Electorate candidate
Everything a candidate spends on advertising in the three months before polling day.
✶ New Zealand · 2026 general election
A New Zealand party can spend at most about $4.06m on its whole campaign. It cannot buy television or radio advertising with its own money: broadcast ads come out of a public allocation the Electoral Commission shares between parties. There are no PACs, and every donation over $6,000 a year must be published.
Public money · decided 8 May 2026, varied 7 August 2026
Parliament set aside $4.15m (including GST) for party election advertising on radio, television and the internet. The Commission weighs each party's vote and seats at the last election, its MPs, polls, membership and "the need to give a fair opportunity" to each party. In all $4.15m went to 15 parties.
Parties may not spend their own money on radio or TV advertising time — only this allocation (Broadcasting Act 1989 Part 6, as described in the Commission's allocation decisions; the current text of the Act was not read for this edition). They can spend their own money on online, print and outdoor advertising, within the overall limit.

Compared with the United States
US campaigns have no spending limits; New Zealand parties, candidates and third parties all do.
US candidates buy unlimited airtime; NZ parties use only their allocation for radio and TV.
Outside groups register as promoters and are capped at $424k.
