Publication and collection notes

These notes distinguish additions, source improvements and unresolved evidence. Earlier releases remain part of the record.

Information update · 1 October 2026

Added 38 original summaries of party proposals across the existing five policy topics. Announced measures remain distinct from enacted laws or demonstrated outcomes. Undated policy pages retain an unknown publication date and a separate observation date.

Added the Electoral Commission’s registration entries for Free Palestine and Te Tai Tokerau Party, each registered on 5 August 2026. These additions do not imply confirmed candidates or election results. National’s first-home loan proposal now also cites its original party release; the earlier Scoop-hosted source is retained.

The five annual economic series were checked without a numerical change. This was a partial verification: access restrictions and unresolved historical evidence prevent a completed whole-site check. The methodology explains the difference between content updates and full-site checks.

Local data revision · 16 September 2026

Completed all 696 electorate candidate tables and party-vote breakdowns for 1996–2023, including 611 electorate candidacies and 670 party-list entries from the 1996 original scans. Candidate totals, winning margins and party votes are checked against independent official totals. Secondary evidence for individual affiliations is labelled and unresolved affiliations remain explicit.

The policy archive contains 121 summaries covering all 120 selected party/year/topic combinations. Five current Te Pāti Māori positions retain unknown first publication dates; NZ First's prostate-screening policy retains its 2025 publication date and a separate 2026 observation date. These distinctions prevent old or undated statements from appearing to be new announcements.

Added historical polling stages and participation figures, 55 Premier/Prime Minister tenure rows, reviewed MP membership tables and separate directory year summaries. Examined every tenure row in the 103-page historical parliamentary roll, with source-backed corrections and an explicit list of unresolved source errors. The roll and profile collections remain separate to avoid counting overlapping records as unique service periods. Integrated 13 party-history overviews and 45 milestones into the versioned dataset. Advance NZ's 1995 and 2020 registrations have separate identities. Northland's 1996 majority retains an explicit source discrepancy: the two highest candidate vote totals give 5,916, while the official winner summary prints 5,961. The later Port Waikato result and coalition formation remain separate events.

Added source-backed electorate tables for 2014, 2017 and 2020. Party vote shares for 2017 and 2020 now use the official statistics at two decimal places, replacing rounded homepage figures. Underlying vote counts are unchanged.
