A quick guide to understanding political polling in New Zealand, this booklet outlines how polls work, aspects of polls that speak to their quality, including sample size, error, and sampling methods, and how polls relate to actual party representation in parliament.

Public opinion polling is an important tool for understanding how a population feels about a particular issue, or which political parties they would vote for. But which details about a poll matter, and why?
This guide offers a brief overview of what information to look out for about a poll, and why this information should be transparent. It outlines how polls work, aspects of polls that speak to their quality, including sample size, error, and sampling methods, and how polls relate to actual party representation in parliament. Journalists reporting on a poll should report information on each of these features as they give important information to evaluate the reliability of the poll results.
If you’d like more information about each of these points, and political polling in the New Zealand context, please consult the accompanying detailed guide, accessible here .
There is an expressed need of Māori providers and communities for high quality, localised information that can be used to inform and monitor interventions to improve key Maori health outcome measures. Te Hao Nui is a longitudinal study that will link together the data from Te Kupenga, the Integrated Data Infrastructure (IDI), and the Longitudinal Census Database to create the world’s largest and most comprehensive indigenous longitudinal study capable of following individual pathways forwards and backward in time.

The study entirely draws on previously collected administrative data, no new data are collected as part of this project.
Focusing on informing local interventions and policy, this project will transform national statistics into locally accessible information linked into service delivery planning and evaluation at the iwi, rohe as well as at the regional level.
Linking into existing iwi and regional Māori development plans, this project will produce information that will immediately inform the delivery of services and interventions to improve rangatahi wellbeing.
It will additionally create a permanent resource within the official statistics system that can be used for research, evaluation, and monitoring of rangatahi well-being on an on‐going basis.
A tool enabling users to explore how the number and type of Māori electorates change with changes in both the Census population counts and Māori electoral roll enrolment.
The number of electorates in New Zealand is determined by a calculation based on two sources of information — the results from the most recent Census of Population and Dwellings and the proportion of individuals of Māori descent aged over 18 years who have chosen to be listed on the Māori electoral roll.
This tool enables users to explore how the number and type of electorates change with changes in both the Census population counts and the Māori electoral roll enrolment.
Consequently, this tool provides estimates of electorate numbers that are as accurate as possible, but the definitive answer is only possible with access to information that is not publicly available. However, it provides an effective tool to explore the sensitivity of the number and types of electorates to changes in population counts and electoral enrolment.

The Māori Electorate Explorer is currently being updated with more recent information.
IDI Search is a web app that allows researchers to search for variables that are available in the IDI and, in some cases, metadata about these variables. The app uses data from IDI variables and Data Dictionaries shared with us by Stats NZ. The data are stored in a database which can then be searched using the web app.

This project was initially funded by an MBIE Endeavour Fund grant, with further development carried out by iNZight Analytics. Ongoing resourcing from 2025 is provided by Stats NZ.
