"We have identified a gap between our top juniors and elite level. To make the jump from a teenage junior, no matter who you are, or what you have done, into the elite squad is quite difficult. Our elite squad is now very strong and that jump is even more difficult.
"The space I am working in is providing opportunities for this group to come together and train, experience things like the World Cup and Oceania Championships, so that we do not lose them.
"Without the help then they might just wander away rather than have the patience to keep working at it.
"We only had a very small number of elite riders when I was racing but it is a different game with the depth that New Zealand has these days and having the development programme in place is only going to be good for our future."
This week's targets are small — to secure a second ride — which means they will need to be in the top eight in qualifying.
"We are already going well and have high hopes. We are after small targets here but the key one is to get a second ride in the team pursuit and to do that we have to qualify in the top eight. That will mean breaking four minutes which none of them have done before.
"When we [New Zealand] broke four minutes, I think it was 3:59, we felt we were kings. Now they are breaking 3:50. I think we are going to see some really fast times in Cambridge this week."
Roulston is loving his new life as a coach. "The thing I bring is that I have done it before. I know the pressures and the stress, I have had the limelight. I am enjoying the challenge of bringing young riders together and performing on the day."
