Carrington (32), has taken on the role to help the Highlanders improve their goal-kicking and general kicking.
The former fullback-winger said making a good kick had not changed - it was all about technique and mental application.
"There are different types of kicks for different positions on the field. But the job now is not about going to practice and kicking 100 balls in a row," he said.
There were a lot of different styles of kicking employed, but he was keen to bring spiral kicking back into the game.
"That was the style I was taught when I was growing up but drop punting seems to be more popular now.
But spiral punting has the advantage of the ball going a lot further and the ball does not get as high so players can't get under it as easy."
Carrington, who started his career with Auckland, before shifting south, said assistant coach Peter Russell had employed a kicking coach with Hawkes Bay and wanted to have a similar person employed with the Highlanders.
Carrington had worked with Mark Tainton, who is now the Irish kicking coach, when he played at Bristol, and said he had learnt a lot from him.
Carrington played 19 games for the Highlanders from 1997 to 1999 but then went overseas for five seasons, playing in both Italy and England, before returning to Dunedin, to study physiotherapy.
"In England we seemed to practise kicking more than we practised passing."
He had graduated from the University of Otago last year and had started a job with Back-in-Motion Physiotherapy.
He was working with players for a couple of hours a week, and said it was an enjoyable job.
Carrington said goal kicking was obviously very important.
"These guys are coming into the season so it is too late to start looking at changing their technique. That can happen in the off-season. But with goal-kicking a lot of it is mental rather than the physical.
"Obviously, goal-kicking is huge. In a game like this you've got to collect the points on offer."
Under the new experimental law variations, kicking was becoming even more important, with more kicking into space, and for ground, making the game very different than when he played.
His coaching career would continue in the club season, as he was helping out the University A side with John Leslie and Shayne Flanagan.
