Census - Unpaid activities by sex by region 2018

Stats NZ

Subject matter

These figures cover activities performed without payment in the four weeks before 6 March 2018. People may do multiple activities, so the percentages add up to more than 100%. This information applies the census usually resident population aged 15 years and over, regardless of the employment status.

Response rates and final data sources

Unpaid activities: The response rate from 2018 Census forms was 82.8%. There was no information for 17.2% of people. No alternative data source or imputation was available to replace missing responses. Sex: The response rate from 2018 Census forms was 84.6%. In addition, 4.3% came from partial forms (i.e. where the sex of an individual was provided on the household set-up form or the paper dwelling form, but Stats NZ did not receive an individual form). 10.9% were sourced from administrative data, while the remaining 0.1% of data points were imputed. Region: The response rate from 2018 Census forms was 88.8%. The remaining 11.2% of responses were sourced from administrative records. Admin enumerated records were added to the census file to count people who were missed. Data from the range of sources available in the IDI was used.


Census usually resident population count of New Zealand: a count of all people who usually live in and were present in New Zealand on census night. It excludes overseas visitors and New Zealand residents who are temporarily overseas.

Changes to data collection/processing

The 2018 Census was a modernised census based on models used in 2016 by the Canadian and Australian statistical agencies and then applied in the New Zealand context. Stats NZ collaborated with census experts from both countries when designing the model.

Under the new model, how Stats NZ enabled/collected from the respondents changed from predominately field-based activities to 80 percent mail-out with a reduced field presence and increased communications, marketing and engagement. The way respondents completed their forms also changed, with a greater focus on online completion over paper. The majority of the population was encouraged to complete the census online using an internet access code mailed to their households before census night. The new collection model therefore relied on the public to self-respond, rather than wait for a visit from field staff. Field follow-up activities were also planned.

The main areas of change were:
- phasing the model (prepare, enable, remind and visit)
- strategies used across the different phases
- mailing out “call to action” letters with an internet access code and instructions on how to order paper forms, if required, as the first interaction with census
- reducing the number of field staff, with a new structure and roles
- outsourcing the recruitment functions for field staff
- introducing new field technology
- creating a new address frame (a list of all dwellings in New Zealand)
- an integrated communications campaign including community engagement
- a new approach to processing the census data.

About this dataset

The New Zealand Census of Population and Dwellings is the official count of how many people and dwellings there are in New Zealand. It provides a snapshot of our society at a point in time and helps to tell the story of its social and economic change. The 2018 Census, held on Tuesday 6 March, was the 34th New Zealand Census of Population and Dwellings. The first official census was run in 1851, and since 1877 there has been a census every five years, with only four exceptions.

Purpose of collection

Census information is used by government agencies, local authorities, businesses, community organisations, and the public for developing and implementing new policies, research, planning, and decision-making. It helps us make decisions about how to best use public funding, especially in areas of health, education, housing, and transport.
The census is also the primary source of information used for deciding the number of general and Māori electorates, along with data from the corresponding Māori Electoral Option.
