The King of the Mountain win was also a welcome boost for him ahead of the Honda New Zealand Motocross Grand Prix, set for Woodville next weekend, which will be quickly followed by the four-round nationals – round one in Taranaki on February 4, then Rotorua on February 25 and Hawke's Bay on March 11m before wrapping up at Taupo on March 24.
"I didn't have any real expectations arriving here," Carter said afterwards.
"This is only my second ride back since recovering from an injury I sustained while racing in the United States in June. My first comeback ride was at the Whakatane Summercross (just after Christmas) and I finished runner-up that day, so I guess it's all looking good for the rest of the season now isn't it?
"It was really a last-minute decision to come here because the weather forecast wasn't great and this event was cut short because of heavy rain last year. But I'm so glad now that I made the trip.
"I finished fourth overall at the Woodville GP last year and third in the MX1 class at the nationals last year, so I feel it's time for me to start winning.
"With all then coaching that I'm now doing, I think it helps me to focus also on my own riding and it's certainly improved. I'm thinking about my technique all the time.
"Today was a dummy run for what I can expect in some of the bigger race situations, like Woodville and the nationals, so I was pushing quite hard today. I learned a few things about this track today and flowed quite well on it, so I'm feeling quite confident ahead of the nationals."
