Important characteristics when defining New Zealand as rated by men

Social identity: an individual’s identification with, or sense of belonging to, a social group. An important form of social identity is national identity.
Sense of belonging: a feeling of being an accepted member of a group. People can experience a sense of belonging to different groups and at different levels; e.g. to family, friends, co-workers, a sports team, an ethnic group, or a country as a whole. Feeling a sense of belonging to a group or groups helps people identity who they are as an individual.
Characteristics of New Zealand's national identity: the 'common points' in people's lives that form New Zealand's national identity. The characteristics that become part of a country's identity are strongly shaped by what distinguishes it from other countries. Despite a national identity being collectively shared, the perceived characteristics of this identity and how they are prioritised may differ.

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 New Zealand General Social Survey (NZGSS) produces statistics about social well-being to inform decision-making by government agencies and the wider community. Data gathered includes objective information about circumstance, such as labour force status and income, as well as a personal assessment of different aspects of New Zealander's lives, such as life satisfaction, health, housing, human rights, and relationships. In particular, the survey provides a view of how well-being outcomes vary across different groups within the population.

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). We randomly select one individual in the household aged 15 years or over to answer the personal questionnaire.
The survey period for the survey is therefore April to November 2016, then January to April 2017. The sample size was approximately 12,000 households.
