A guide for critical workers for getting a Rapid Antigen Test (RAT) under the Close Contact Exemption Scheme, how to self test and how to register the result.

Rapid antigen tests (RATs) are a type of test which can be carried out at home or with minimal support required. A swab is taken from the front of the nose and results are usually available within 20 minutes.

This guidance is for critical workers in our Omicron response. It covers the models for accessing RATs under the Close Contact Exemption Scheme (CCES) depending on the worker's employer, how to self test and how to register the result.

Please note - From 11:59pm Friday 11 March, the isolation requirements for cases and their household contacts has been reduced from 10 days to 7 days. Household Contacts will need to test on Day 3 and Day 7. We are working to update this guide. For the most up-to-date isolation requirements, please go to the Contact Tracing page on the Ministry of Health website:
