''It will never be forgotten, especially as it came so soon after the Games,'' he told the Otago Daily Times from Sochi last night.
''It was such a tragic thing to happen after such a successful Games for me. Mum was known as the biggest fan I had.''
Hall has never forgotten the influence his mother had on his life and how she encouraged him with his skiing.
He also paid a compliment to the many people in New Zealand who supported him after his mother's death and have been backing him over the past four years.
Hall wants to repay that debt by winning another gold medal to make New Zealand proud.
''At the end of the day that is what we are here for,'' he said.
''That is what we are representing our country for.
''We have a good team and all the skiers are determined to give their absolute best.
''We just don't turn up to the Games and win medals. We have worked really hard over the last four years. It's all about the journey and the hard work, the sweat, blood and tears.
''We know that all the hard work will pay off with medals. We have confidence in the preparation we have done.''
Hall is joined in the New Zealand team by Paralympics newcomers Carl Murphy, one of the leading para snowboard cross standing riders in the world, and sit-skier Corey Peters, who will compete in four events.
Expectations are high the well-prepared trio can secure two medals and go one better than Vancouver when Hall won gold in the slalom despite taking a mid-race tumble on his second run.
The Wanaka-based Hall will be the first New Zealander in action at Sochi when he competes in the men's super-G tomorrow.
Among Hall's main rivals will be 2013 world slalom and giant slalom champion Vincent Gauthier-Manuel (France), Russia's 2013 world silver medallist in giant slalom and super combined Alexey Bugaev, and Austrian Matthias Lanzinger, a former able-bodied World Cup podium finisher who switched to para-sport after a leg amputation.
''It will not be easy because the sport is always progressing from season to season,'' Hall said.
''The sport has grown and it is exciting to see that happening.
''All the races are going to be tight. It is not going to be like Vancouver when I had such a big lead after that first run.
''Many of the competitions are being decided by hundredths of second - that's what keeps it exciting.
''Right now, I'm focusing on the process. If I do that, the results will follow and I`ll be rewarded with a podium spot.''
This is Hall's third Paralympics. He felt the experience he gained in 2006 helped him to get the gold medal at Vancouver four years later.
''That was a critical Games for me to gain that experience,'' Hall said.
He still feels nerves before he starts his ski run in a major competition.
''It's not a scared nerves. It is positive nerves,'' Hall said.
''It gives me confidence when I stand at the top of my run because I know I have done all the hard work.
''I have the self-belief and confidence that I will put down my best run and ultimately get the gold medal.
''A ski run is something I have done day in and day out over the last four years. It is just another day at the office for me.''
Hall recalled what it was like at Vancouver four years ago.
''It was a really great Games for me,'' he said.
''It's an opportunity every four years to show-case the Paralympics to the rest of the world.
''I feel privileged and honoured to be able to represent New Zealand, a country that always punches well above its weight.
''I felt very confident at Vancouver and I feel the same way here at Sochi and am just waiting for the Games to get under way.''
Will he be back in another four years?
''I was solely focused on Vancouver four years ago and my focus is on the task at hand at Sochi for the next two weeks,'' he said.
''I want to do New Zealand proud and be on top of the podium.''
He will not plan his future until after his debriefing from this month's Paralympics.
