Harington, who competes in the halfpipe discipline, starts his season this week in New Zealand.
Last year he recorded his first World Cup top 20 at the same event and a repeat of that performance would put him one step closer to Team GB selection.
However, Harington endured some mixed results elsewhere last season, breaking his wrist during training in Canada and then breaking two snowboards during the test event at next year's Olympic venue.
"It was awesome to go to Sochi earlier this year, even if my result was really bad," he said. "This week is a big event for me.
"I've got four events this season, I've got the two top 20 results that I need but I also need to get inside the world's top 40 to earn my slot and I'm currently 41st.
"I'm looking forward to getting started; it's a massive year because everyone wants to be involved in the Olympics. The standard will be incredibly high and the competition really tough."
Ben Kilner, who made his Olympic debut in Vancouver, is Britain's top ranked halfpipe snowboarder, finishing 16th at last year's World Championships in Stoneham.
He also posted three consecutive World Cup top 20s last season, including a tenth place in Park City, and will be looking to solidify his world ranking in New Zealand.
