The accomplishment makes Treble Cone - where Aspiring Avalanche Dogs is based - the first skifield in the country to have four fully-operational avalanche dogs on site.
''It's kind of a bit of a milestone for us and them also,'' Aspiring Avalanche Dogs co-ordinator Matt Gunn said.
''Our dogs just all totally aced it, so it was a pretty standout effort really.''
The dogs and their handlers were among 12 South Island teams put through their paces at the three-day NZ LandSAR Search Dogs avalanche assessment camp at Snow Farm this month.
Teams from The Remarkables and Cardrona Alpine Resort also passed the assessment.
Mr Gunn said having four operational dogs had been a key goal for Aspiring Avalanche Dogs, following the death two years ago of Zeppelin - who was shot by a farmer, and the retirement of Blizzid from active search duties at the end of the 2011 season.
At that time, the not-for-profit organisation went from having three operational dogs and one trainee, to three trainees and one operational dog.
''For us to come back and now have four operational teams is quite an achievement.
''We want to ensure a succession of handlers coming through ... and encourage older handlers to get new dogs when their first dog's retired.''
Aspiring Avalanche Dog handlers work on a voluntary basis but receive product support through the organisation's sponsors.
They are on call to provide a ''primary response service'' to the region as part of NZ LandSAR Search Dogs. The assessors at the recent camp were NZ Police dog handlers and representatives from NZ LandSAR Search Dogs.
Achieving a pass was no easy task, Mr Gunn said.
''It's never a given; it's always very stressful for everyone involved.''
Snow Farm, where the South Island assessments have been held for the past few years, was an ''absolutely amazing venue'', he added.
