He's now won five South Island titles, three North Island championships and three New Zealand championships, but Friday's win ended a wait of 18 years since the last of the big triumphs in 2005.
Magee, who has been trialling dogs for just two years, got on the leaderboard for a few days at his island and national championships debut in Southland last year, and set a goal to win.
On Friday, the win with bitch Edge became the first Open title for either the man or his dog at any level, although they had a solid form line together, with 11 second placings in 16 runoffs.
Veteran Waikoau triallist Kevin O'Connor, who became a household name in winning three titles on A Dog's Show about 40 years ago, was fourth in the long head with Jax; Howard Inglis, from the Waimarama-Maraetotara club, was fourth in the short head and yard; and Ned George, of Wairoa, was second and fourth in the zig-zag hunt with Pitch and Kruger respectively.
Magee, a former pupil of St John's College, Hastings, and son of triallist Grant Magee, bought into the line of Neville Marr, a long-time triallist who placed in a New Zealand championships runoff in 1993.
With time to burn while on the Cook Strait ferry on Saturday, Magee said he'd rung Marr straight after the win. "He was almost crying," Magee said.
Soon headed to become a stockman on a property near Taihape, Magee says sheep dog trialling has become his sport, and the training up level.
"I put a lot of time and energy into it," he said. "Every morning and evening."
