Data with high sampling errors should be used with caution. Estimates with high relative sampling errors (RSEs) between 50 and 100 percent are considered unreliable for most uses.
The data collection began on 1 April 2021, a year after the first COVID-19 lockdown, and finished early, on 17 August 2021, due to the first community outbreak of the Delta variant. The survey was unable to go back into the field.
The reduced collection period for GSS 2021 resulted in a smaller sample size compared with previous GSS collections, and the sampling errors on the estimates produced were larger. The response rate for the sample from April through to the end of August was 75.9 percent.

Wellbeing statistics: 2021 (supplementary) presents supplementary data from the 2021 General Social Survey (GSS), adding to the data released in Wellbeing statistics: 2021 in July 2022.

This data is presented in four topics: social networks, family, and sense of belonging; civic and cultural participation; volunteering; and satisfaction with the natural environment.

Stats NZ use household and personal questionnaires to collect the data. One individual in the household completes the household questionnaire, which collects information about all the usually resident people in that household (eg family relationships and household income). Stats NZ randomly select one individual in the household aged 15 years or over to answer the personal questionnaire.
GSS 2021 has a reduced sample size of 3,484 person responses, this compares with approximately 8,000-8,500 for a normal 12-month collection.
