The 54-year-old will be stabling his team on the course and said it has already been a "real pleasure" to work Lady Maria on "such a nice, spacious track".
"The people here have been really gracious and welcoming and it's a great atmosphere for the horses," he said.
Wearing his other hats, he has already managed to pick up work in Wairarapa as a farrier and is on the market as a horse breaker.
Prior to making the shift to Opaki he worked in the Waikato for 13 years and, before that, shoed horses in Northland for the high profile Donna and the late Dean Logan partnership.
As a trotting driver he has 80 wins to his credit, achieved in New Zealand and Australia.
Track manager Peter Jeffcoat said the galloping trainers have their sights set on Opaki being the country's most successful winter training venue this season.
Last season they produced 28 winners, among them some big scalps, to record the best performance since the 2008/2009 season, when star gallopers Tavistock and Fritzy Boy ruled the roost.
Jeffcoat credits much of the track's success as a training venue to the Masterton club having " a damned good committee" along with a team of dedicated and talented trainers, but his praises have likewise been sung locally and nationally for his work with the track.
The course proper is never closed, as opposed to many other tracks in the country, where work is restricted to certain days and horse numbers limited, so if trainers want to work horses at any time, they can.
That means Jeffcoat has to be diligent as multiple horses using the course means "lots of holes and I have to fill them".
Progress at Opaki has come in the form of new tie-up stalls, the acquisition of scales to weigh horses, thanks to prominent owner Tommy Heptinstall, and now having two sets of starting gates.
On the cards are new running rails and an irrigation system.
