Opinion polling for the 2023 New Zealand general election

Several polling firms conducted opinion polls during the term of the 53rd New Zealand Parliament (2020–2023) for the 2023 New Zealand general election. The regular polls are the quarterly polls produced by Television New Zealand (1 News) conducted by Verian (formerly known as Colmar Brunton and Kantar Public) and Discovery New Zealand (Newshub) conducted by Reid Research, along with monthly polls by Roy Morgan, and by Curia (Taxpayers' Union). The sample size, margin of error and confidence interval of each poll varies by organisation and date.

The current parliament was elected on 17 October 2020. The general election took place on 14 October 2023.

Nationwide polling
Poll results are listed in the table below in reverse chronological order. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. The 'party lead' column shows the percentage-point difference between the two parties with the highest figures. In the instance of a tie, both figures are shaded and displayed in bold. Percentages may not add to 100 percent due to polls not reporting figures for all minor parties and due to rounding. Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between survey organisations.

The parties shown in the table are Labour (LAB), National (NAT), Green (GRN), ACT, Māori (TPM), New Zealand First (NZF), Opportunities (TOP), New Conservative (NCP), and New Zealand Loyal (NZL). Other parties may have also registered in some polls, but are not listed in this table.

Tauranga
An opinion poll was held in the electorate prior to the June 2022 Tauranga by-election. The by-election was won by National's Sam Uffindell.

Preferred prime minister
Some opinion pollsters ask voters who they would prefer as prime minister. The phrasing of questions and the treatment of refusals, as well as "don't know" answers, differ from poll to poll. To qualify for this table and graph, this person must reach at least 3 percent in three separate polls.

Government approval rating
The government approval rating is a statistic which measures the proportion of people who say they think the country is heading in the right direction or wrong direction politically.
