While Mooar has only joined on a short term basis for the duration of the Six Nations, Scotland have opened the door for his stay to be possibly extended.
“He was involved in the three-test series against Ireland. In the first test a couple of coaches got Covid so I think he maybe led the programme that day,” Townsend added.
“He is someone who has had a lot of experience at both club and test level.”
Mooar has previous experience working in the Northern Hemisphere, having coached Welsh side Scarlets before joining the All Blacks.
The All Blacks paid a six figure sum to break Mooar’s three year contract with the Scarlets in 2020, but last year decided he wasn’t the right fit to lead their attack after the All Blacks slumped to four losses in five tests.
Glasgow Warriors assistant Pete Horne has also joined Townsend’s coaching team at Scotland.
Scotland begin their Six Nations campaign against England at Twickenham on February 5.
