Social trust is vital for immigrant societies with diverse backgrounds, as it bridges differences, fosters mutual understanding, and facilitates collective actions. While most studies on the relationship between religion and social trust focus on North America and Europe, little is known about this dynamic in New Zealand. This paper examines Chinese New Zealander Christians to explore how religion fosters social trust. The findings were derived from an interpretive analysis of 47 Chinese New Zealander Christians from mainland China, Taiwan, and Hong Kong. Most interviewees exhibited low general trust in strangers because of the complex and untrustworthy post-pandemic social environment. Believing in Christianity did not mitigate this negative impact. Interviewees’ particular trust in fellow congregators varied. Social network theory offers a plausible explanation for this phenomenon. Most interviewees cultivated trust in fellow congregators through frequent informal interactions outside churches. Regular face-to-face religious activities and a shared religious identity had little impact on forming particular trust in other Christians. Furthermore, Chinese Christians were internally divided based on their homelands and dialects, hindering them from constructing a shared identity. The findings enhance our understanding of how religion affects social trust among ethnic minority immigrants and their identity construction within religious communities.
