NZ Herald

Loaded Language
Headline & Lead 85/100
The headline accurately reflects the article's focus on polling trends but slightly overemphasizes a widening margin, which is nuanced in the body by bloc stability.
✓ Balanced Reporting: The headline presents a clear claim about polling trends but avoids overstating certainty by referencing the 'Poll of Polls' as a predictive model rather than asserting a definitive outcome.
"Poll of Polls predicts who will win election and suggests margin of victory is growing"

Language & Tone 92/100
The tone is largely objective with strong attribution, though some emotionally charged language slightly undermines neutrality.
✓ Proper Attribution: The article attributes claims to a named expert and institution, enhancing credibility and neutrality.

✕ Loaded Language: Phrases like 'skyrocketed' and 'polling crash' inject unnecessary drama into otherwise neutral trends.

Completeness 90/100
The article provides strong methodological context but omits transparency about the nature of private poll sources.
✓ Comprehensive Sourcing: The article explains the methodology behind the Poll of Polls, including use of public and private polls and 4000 simulations, providing strong context.

Te Pāti Māori framed as experiencing a significant and sudden decline in support
[balanced_reporting]: Despite neutral language, the use of 'polling crash' and 'shedded supported' strongly frames the party as failing electorally.
"Te Pāti Māori, after initially rising towards 5%, have suffered a polling crash, shedding supported over the course of 2025"
Labour Party framed as gaining momentum and electoral viability
[balanced_reporting]: While neutral in tone, the repeated emphasis on Labour’s 'steady rise' and status as 'largest party in Parliament' frames it as increasingly effective electorally, even if not in government.
"Labour’s steady rise has not translated into a polling lead for the opposition over the coalition"
National Party framed as losing support but still central to governing coalition
[balanced_reporting]: The article notes National's 'decline' in vote share but balances it with coalition math, resulting in a moderate negative framing of performance.
"the National Party’s vote has declined considerably since the election"
Green Party portrayed as slowly losing ground, though not in crisis
[balanced_reporting]: The article describes a slow, 'imperceptible' decline, framing the party as underperforming but not collapsing.
"The Green Party has slowly shed vote through the parliament. Its decline has been so slow as to be almost imperceptible, but it is now comfortably below the 11.60% it scored on election night"
The article presents a data-driven analysis of polling trends using a credible model, with balanced coverage across parties. It maintains a mostly neutral tone, though some emotive language slightly undermines objectivity. The framing emphasizes bloc stability while the headline suggests growing divergence, creating minor dissonance.
A new Poll of Polls model by NZ Herald and Motu Research aggregates polling data since 2014 to simulate election outcomes. It shows National-led coalition maintaining a narrow majority, despite shifts in individual party support. Vote changes appear to reflect movement within political blocs rather than major realignments.
