The competition alternates each year between the sheep and beef, horticulture, and dairy sectors. This year the competition is for dairy.
"With more land being used in more innovative ways, Māori agribusiness is booming," O'Connor said.
Profits for Māori agribusinesses hit $97 million in 2018, almost double from the year before, the latest Stats NZ figures show.
Māori Development Minister Willie Jackson said the rise of Māori agribusiness was impressive, especially given its unstinting commitment to all aspects of sustainability.
"We are seeing great developments in all productive sectors and a trend of Māori playing an increasingly significant role in producing higher value food and fibre products," Jackson said.
Kingi Smiler, chairman of the Ahuwhenua Trophy Management Committee, agreed and said despite the Covid-19 pandemic, farm gate returns for dairy farmers remained solid and consumers worldwide were looking for high-quality, sustainable products that Kiwi farmers and processing companies produce.
Associate Agriculture Minister Meka Whaitiri congratulated all of the finalists.
"The Government is committed to working with Māori farmers to ensure a valuable future for Aotearoa," Whaitiri said.
Each of the Ahuwhenua Trophy finalists will showcase their properties at public field days in March and April, before a winner was announced in New Plymouth on May 14.
