Kiwi pair Michael Venus and Marcus Daniell are into the quarterfinals of the Olympic doubles tennis tournament after a round of 16 walkover.
Dutchman Jean-Julien Roger tested positive for COVID-19 on Monday forcing the Netherlands out of the competition and handing a free ride for the Kiwis into the final eight.
Rojer is the first tennis player and the sixth member of the Dutch Olympic delegation to test positive so far.
The others include a skateboarder, a taekwondo player, a rower and two staff of the rowing team.
Rojer and his partner Wesley Koolhof, who were scheduled to play the Kiwis on Monday afternoon, have been placed in isolation, the ITF said.
The New Zealand Olympic team has confirmed that neither Venus or Daniell have trained, travelled or come into contact with any member of the Dutch delegation.
Venus and Daniell will play for a spot in the final four on Tuesday against either Austria or Colombia.
