Winning the national award brought Mr Bertram, who contract milks 260 cows for David and Lorraine Osborne of Featherston, a prize package worth $30,500.
Names of the winners in all three categories were embargoed last night meaning the successful contestants were not able to be interviewed before this edition of the newspaper went to press.
The judges noted Mr Bertram has developed his own feed budgeting spread sheet to help his decision making and nitrogen and supplement inputs to ensure pasture targets are met.
Runner-up in the farm manager contest was Ngatea contract milker Simon Player and third place went to Oxford farm manager Phillip Columbus.
In the other categories Charlie and Jody McCaig, of Taranaki, were named 2014 New Zealand Sharemilker/Equity Farmers of the Year and Ruth Hone representing Central Plateau was crowned 2014 New Zealand Dairy Trainee.
Miss Hone is the first woman to win the dairy trainee title and the McCaigs are the 25th winners of the sharemilker contest.
The competition celebrated the milestone with an Anniversary Ball following the awards presentations. It is the longest-running dairy farming competition and has its roots in Taranaki, where the contest idea was born in the 1970s before the first national competition was held in 1990.
Regarding the farm manager's contest Mr Irvine said the use of smart phones and other technology on farms was helping in day-to-day tasks.
"On one farm all staff had smart phones so they could access certain things, like rosters and milking procedures. They were also using snapchat to capture things like a leak on a water line," he said.
Mr Irvine said one farm was applying effluent, with solids removed, through irrigators.
"By using GPS technology they were able to cut the switch so the irrigator stops applying as the pivot moves over a water lane or sensitive area.
"It's clever stuff."
