Wales are due to play two matches in the Pacific Islands, against Tonga and Samoa in June.
"There are still some things to iron out with Tonga, mainly that there isn't a pitch at the moment," he said.
"The stadium infrastructure is not in place so we are meeting with World Rugby again," Phillips added.
The game against the Samoans is scheduled for 24 June in the country's capital city Apia with relatively few qualms about that fixture.
