Take the data

Every poll, the statutory threshold, the known limitations and the source revision — exactly as the site reads it.

One row per poll, one column per party. A party column is empty where that pollster did not report it — never zero.

Each party's 2025 annual return: Part A total, the named donors where they reconcile, and how each return was read.

One row per named donor (donations over $5,000), for the parties whose donor list reconciled to their printed Part A total.

Every MP's declared pecuniary interests across the 14 categories (parliamentary paper J.7), as they wrote them.

One row per declared interest: the member, the category, and the entry verbatim.

Each party's position in eight areas as a verbatim quote with its source, or absent where not stated.

One row per party per area. The quote is empty where the party does not state a position — the denominator is explicit.

Parliamentary Service travel and accommodation, by quarter and by member.

One row per member per quarter. Empty where a category was not reported — never zero.

Department of Internal Affairs ministerial travel, by quarter and by minister.

One row per minister per quarter, published separately from MP travel because it is a separate bill.

Google political-ad spend for New Zealand from the Ad Transparency bundle, by party and top advertiser.

Meta (Facebook/Instagram) political-ad spend from the Ad Library snapshot, by party and top advertiser.

One row per platform per party. Google and Meta are kept as separate rows — they are different platforms, not one total.

The inputs to the seat projection: the 120-seat house, the locked electorates per party, the Monte Carlo seed and the scenarios. The projected ranges are computed from the polls.

The electorate seats each party is taken to hold going in, before the list-seat allocation.

What each file contains, the source, and the licence.
