"It was a pretty good journey as we had a break on the way over and had a few days relaxing on an island off Singapore," said Lualala.
"I got bored by the end because I don't like just sitting around and couldn't wait to get over. It was good to see the facilities on the internet but when you see them for real, they're very impressive.
"The training centre and stadium are brand new. We've got good facilities back home but to see things over here is quite an eye opener."
Casey made his debut for New Zealand against Wales in Cardiff in November 2004 and went on to play for the All Blacks against Ireland in 2006.
Described by many as one of the hardest players to contain in broken field play in the New Zealand game, Casey is the son of an airline pilot for Polynesian Airlines, and was schooled at Wesley College - the same south Auckland institution that gifted the world game former Cardiff Blue and international rugby superstar, Jonah Lomu.
Speaking of leaving New Zealand, Casey said, "It was good to leave Canterbury on a high having won the Air New Zealand Cup but I was ready for a change.
"I wanted a change of lifestyle and living in Europe certainly appealed. However I also wanted a change of environment on the rugby front having played for the same team for 7 years, so I was looking for something different.
"Playing in the Heineken Cup would be incredible. I watched the big Heineken Cup games on TV last season and they were awesome, but unfortunately the semi-final was decided on a kicking contest, which was a bit pathetic.
"It was impressive to see the amount of people that attended the matches as we don't have crowds that big in New Zealand.
"I think people are more passionate here - even in the Air New Zealand Cup Final we only had a crowd of 10,000.
"There were a few teams including Munster who approached me, but having spoken to Dai Young and Bob Norster I was impressed with the way they went about the whole process and the way things were conducted.
"The Blues also showed a lot of faith in me and followed me with interest when I injured my arm which was good to know as sometimes people get a bit down when they pick up injuries.
"The arm is fine now, I've played a lot of games since and it's as strong as ever. I used to play golf with Ben Blair back in Canterbury so we are big friends and he helped me make the decision.
"It will be good to see Ben again but I'm sure he will tell me all his kicking stats as soon as I see him.
"I'm sure we will go out for a game of golf to catch up, although he's the most frustrating guy to play golf against as he takes all day to get his swing and putting right."
