It is the first time three siblings have competed for New Zealand at an Olympics.
Rebecca Sinclair, who competed at Vancouver four years ago, is ranked No12 in halfpipe; Anna Willcox is No9 in the freeski slopestyle rankings and a good chance, having sailed slightly under the radar in the leadup to the Games.
Jossi and Byron Wells have had injuries to cope with in their preparation, to heel and knee respectively.
For Jossi Wells, getting to a first Olympics, and with his brothers and father Bruce as coach, is "pretty amazing".
"It's a pretty unreal experience," he said while batting away issues over medal expectations.
"My main goal whenever I go to a contest is to do my very best and focus on that.
"I try not to let the pressures outside in my mind. But I'm aware of the pressure and expectations back home and try to use that to do my best."
A sobering note on New Zealand's medal aspirations came from Winter Sports high-performance boss Ashley Light.
"The variability of podium results over the last 18 months have seen 25 names on the podiums in some disciplines," he said.
"So we know while New Zealand certainly have athletes with potential and capable of winning medals, there's also a whole load of other athletes around the world who are capable.
"There's massive variability and that comes down to conditions, the health of the athletes, the features being built and whether they suit the athletes."
Besides Sinclair, the other two who have competed at a Games before are skeleton racer Ben Sandford, back for his third attempt, and speed skater Shane Dobbin.
There had been hopes Dobbin would have company in the form of Blake Skjellerup, but although he may have met New Zealand Olympic Committee standards, there was no quota spot available for New Zealand, so he misses out.
Adam Barwood ensured an alpine skiing presence with some decent form at the right time coming to the business end of the qualifying period.
Overshadowing the Games, however, is the spectre of Sochi being on terrorist alert.
It is an unsettled region politically but NZOC chief executive Kereyn Smith said yesterday the organisation was satisfied with the level of security in place.
"In terms of planning and delivery of safety and security for athletes, we're comfortable the Russian authorities and the IOC are working in a comprehensive manner," she said.
"We are taking advice from government agencies and their international partners.
"Athletes' security and safety is absolutely paramount."
