He hopes hard work and ingenuity combine to win him another gold medal.
Four years ago at the Vancouver Paralympics, the then 22-year-old survived a mid-race fall in his second run to dramatically strike gold in the standing slalom event.
At that time, the man who was raised on the family's dairy farm in Outram lauded his success as a victory based chiefly on perspiration.
This time around, he hopes a large dollop of ingenuity will prove decisive.
''After Vancouver, we looked at my body and discussed what we needed to do to be able to continue for another four years.
The training hasn't changed too much, just the way we have gone about it. We still work hard but we are a lot smarter in our thinking,'' he said.
Hall has adapted some sports science techniques and has worked tiredlessly in his quest for gold. Video analysis, strength and conditioning, nutrition, biomechanics have all been used in an effort to trim those extra hundredths of a second so critical on the mountain.
It is the appliance of science with a large New Zealand imprint.
The great thing about adaptive sport was everyone was completely different, he said.
Hall was born with spina bifida.
''Everyone has their own equipment to suit their own ability. That's what adaptive sport is all about. It is about being adaptive to your own needs. We decided after Vancouver to go back to the drawing board, look at my body and decide what I specifically needed to go faster.''
After extensive work, he has new equipment in his bindings and new state-of-the-art outriggers.
His training regime has also undergone an overhaul.
Hall is not sick of snow yet but the current cold months in the northern hemisphere bring it up to a total of 20 consecutive winters.
Training under United States coach Scott Olson, the emphasis was now on quality of training rather than quanity.
''I now put in some really good blocks of training and then I will back off, rather than grinding away all the time.
''When I look back at Vancouver, I was probably grinding away all of the time, whereas as I've now become more focused on tactics and techniques. This has helped me perform to a higher level.''
He has lost 10kg to get his body more tuned for racing and now races at an ideal weight of 75kg.
Hall believes he enters Sochi in good heart.
Beside his slalom specialty event, he is also lining up in the super combined and the super-G.
Hall said competition had increased greatly and it would be far tougher to win medals than four years ago.
''We have an opportunity every four years and get a chance to put in our best performance and represent our country. Right now, I'm focusing on the process of that then the results will follow. If I do I'll be rewarded with a podium spot.''
