Ministry of Health - Goodbye Email Requests, Hello App
The challenge
Proof of vaccination was essential to employment and accessing services, and what began as a trickle of email requests from Kiwis seeking proof soon turned into thousands.
The Ministry of Health needed an agile digital solution that could:
- eliminate errors from manual data entry
- speed up vaccination letter processing
- respond swiftly to privacy requests.
The Ministry knew that swift responses were crucial, and they needed a scalable, secure solution.
The solution
Working as a team, the Ministry and Voco created a self-service portal using the Microsoft Power Platform, featuring:
- API integrations for data verification and automated letter generation
- a user-friendly single-page interface for efficient request processing
- automatic notifications for issue identification.
The results
The Ministry drastically improved its ability to handle proof of vaccination requests. During the portal's operation, 364,000 vaccination letters were automatically generated, a massive time saving compared to the previous 10-minute manual processing per letter.
For the Ministry, this solution:
- reduced people requirements
- mitigated 'key person risk'
- offered an audit trail
- provided valuable insights through reporting.
And for New Zealanders, the solution:
- streamlined the request process
- offered guidance on data issues
- delivered letters quickly
- prioritised time-sensitive requests.
