They are competing for the title of the National Bank Young Farmer of the Year award.
After being grilled on Thursday on their theoretical knowledge of agriculture which involved an interview and writing a business plan, they got the chance yesterday to show just how useful they are on the farm.
That meant completing tasks as diverse as building a mailbox, connecting a water trough, assembling a beehive and showing first-aid skills.
There were also four half-hour challenges of specific tasks involving sheep, dairying, deer and cropping.
Event spokeswoman Kate Taylor said time management was crucial, but not at the expense of quality of workmanship.
The finalists will not know how successful they were in the first two rounds of competition until tonight's question and answer section, which will be televised live from the MLT centre in Gore.
The winner will walk away with a first prize valued at $102,000.
