He made his début for the Kiwis in the 1988 World Cup final against Australia. Playing on the wing, he scored a try on debut, but the Kiwis were defeated 25–12 in front of 47,363 at Auckland's Eden Park.
In 1990-91 he returned to England for a short stint with Leigh.
He played at the 1995 Rugby League World Cup for the Kiwis, helping them to the semi-finals where they again went down to Australia in extra time.
He signed with new Super League club Hunter Mariners and after a season with his brother Kevin, ventured to play for the Adelaide Rams after moving to the forwards. Iro, who at the time played for the short-lived Adelaide Rams (1997–98), earlier in 1998 became the only Rams player selected for international duty when he played in the ANZAC Test against Australia at the North Harbour Stadium in Auckland. Iro's last international series was against Great Britain in England in late 1998 where he played from the bench in the first two tests of the series, both won by NZ. Following the demise of the Rams, 1999 found Iro at the South Sydney Rabbitohs before his return to England.
