Mr Black's dream will become a reality in July, when he represents Aorangi at the 50th grand final.
He won the Aorangi Regional Final in April. It was his fourth time competing in a regional final.
''I'm absolutely ecstatic,'' said Mr Black, who is a Christchurch-based rural consultant for New Zealand Agri Brokers.
''But I'm definitely conscious of the fact that I don't get a lot of time to hone my practical skills.''
The 25-year-old gets to spend up to a fortnight in gumboots each spring when he returns to the family farm in Southland.
''I take annual leave and head home to help with the lambing beat. It's something I look forward to every year,'' he said.
''My family has about 5000 ewes. We do twice-daily checks, assisting ewes having difficulty lambing and identifying mismothered lambs.''
''The aim is to try to get as many lambs as possible born alive and then to keep them alive,'' he said.
Mr Black moved to Christchurch last December after working as a banker in Ashburton.
His new job with Agri Brokers keeps him busy.
''I do governance and strategic planning for farms. It's about understanding the bigger picture and problem-solving to achieve a result.''
Mr Black completed a Bachelor of AgriScience at Massey University, where he was vice-chairman of Massey Young Farmers. He went on to chair the Christchurch City and Hinds clubs and eventually the Aorangi Region.
He sees the contest as a great tool for skill development and learning.
''It's a chance to benchmark myself and put my knowledge to the test.
The contest is addictive. It pushes you to your limits.''
''Some of the modules are designed so you don't have enough time to complete them. It's about how you cope as a person in a really trying situation,'' he said.
