Despite earlier concerns, the Kiwis have been "treated like kings" ahead of next Sunday's (NZT) test against England in Denver.
The debate around the mid-season test's timing saw the ruling out of several Warriors stars from the squad, with Roger Tuivasa-Sheck, Shaun Johnson, and Tohu Harris all unavailable for the match.
But Kiwis doctor Greg McLeod ensured the current team, that features seven Kiwis rookies, were following every necessary precaution in order to maintain optimal health ahead of the game.
"There was a lot of talk around this trip and the potential risks and the player welfare issues ... so the planning for this trip started well before we arrived on the weekend," McLeod said in a press conference earlier today.
"We had a look at some very specific things around immunity and making sure the guys don't pick up viruses, thinking about all those things so they arrive ready to play."
"Not just the usual compression and hydration stuff but we had a few other sneaky tricks up our sleeve to ensure that even when our guys weren't moving around, their circulation was pumping."
McLeod said that he was well aware of the concerns expressed by clubs and confirmed that their plans and strategies were communicated through a "transparent" process.
"We had an open and transparent process of how we were going to look after the players ... we didn't feel there was any smoke and mirror stuff it was all really open and we've consulted very widely," he said.
"Along this week we'll be communicating with their clubs and when we go back similarly too, everyone is going to have a plan and no one is going to be guessing."
Kiwis wing Dallin Watene-Zelezniak believed that the team had so far been given clear and helpful instruction in preparation for the test and said he felt they had been "treated like kings".
"The doctor gave us times that we needed to sleep, times we needed to eat, the water we needed to drink, and all the boxes have been ticked," Watene-Zelezniak said.
"It's actually been really cool to learn about how to prepare for games ... I feel that we've been treated like kings."
McLeod said the plan for the following days was to ensure players were back to a normal "physiological space" before commencing quality training.
"There's a couple of other tricks we have ready to keep the guys healthy and really stopping those sicknesses creeping in," McLeod said.
"I feel we've arrived ready considering how far we've come and what we've had to do ... we're pretty happy."
