Shamus Young (13), Archie Chittock (12), and Flynn Hill (12), won the AgriKidsNZ grand final in Hawke's Bay on Friday.
The award for competitor of the year went to Ben Cairns (10), a member of Limehills School team the Underdogs.
The Hogget Haggis team was coached by Kirsten McIntyre and beat 60 other pupils from around New Zealand to win the event in cold and wet conditions on Friday.
''We're so excited. It's an awesome result,'' Archie said.
''We've been doing a lot of study in the lead-up to the final.''
Pupils competing in teams of three tackled modules which included livestock breeding and genetics, farm safety, fuel storage, healthy soils, an agri-sector quiz and a race-off.
Shamus said their favourite module involved checking the sprockets and fitting the chain on to a two-wheeler Honda farm bike.
The pupils thanked the local businesses and their families who supported them on their journey to Hawke's Bay.
''We probably wouldn't have done as well as we did without their support,'' Flynn said.
''Special thanks goes to Ms McIntyre.''
The three boys had qualified for the national final after coming third in the Otago/Southland regional final in Milton in February.
They had been meeting at lunchtime three days' a week to grow their skills and knowledge of the agri-food sector.
''They have worked extremely hard,'' Ms McIntyre said.
''I've been testing them on hundreds of agricultural-related questions.''
''We've been on field trips to farms, the local mechanic and spoken with experts from Ravensdown and New Holland,'' she said.
''The students have asked a lot of questions and have been really committed to giving it their best go.''
