No. French Polynesia doesn't ask visitors to fill in an online arrival form (also called an entry form, immigration card or landing card) before they travel. The COVID-era ETIS online registration has not been required since 28 March 2022.
Do I still need a visa for French Polynesia?
An arrival form is not a visa. Whether you need a visa or an electronic travel authorization depends on your nationality, so check French Polynesia's official immigration website or your own government's travel advice.
