New Zealand qualified for London with a largely domestic-based squad of amateurs but Emblen has been able to call up a number of players - including three overage players - with professional and senior international experience.
That proved a double edged sword recently with the team playing catch up with a build up en route to the UK with games against Korea, Japan and UAE in Asia and Austria.
But Emblen says the settle nature of their preparation since arriving in Coventry has helped get the side up to speed.
"It's been nice to get on the training pitch over the past four days and get to work.
"We went into those warm up games with no time together, needing to give players match time and find out what we needed to work on.
"We've had some time now to settle and work on the things we learned from those games, and everyone now knows their roles much better.
Goalkeeper Jake Gleeson has been back in training for the past couple of days and is available for selection while other players nursing niggling are not expected to be affected enough to prevent them playing a part if called up to the team led out by Ryan Nelsen.
