The common theme, however, is the re-creation of traditions lost, and the attitude immortalised in the latin phrase Carpe Diem - seize the day.
"The Rathkeale Tramping Club was very strong in the '60s, '70s and '80s," says teacher Joe Nawalaniec.
"It became less popular in the '90s and by the 2000s it had disappeared.
"Now tramping is becoming more popular; the numbers are growing hugely this year."
It was students, not teachers, Mr Nawalaniec said, who this year "asked for the old Rathkeale Tramping Club to be reconstituted".
"They put it to the principal Mr [Willy] Kersten."
With the help of teachers such as Mr Nawalaniec and Alistair Barr - a tramper of some 50 years' experience - the Rathkeale boys along with senior girls from St Matthew's have taken to the Tararuas and tackled some significant tramping challenges.
Mr Nawalaniec, a science and chemistry teacher, said he has "always been into anything outdoors - tramping and mountaineering" - and is keen to share that passion.
"They're a tough bunch of boys and girls, and it's my privilege to encourage them and push them in that area," he said.
Missions included the photographed climb of Mount Holdsworth on Sunday, June 23.
"The group took an unorthodox route via Holdsworth Stream, and up a spur through leatherwood and heavy snow, direct to the summit," Mr Nawalaniec said.
"The snow was one metre deep in places, and the group encountered hard ice as well."
Other trips this year have included a descent of the mid Waiohine Gorge via Hector Forks - "the biggest gorge in the Tararuas".
There was also a "gnarly Mt Bannister crossing" which included some high-altitude tenting.
All tramps so far have included the loyal Rathkeale Tramping Club mascots Sushi the fox terrier and Floyd the spoodle.
