The doctor for the New Zealand Olympics team says the athletes are in good shape leading up to the start of the Games this weekend.
Athletes have three days to prepare before the start of the Games on Saturday, where 184 Kiwi Olympians are competing.
Doctor Lynne Coleman told TV ONE's Close Up tonight she was happy with the physical standard of the athletes.
"Everyone has presented themselves in really good nick.
"They have done the work, they have had the results in the last 12 months, so we are optimistic."
Coleman said the athletes were professional about recovery, with the quick turn around from competing in other events to the Olympics.
Middle distance runner Adrian Blincoe has been the only athlete to pull out of the Games so far after failing to recover from an ankle injury.
Blincoe wished the rest of his team luck in the competition.
Team leader Dave Currie said he had a lot of confidence in the team, and that the athletes had worked "extremely" hard in the last four of five years to compete on the world stage.
"We are going into these Games in a far more comfortable state than we've ever gone into them before.
"I've never seen athletes quite as clear and determined as this group."
Currie said he was looking forward to the opening ceremony, where around 60 of the 184 Kiwi athletes will march, but would not reveal who would bear the New Zealand flag.
"We are going to reveal that at a function tomorrow night."
However, Currie did say the country would be "delighted and enthralled" in who had been chosen.
