Music remains his first love, however, stretching back to 1980 and his first band Fourplay, which lasted four years, and which was good enough to perform at three Sweetwaters festivals.
Various other bands followed over the years, and he was a regular performer at Ponsonby's infamous Gluepot Hotel. He also led a series of gigs at the Gluepot's corner bar featuring well known and lesser known songwriters.
When the Gluepot closed, he carried on the concept at the Java Jive, eventually starting up his own venture, Eel Music, until 2006 when he moved with his family to Eskdale.
Since August 1, he has been offering free downloads of his first solo album, East, and he is releasing a new album, Archive - a reflection of the material it contains - in parts over the next two months.
He has been working with bassist Steve Healey doing different versions of Moffat originals and, with Barry Holt, who played lead guitar on East, being back in town he's thinking once again about putting another band together.
Knowing his way around a stage has certainly helped Moffat, although Mamma Mia director Wendy Revell has been "very patient" helping him find his way through the slightly unfamiliar territory of live theatre, he reckons.
"It's been like one extended acting lesson."
