The Dutch government has unveiled plans for almost 90 reduced-capacity pilot concerts over the course of nine days in April as part of a wider reopening programme.

Culture, sports and recreation test events will take place across the Netherlands this month, with attendees required to bring a negative COVID-19 test certificate in order to enter.

The trials will see museums, casinos and zoos across the Netherlands open for a limited number of visitors, while 425 people will be admitted to performances at the Dutch National Opera & Ballet.

In addition, 4,000 spectators will be present at the FC Groningen football match against PSV Eindhoven, and 5,000 people will be welcomed at the Keukenhof flower gardens and atArtis, a zoo in the centre of Amsterdam.

Ticketholders will be able to book an appointment for a test online and will receive their results via email within one hour of being tested.

If negative, attendees will receive a code that can be converted into a text certificate via the CoronaCheck app, which will be valid for 40 hours.

The aim of the pilots is to open sectors earlier than is possible, with the events to assess whether visitors are confident to return, as well as looking at what the experience is like for visitors to do a test beforehand to gain access.

The pilot events will also evaluate what the experience will be like for organisations checking for a valid negative test certificate at the gate. Attendees must also wear a mask when necessary and maintain 1.5-metre distance from others.
