Ireland duo touch down
Gordon D'Arcy and Cian Healy joined their Ireland team-mates in Queenstown on Monday following their delayed departures from Dublin.
D'Arcy failed to travel after pulling up in training with a calf strain last Tuesday, the day the squad set off for New Zealand.
The Leinster centre could be fit to face the United States on Sunday but Healy is a doubt for the World Cup opener because of his eye injury.
Healy sustained the damage in last month's 20-9 defeat by England and was advised to allow it to heal before embarking on the long-haul flight to New Zealand.
"I was getting mentally prepared for doing the journey by myself, but I got the news that Gordon pulled up with an injury," said Healy.
"There was a sense of relief for both of us that we would still be travelling.
"Talking to some of the squad, they have settled in really well and combined training with some time to relax and get involved in the whole spirit of the tournament.
"It's good to get that down time before we pick the pace up this week.
"The intensity will start to rise now another couple of notches as we look forward to the USA game."
Full-back Rob Kearney and flanker Sean O'Brien trained on Monday and showed no ill-effects from their respective groin and knee injuries.
