The word from referee followers who follow appointments much closer than me is that, based on FIFA's track record on appointments, O'Leary is likely to get a dead rubber game on the final day of a group.
Could well be right - giving so many Fourth Official gigs to Tahitian Hauata suggests they might be keeping O'Leary for bigger things like reffing a game.
Although FIFA gave NZ officials more responsibility earlier on last World Cup when they let NZ ref Mike Hester take charge of the first game in the group for South Korea v Greece last World Cup with O'Leary and Hintz running the lines.
