NZ Polling Tracker — June to September 2026
Party vote share from every published poll, June through early September 2026, covering the run-in to the 7 November 2026 general election. Hover the chart for exact figures at each poll; click a party name in the legend to hide or show its line.
The Post/Freshwater Strategy's 5–11 June poll is omitted — that house doesn't ask about the Opportunity Party, so it can't sit cleanly on the same axes as the rest.
House effects to keep in mind: Roy Morgan and Talbot Mills consistently show Labour several points apart from each other regardless of when the poll ran — that's a systematic house difference, not the electorate swinging. Opportunity's rise (3–4% in June to 8–9.5% in August) is the one trend that shows up consistently across every house, which is why it reads as a real shift rather than noise.
