Apparently from 3 March on there will be adjustments to the travel test policy. At this moment it seems to be published only in dutch on the NL goverment site.
Nederlands -> English google translation comes up with:

Adjustments to Travel Test Policy
NAAT tests

More corona tests will be allowed from 3 March. Now there is the PCR test. This is a so-called NAAT test. In addition to the PCR test, there are more NAAT tests. All NAAT tests are allowed from 3 March. So also the tests under the names mPOCT, NAAT, or RT PCR, LAMP and TMA. The PCR test obligation then becomes the NAAT test obligation.

Negative COVID-19 test results and declaration required upon departure to the Netherlands
At the moment, as a traveler from a high-risk area due to corona, you must show 2 negative test results when traveling to the Netherlands. From 3 March this may also be one negative NAAT test of a maximum of 12 hours old when boarding.

How far in advance should I take a test?
At the moment, when boarding the vehicle, you must be in possession of a negative rapid test of no more than 4 hours old and a negative NAAT (PCR) test that is no more than 72 hours old upon arrival in the Netherlands.
As of 3 March, a rapid test will no longer be necessary if you have a negative NAAT test of no more than 12 hours old with you when boarding.

A number of exceptions will be made as of 3 March for long-term positive travelers
Some people continue to test positive after going through corona. Even if all symptoms have already disappeared and someone is no longer contagious. The following applies to these people from 3 March.

If you have had corona and are therefore unable to provide a negative NAAT test result, you may still travel if you can show the following documents:
Positive NAAT test result from a minimum of 2 to a maximum of 8 weeks old;
Positive NAAT test result of max. 72 hours old upon arrival in the Netherlands;
Negative rapid test result before departure.
In case of a permanently positive result on the rapid test, you may travel to the Netherlands if you can show the following:
Positive NAAT test result from a minimum of 2 to a maximum of 8 weeks old;
Positive NAAT test result test result of max. 72 hours old upon arrival in the Netherlands;
