The girls compete in teams of three. Ten teams took part last year, 24 have registered for next week's event.
Students will tackle eight modules putting their taste buds and general knowledge to the test.
"Competitors will have to identify different varieties of apples, correctly erect a temporary electric fence and there will be blindfolded taste test," she said.
"The aim of the event is to encourage younger students to consider a career in the primary industries."
"We also want to show them you don't have to be off a farm to join the TeenAg club," she said.
Smith has been the club's chair for 12 months and plans to study a Bachelor of Commerce (Agriculture) at Lincoln University.
"We had lots of inspiring guest speakers who've shown us all the opportunities for women in the primary industries," she said.
The 17-year-old, who lives on a 380-cow dairy farm, grasps every opportunity she can to learn new skills.
Smith is one of 170 students from across New Zealand taking part in a unique leadership course run by NZ Young Farmers.
The Leadership Pathway Programme (LPP) is a collection of five learning modules for TeenAg members.
The modules focus on membership, fundraising, sponsorship, events and running an annual general meeting (AGM).
"I've completed all five. What I learned came in really handy when sourcing prizes from Rabobank and Farmlands for our event."
The leadership programme is funded by the Red Meat Profit Partnership (RMPP).
It's been developed to identify emerging leaders and ensure they're entering career pathways in the primary industries.
• Next week's event takes place on Thursday 29th November from 1pm-3pm at Southland Girls' High School.
