The VHIN is a network of researchers, analysts and other professionals who use health data to generate insights that support the health and wellness of all New Zealanders. The network facilitates sharing and collaboration amongst network members in order to enhance health research outputs and improve health service delivery and health outcomes in New Zealand (About VHIN).

A deeper understanding of the IDI and increased awareness of data quality issues can be gained via online guides, discussions on the VHIN Facebook page, analytical code from VHIN research projects and our shared code repository, explanatory material from meetings and presentations about current IDI research, and courses.
