The other Ahuwhenua Trophy finalists included Tiniroto farmers Marty and Janice Charteris, while 19-year-old Taane Hubbard, of Wairoa, was a Young Farmer finalist.
Mangaroa Station and the Hadfields are a significant farming success story, stemming from the couple's farming of a 3200 stock-unit property near Taihape and Mrs Hadfield's King-whanau operation near Whangamomona.
The resources were pooled in 2001 to lease neighbouring properties Mangaroa in the valley and Ruakaka Station, in the Tiniroto area, with a goal to build equity for family members to buy their own farms.
Mangaroa was purchased in 2002 and equity built by limiting costs, including keeping shearing within the family. Bart Hadfield and his wife's brothers had all been shearers, Bart Hadfield having in 1997 helped set a three-stand lamb shearing world record. The two are well known as organisers of the Wairoa A and P Show shearing championships, and Bart Hadfield is a competition judge.
Hannah Wallace works between the roles of shepherd general on the 1500ha, 5600-stock farm of farm of parents Richard and Harmony Wallace, and with her partner helps manage Rotanui Station.
She has been training with Primary ITO since 2011, completed a Level 4 National Certificate in sheep farming and plans studying for a Diploma in Agribusiness Management with a dream of running her own farm. She also has a close association with the Wairoa A and P Show, the family being involved in the show's rodeo.
