Over the past decade, existing research has investigated various solutions to enhance safety management on construction sites. Among the many solutions, developing a web-based safety platform has increasingly become a key element in safety improvement strategies. International research shows that safety management platforms improve migrant workers’ safety, but evidence for such interventions in New Zealand, especially for Chinese migrant construction workers, remains limited. This study built a web prototype catering to Chinese migrant construction workers in New Zealand. The data collection method was semi-structured interviews, and the effectiveness of the novel web prototype was validated based on respondents’ feedback. Results show that this safety web prototype can effectively improve the safety knowledge and safety awareness of Chinese migrant construction workers by providing local safety policies and conducting multi-frequency long-term safety training tests. The incentive function in this web prototype can motivate Chinese migrant construction workers to use this application and enhance their safety compliance. The limitations of this research include geographical restrictions and a small sample size to evaluate the effectiveness of the prototype. Future research should incorporate a larger, cross-sectional sample to assess the effectiveness of web-based safety awareness solutions, enabling more generalizable conclusions for construction workers of diverse nationalities and regions.
