The Trust Deficit in Public Health Messaging

In early 2020, the government's COVID-19 communications were widely praised. Clear messaging, consistent updates, and a visible leader in the Director-General of Health. For general audiences, it worked. The "team of five million" narrative was effective.

But within weeks, Māori and Pacific health leaders were raising concerns. The messaging didn't reflect their communities' realities. Multi-generational households. Essential workers who couldn't stay home. Limited access to digital health services. Pre-existing conditions driven by decades of health inequity. The "stay home, save lives" message assumed a version of home that many whānau didn't have.

The vaccination rollout made the gap starker. The national campaign was well-resourced and professionally produced. For Māori and Pacific communities, it wasn't the message that was the problem - it was the messenger. Decades of experience with health institutions that collected data, delivered services paternalistically, and failed to address systemic inequity meant the government's voice carried limited authority.

While government agencies struggled to reach Māori and Pacific communities, something else was happening. Iwi health providers, Pacific churches, community organisations, and marae were running their own vaccination drives. Te Rōpū Whakakaupapa Urutā, the National Māori Pandemic Group, mobilised within days. Pasifika Futures coordinated Pacific community responses. Iwi across the country stood up testing stations, delivered kai to isolating whānau, and communicated through their own networks.

These organisations didn't have the government's budget. They had something more valuable: existing relationships and earned trust.

At Te Hiku, I watched the iwi communications team achieve engagement rates that the national campaign couldn't match. Not because the creative was better. Because the messenger was trusted. The information came from people the community knew, in language that felt natural, through channels that were already part of daily life.

The trust deficit didn't appear overnight. It was built through decades of specific institutional behaviours.

Data extraction. Māori and Pacific health data has been collected for generations - used for research, policy development, and funding cases, rarely with tangible benefit flowing back to the communities that data came from. Communities learned that sharing information with health institutions meant losing control of their own narrative.

Paternalistic service delivery. Health services designed around mainstream assumptions about how people seek care, manage illness, and make health decisions. Services that implicitly positioned Māori and Pacific health practices as insufficient and Western clinical models as the standard.

Unfulfilled commitments. Successive governments promising to address health inequity, commissioning reports, launching strategies, and delivering marginal improvement. Each unfulfilled commitment reduced institutional credibility.

The public health communications lesson from COVID is not about better campaigns. It's about who holds the authority to communicate on health.

Government institutions can fund, coordinate, and provide clinical evidence. But in communities where institutional trust is low, the government cannot be the primary messenger. The primary messenger needs to be someone the community already trusts.

This requires a different model of public health communications - one where government agencies resource community communicators rather than producing national campaigns and adapting them. Where the authority to shape health messaging sits with the people closest to the community, not the people furthest from it.

COVID is not over, and neither is the trust work. The question for public health institutions is whether they'll treat the pandemic's lessons as an exception or a signal. The trust deficit wasn't created by COVID. It won't be resolved by post-COVID reviews. It requires sustained, structural change in how public health institutions relate to the communities they serve.

That means funding community-led health communications as standard practice, not emergency response. It means embedding Māori and Pacific voices in health communications governance, not consultation panels. And it means accepting that institutional trust, once lost, takes years to rebuild - and that the rebuilding starts with actions, not messaging.

The next public health crisis will come. The question is whether institutions will have done the trust work before it arrives, or whether we'll be having this same conversation again.
