the polls.
The party's dropped from 13.3 per cent support to 8.3 in the latest Newshub-Reid Research poll.
It comes as Ms Turei resigned after admitting benefit fraud.
Director at political and public relations firm Piko Consulting, Stephanie Rodgers told Nadine Higgins initially when Ms Turei admitted the fraud, the party went up in the polls.
"I don't want to get too hung up on whether this fall in the most recent poll was just about Metiria because we also need to remember we've got the Jacinda effect rolling out."
She said Labour's taken votes off New Zealand First and the Greens.
"Both of those parties will have been holding a lot of votes of people who were Labour leaning but didn't really know which way they would go or wanted to ensure they had a strong coalition partner."
