The government of French Polynesia has just announced that they will accept a specific type of Antigen Test as an alternative to the RT-PCR test for entry into Tahiti. The RT-PCR test has been in place since July 2020. As mentioned in our French Polynesia COVID-19 Entry Protocols, the Antigen test must detect the "N" protein of the SARS-CoV-2 virus.
This test should prove to be more widely available, be less expensive, and produce faster results.
