Those in the trade area could expect a few questions from the teens.
"None of those coming have ever been to the show at all, so have little understanding of just how big it is. I think they will be blown away by what they see and how important it is to our community from a business point of view."
Karamu High School Year 12 dean and English teacher Emma Wiggins will be taking students to the show and hopes to increase the presence of equestrian sport within the school.
"We are a fairly urban school and we are keen to build the sport of equestrian," Ms Wiggins said.
The school has a handful of "committed equestrians" and the students heading to the show are mostly riders. Karamu also has two students competing at HOY and the visiting group are hoping to see Hunter Durrant and Kate Browning in action, as well as former pupil Melody Matheson who continues to do well in showjumping.
Karamu offers equestrian studies as a correspondence course.
"This is an opportunity to support those riding at HOY and encourage the others."
Ms Wiggins said the students were keen to see behind the scenes and looked forward to meeting some of their equestrian idols, including the Wilson Sisters of popular television show, Keeping up with the Kaimanawas fame, and Olympian Maurice Beatson.
Plans are afoot to extend the invitation to more schools next year.
