ESR Privacy Statement for COVID-19 Testing and Reporting

The Institute of Environmental Science and Research Limited (“ESR” or “we”) has multiple roles in the pandemic response. Two of these roles involve ESR:

  • operating a national clinical data repository, called Éclair, on behalf of the Ministry of Health, to collect and maintain all positive and negative COVID-19 test results. Information collected and processed includes personal information relating to individuals. This information is used to support the Ministry of Health, District Health Boards and Public Health Units in monitoring and managing the prevalence of COVID-19; and
  • using Éclair to provide an electronic ordering solution of COVID-19 tests, including the automated distribution of test orders and results designed to assist laboratories to quickly process test results.

This privacy statement sets out how your personal and health information is collected, used, disclosed and protected by ESR (acting as agent on behalf of the Ministry of Health) when you undergo a COVID-19 test, as well as how you can access and correct any personal information we hold about you.

ESR works with a number of laboratories around the country who undertake the physical testing for COVID-19. ESR plays a key co-ordination role in how the testing is undertaken and the information is recorded as part of the testing.

You should also consult the laboratory that completed your test for their specific Privacy Statement which will set out how they manage and distribute the data they hold.

Collecting your information

The following personal and health information about you will be provided by you directly to either your GP, a hospital staff member, a managed isolation quarantine facility staff member or a community testing staff member when you request a test.

  • Your full name, NHI number, recent travel, contact history, surveillance code, symptoms, clinician responsible for order, assessment date, mobile phone number, date mobile number was validated, whether to notify patient of negative result, occupation, employer and workplace address.

  • If you have a test at a MIQ facility, your date of isolation, room number, whether you are displaying COVID-19 symptoms and whether you are confined to your room will be recorded.
  • The laboratory processing your test will collect your NHI number, email address, mobile phone number, test status and test result.

Your patient National Health Index (“NHI”) number and associated data including your full name, current address, email address, phone numbers, date of birth, place of birth, mother’s birth name, residency and citizenship details, ethnicity, language, gender, and usual GP clinic has been securely provided to us by the Ministry of Health and will be linked to the personal information you have provided in our Éclair database.
