A veteran of six years in the class, Baker said he enjoys racing at Meeanee.
"It's different to Western Springs which is wide open. Here it is a bit more technical. At the Springs you can drive the top of the track all race ... but it's nice to get away from the Springs."
With two seconds and a fourth placing Baker beat his brother by four points for the title.
Baker said he hopes Saturday night's success will prove to be a good omen for the Nelson-hosted nationals on February 9 and 10.
"I've got the Barry Butterworth feature at Western Springs next weekend. But because I won that last year I have to start off the back this time so it will be tough.
"I'm leading the Western Springs Series from Scott and I'm hoping to hang on to that lead in our final round on February 17. Because of that meeting I will miss the New Zealand Grand Prix meeting in Greymouth."
A bicycle salesman, Baker is hoping to move up to the midgets class when he leaves TQs.
