Demand for Covid-19 tests in Tāmaki Makaurau remained high on Tuesday, reports The Spinoff, with at least two west Auckland testing sites running out of rapid antigen tests (RATs) before having stocks replenished. Testing centre staff will assess those seeking a test and determine whether a RAT test is suitable to be taken home and self-administered. As the tests are less reliable than the PCR tests, a follow-up swab is usually required if the RAT result is positive.
