Are you travelling to the Netherlands from a country outside the European Union or Schengen Area? From 22 December 2021, you are obliged to have a negative test result with you. This also applies to travellers who already have a vaccination or recovery certificate. Always get tested before flying to the Netherlands from outside the EU/Schengen. Your negative test result may be from either a NAAT(PCR) test that was taken no more than 48 hours before departure or a from rapid antigen test that was taken no more than 24 hours before departure.

Travellers from very high-risk areas are subject to a quarantine obligation, regardless of whether you have a vaccination or recovery certificate. You can read more about this at Rijksoverheid.nl.
