WELLINGTON will take on big clubs from England, Spain and Asia when it plays in the Hong Kong Soccer Sevens from May 29-31.
The Phoenix will be the first New Zealand club to take part in the annual seven-a-side tournament, which is in its 16th year.
Spanish club Atletico Madrid, English Premier League team Stoke City and Shanghai's SIPG will also make their debuts.
The 16-team tournament regularly features the world's biggest clubs with Manchester City taking the title in 2014.
This year's line-up will include fellow EPL teams Aston Villa, Leicester City, Newcastle United, and West Ham United.
"It is a brilliant opportunity to compete against the world's best," Phoenix chief executive David Dome said.
The Phoenix will take a squad of 10 players - from the A-League roster and Academy program - and travel to Hong Kong on May 27.
