Amelia and Erin were overwhelmed and humbled by the win and very proud that two young woman beat all the boys to take the title.
"It's pretty cool that we're both girls," said Erin, originally from Pigeon Bay.
"It's really empowering, it's a good boost to get into the industry and it's really encouraging," said Amelia, from Greendale.
The duo are boarders at Christchurch Girls' High and are both 17 years old. Leaving school next year, they both plan to do a bachelor of AgriScience at Lincoln University.
Their second Grand Final, the pair competed last year and placed first in the exam.
This year, they battled through a day of rain, bad weather and modules involving kumara – a Northland staple but somewhat foreign to two Cantabrians.
"I found parts of the farmlet generally the toughest for me, I had to rely on Erin for the practical side of it a lot so it was definitely a team effort," Amelia said.
Their advice for other young women and girls was to just get into it.
"The competition is so much fun, we've done it every year and never placed before till last year. It's just so much fun and you learn so much and meet so many new people, it's great."
The top two teams from all seven New Zealand Young Farmers' regions qualified for the Grand Final from their regional final, held near the start of the year.
Contestants completed an exam on Thursday before heading into Practical Day on Friday.
They also had to present a 10-minute speech in front of a panel of judges on one of two topics: does "NZ have a responsibility to the world to keep increasing food production to cater to the rising global population, or technology has changed how food is produced – discuss the impact of food being produced in a laboratory as opposed being field grown."
The teams' skills and knowledge of the food and fibre sector were tested through a series of modules on practical day, which included; pre-use checks on a quad bike and securing a trailer, planting and soil requirements to grow kumara, matching wool traits and samples, calf welfare and humane disbudding, reassembling a chainsaw while using the correct safety equipment and assembling a watertight vessel to transport and collect as much water as possible to put out a 'fire'.
They also went head-to-head in a 'farmlet' challenge which they had two hours to complete.
Teams had to construct a footbridge across a waterway, strong enough to hold a judge walking across it. They were also tested on their know-how of riparian planting, and were judged on their ability to identify where and why a riparian strip was required and how it should be laid out and planted.
New Zealand Young Farmers Chief Executive Lynda Coppersmith said it was fantastic to see high school students' knowledge of the food and fibre sector on full display.
"Firstly I would like to say a massive congratulations to Amelia and Erin who are two amazing young women and so deserving of the title. I also want to congratulate our other place getters and the rest of the contestants who competed over the last two days.
"New Zealand Young Farmers' purpose is to excite young people about all of the possibilities in the food and fibre sector so it's great to see such an enthusiastic bunch of winners who embody the knowledge and innovation needed to excel in such a diverse industry.
"All 14 Grand Final teams and those who competed in Regional Finals truly are an inspiration to the future of the industry."
