The Greens are feeling the impact of last week's outburst in the House by MP Julie Anne Genter.
The newest Taxpayers' Union-Curia poll shows the Party has dropped 4.4 percentage points, to 10.2.
National is holding steady at 37.3 percent - and with the support of ACT on 9.4 and NZ First on 5.5, the Coalition Government would remain in power.
ZB political editor Jason Walls says this coming week is a recess week for Parliament, which means Genter won't be resurfacing for another few days.
