Upper Atiamuri School Year 4 pupil Emily Armer, 8, was one of only three from the school who was entered in the event and was excited to show off her pet lamb, Beauty.
"Beauty is best at leading and my favourite thing about her is that she stands out because of her black wool."
Emily's mum, Amy Armer, said her daughter sacrificed a lot to be in the competition.
"Emily has been doing everything on her own. She's been feeding Beauty three times a day so we weren't able to go anywhere during the school holidays," she said.
Lake Rerewhakaaitu School Year 4 pupil Daniel Robinson, 9, entered his calf Pacey, who he's been training and looking after since August.
"I love Pacey. The thing she is best at is being my friend."
Daniel's parents Angela and Julian Robinson said this had been a great way of teaching him responsibility and had enjoyed seeing his relationship with Pacey grow.
Other schools involved were Galatea, Reporoa, Ngakuru, Waikite Valley, Mihi, Broadlands, Kaharoa and Mamaku.
Group Day 2018 will be held at Lake Rerewhakaaitu School.
