Rotorua Green Party candidate Richard Gillies says he is disappointed two of the party's MPs have quit caucus, but supports under-fire Metiria Turei remaining as co-leader.
Kennedy Graham and David Clendon quit in protest this week over Ms Turei's refusal to step down, saying her position was "untenable".
The move follows Ms Turei admitting lying to Work & Income while she was on the Domestic Purposes Benefit, and giving a false address to the Electorial Commission in the 1990s.
The two will stay on as MPs until the election, but will not take part in any caucus events or campaigning.
Mr Gillies said he was disappointed Mr Graham and Mr Clendon had withdrawn but he respected their "right to dissent" and had "nothing but appreciation for their hard work and contributions as MPs over their years of service".
