AllPolls.nz charts one number per party: its share of the party vote in a poll, in per cent. Under MMP the party vote decides how the 120 seats are shared out, once a party passes the 5% threshold or wins an electorate. These charts show that share; they are not a seat forecast.
Reading a chart, step by step:
- One line per pollster. On a party page — National, Labour, the Greens, ACT, New Zealand First, Te Pāti Māori — every firm has its own line: Roy Morgan, Curia, Verian, Anacta (formerly Talbot Mills), Reid Research and Freshwater Strategy. When a firm stops polling, its line stops too.
- Zooming. On a timeline, use the slider under the chart, scroll over it, or drag the window. Campaign comparisons keep a fixed range from 91 days before an election to polling day.
- Hover for figures. A tooltip lists every firm at that date with its number. A point between two polls is interpolated and carries one decimal.
- Legend clicks. Click a firm in the legend to hide or show its line — the quickest way to see whether a move is across the board or in one firm's numbers.
- Election marks. The vertical marks are the general elections from 2005 to 2023; the dot on each is the official party vote.
- Highs and lows. A pin marks the highest or lowest share a party has reached, ever or in a recent window. On one pollster's chart the record is that firm's own.
- Download. The camera icon saves the chart as a PNG.
A pollster page turns this around: it shows that firm's latest poll party by party, answering "what does Verian say now" rather than "how has Labour moved". Each chart has a plain table under it with the same figures, which also works when the interactive chart cannot load. There are no coalition pages yet: the next government is formed after the 7 November 2026 election.
