The IRFU has announced that Greg Feek will join the Ireland national coaching team on a full-time basis from the start of the 2014/15 season with a two-year-contract.
Feek joined Leinster as scrum coach for the 2010/11 season and has been involved as a specialist consultant with the national team for the last three years.
The new role includes the coaching of the national team scrum as well as being involved in the National Scrum Development Programme.
Through the National Scrum Development Programme, Feek will be working with the provincial and under-age scrum coaches to identify and develop scrum talent and will focus on improving players' general understanding of scrum mechanics and technique.
Feek won ten caps for New Zealand between 1999 and 2001 and played Super Rugby with the Canterbury Crusaders.
Before joining Leinster, he held the role of scrum resource coach for the Wellington Hurricanes franchise.
Ireland head coach Joe Schmidt has commented on the appointment, saying: "Greg played an important role during the Six Nations and the national coaching team are delighted that he will be joining us on a full-time basis.
"He will also be a valuable addition to the national scrum development programme.”
Feek himself said: "I am excited to be taking on this new role. I have thoroughly enjoyed my time working with Leinster and have grown as a coach at the province.
"There is some good scrum talent across all four provinces but there is always plenty to work on as we attempt to maximize the growth and development of the emerging talent while also staying as competitive as possible at the top level."
