Volunteering predicts happiness among older Māori and non-Māori in the New Zealand health, work, and retirement longitudinal study.

Objectives: This study sought to understand the relationship between volunteer activity and happiness among a sample of older adult New Zealanders. It specifically sought to determine if ethnicity (Māori vs. non-Māori) and economic living standards (ELS) functioned as moderators of the relationship between volunteering and happiness.
