All Blacks winger Richard Kahui will miss next month's three-Test series against Ireland with a shoulder injury, his Super 15 team the Waikato Chiefs said Tuesday.

Kahui's absence throws a potential lifeline to Zac Guildford or Hosea Gear, both of whom were omitted from New Zealand's 35-man training squad for the series named on Monday.

The 27-year-old dislocated his shoulder in the Chiefs' loss to the Queensland Reds on Sunday and the team confirmed on their Twitter feed that he had been ruled out of the Ireland Tests.

"Richard Kahui is to miss the All Blacks June Tests, and will see a specialist this wk about best course of action for recovery," they said.

Kahui, part of New Zealand's Rugby World Cup winning squad last year, has a long history of shoulder injuries, which has restricted him to 17 Test caps since his debut in 2008.
