Interviews with stakeholders in deprived Hawke’s Bay schools early in the COVID-19 lockdown documented exacerbated food insecurity among school whānau. Our enquiry highlights the support role played by well-informed teacher aides and school–whānau networks, which were easily and inexpensively resourced, intuitive, proactive and collaborative, ensuring whānau access to appropriate support according to need. We expect our findings to further inform such initiatives in any further lockdown.
